Background

The railway track detection is an indispensable working part for the safe operation of a railway network, and in the railway track detection work, the surface of a railway (comprising a track, a sleeper, a fastener, a roadbed and the like) needs to be photographed to obtain image data of the railway, wherein the image data is used as basic data of the track detection to be filed, analyzed for defects, retrieved and checked; and meanwhile, the system is used as the input of other systems to carry out relevant processing (such as defect detection and the like).

In the prior art, a method adopted for railway track detection is that optical image acquisition equipment (usually a linear array camera) is installed at the bottom of a track detection vehicle, rapid image acquisition is carried out on the surface of a railway below according to the vehicle speed, and continuous image acquisition forms a continuous railway image so as to cover a detected railway section. When the linear array camera works, the collected image data are transmitted to the front-end collection server, and the front-end collection server compresses the received image data into a JPEG format and writes the JPEG format into a storage device or transmits the JPEG format to a third party through a network.

Meanwhile, along with the popularization of high-speed railways, the speed of the track detection vehicle is increased, and the situation that the image compression speed of a front-end acquisition server is lower than the image acquisition speed often exists, so that data acquired by the track detection vehicle is lost due to insufficient compression, and the integrity and the accuracy of an acquisition result are seriously influenced.

This invention may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

For example, it may be implemented using any number of the apparatus or performing methods set forth herein.

It is to be understood that any aspect disclosed herein may be embodied by one or more elements of a claim.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

In the prior art, a method for detecting a railway track is to install a track detection system on a track detection vehicle, wherein the track detection system comprises a track image detection subsystem. The track image detection subsystem comprises an optical image acquisition device (usually a linear array camera) arranged at the bottom of the track detection vehicle, the optical image acquisition device is used for rapidly acquiring images of the surface of the railway below according to the vehicle speed, and continuous image acquisition forms a continuous railway image so as to cover the detected railway section.

When the linear array camera works, collected image data are transmitted to a front-end collection server, the front-end collection server compresses and codes the received image data through special hardware equipment or a software program to generate continuous picture data, the compression format of the picture data is JPEG, and then the compressed picture data are written into a storage device or transmitted to a third party through a network.

With the increase of railway mileage and the improvement of the resolution of the camera device, the acquired railway image data is huge in data volume, and the hardware cost required for storing and processing the huge data volume is extremely high. Meanwhile, along with the popularization of high-speed railways, the speed of the track detection vehicle is increased, and the situation that the image compression speed of a front-end acquisition server is lower than the image acquisition speed often exists, so that data acquired by the track detection vehicle is lost due to insufficient compression, and the integrity and the accuracy of an acquisition result are seriously influenced.

In order to solve the above problem, as shown in fig. 1 and 2, an embodiment of the present invention provides a railway track image processing method, including the steps of:

step S100: acquiring railway track image data; the railway track image data may be image data acquired in real time by an optical image acquisition device installed at the bottom of the track inspection vehicle, or may be existing image data acquired from other storage devices, and the acquisition mode may be acquired through a wired transmission way or a wireless transmission way, which is not limited herein.

Step S200: video coding the image data to form a first type frame I_aAnd a second type frame group P_aWherein the second type frame group P_aIn a first type frame I_aAnd a first type frame I_a+1A is traversed from 1 to m, a is the serial number of the first type frame and the group number of the second type frame group, and m is the number of the first type frame and the number of the second type frame group;

the second type frame group P_aComprising at least one frame P of a second type_a ^bB is traversed from 1 to n, b is the serial number of the second type frame, and n is the number of the second type frames contained in each second type frame group;

the first type frame I_aStoring complete image information, and decoding independently;

said second type frame P_a ^bNot separately encodable, when b is 1, said second type frame P_a ^bStoring and first type frame I_aThe delta data of (a); when b is>1, said second type frame P_a ^bStoring and second type frame P_a ^b-1The delta data of (a);

frame I of the first type_aIt belongs to intra-frame compression, which is the complete reservation of this frame of picture, and only this frame of data is needed to complete the decoding (because it contains complete picture).

Frame P of the second type_a ^bThe method belongs to inter-frame compression, and has no complete picture data, and only has data of picture difference with a previous frame (the previous frame may be a second type frame or a second type frame), so that the difference defined by the current frame needs to be superimposed by a previously buffered picture when decoding, and a final picture is generated.

Step S300: frame I of the first type_aAnd a second type frame group P_aForm an image group G_aAnd a is traversed from 1 to m. Thus, image group G_aIs the first type frame I_aIs added to the second type frame group P_aP of the second type frame contained in_a ^bThe number of the cells. In addition, one image group G_aIn which there is only one frame of the first type I_aBut there may be no or several frames P of the second type_a ^b。

When the image group G_aWhen the length of (1) is 1, it means that there is no second type frame P_a ^bOnly the first type frame I_aDue to the first type frame I_aIncluding a complete picture, it can be decoded independently, but also results in a large amount of data.

When the image group G_aWhen the length of (1) is larger than 1, the image group G_aThe longer the length of (B), the second type frame P is possessed_a ^bThe more this way, the higher the compression ratio, but the longer the decoding operation time.

Therefore, the image group G should be selected as appropriate according to actual needs_aI.e. each image group G_aIncluded second type frame P_a ^bThe number of the cells.

In the traditional solution, a JPEG compression format is adopted, the effective range of data compression limits frames, and no association relationship exists between each frame of data. However, for the railway track image, it has a certain particularity, that is, there is a greater similarity between the image frames, based on this feature, the principle of video coding is introduced in this embodiment, and the railway track image data is video-coded to form the first type frame I_aAnd a second type frame P_a ^bAnd forming an image group G_aIn the first type frame I_aIn a second type frame P, in which the complete image is stored_a ^bThe method greatly improves the compression rate of the railway track image data by the differential compression mode, thereby effectively reducing the data volume of the railway track image data.

It should be noted that, although the video coding technology is an existing image processing technology, it is not yet seen that the existing technology applies it to a processing method of railway track image data. In the technical field of railway track image identification, because an image in a picture format is acquired, a common processing method is to compress the picture format into a JPEG format by using a special device so as to compress the image data volume. Therefore, it is not easy for those skilled in the art to apply the video compression technique to the technical field of railway track image data processing.

The method for processing the railway track image data further has the following beneficial effects:

1) in the process of image processing by adopting the method of the embodiment, the generation amount of image data per second can be controlled by controlling the code rate parameter of video coding, the problem of data loss caused by the inconsistency of the railway track image acquisition rate and the image compression rate is avoided, and the method is favorable for image data storage and image data network transmission.

2) By adopting the image data processing method of the embodiment, when the user needs to use the related image data, the decoding processing is carried out through the standard hardware video processor of the computer platform, so that the decoding speed can be increased, and the load of the CPU can be reduced.

Further, in step S100, after the railway track image data is acquired, at least one of the following steps is further included:

step S110: caching the acquired image data to a data cache region of a video memory; thus, when the GPU or VPU is adopted to process the image data, the data exchange speed can be improved.

Step S120: preprocessing the image data, wherein the preprocessing content at least comprises one of the following contents: enhancing image brightness, equalizing histogram and overexposing image area.

The preprocessing of the image data is operated by the GPU shader, and can be executed in parallel. For each frame of image data, the content of the image can be clearer by performing necessary preprocessing before encoding, and the content of the preprocessing is determined according to practical situations, including but not limited to the following: image brightness enhancement, histogram equalization, image region overexposure processing, and the like.

It is understood that, in the railway track image data processing method provided by the present invention, step S110 and step S120 may be provided at the same time, or only step S110 or step S120 may be provided.

Further, in the step S200, each second type frame group P_aOf the second type frame P contained therein_a ^bThe number n of (a) is in the range of 1 to 9.

Due to the image group G_aOf the first type frame I it contains_aIs added to the second type frame P (number 1)_a ^bAnd one image group G_aIn which there is only one frame of the first type I_aGroup of images G_aIs made up of a second type frame group P_aOf the second type frame P_a ^bThe number of the cells is determined.

When the second type frame P_a ^bWhen the number of (2) is 0, at this time, the image group G_aIn only the first type frame I_aDue to the first type frame I_aContains complete pictures and can therefore be decoded independently, but again leads to the problem of large data volumes. When the second type frame P_a ^bIs greater than or equal to 1, the second type frame P_a ^bThe larger the number of the image groups G, the more the number of the image groups G_aThe longer the length of (b), the longer the decoding operation time required, although the compression ratio of the image data at this time is higher, resulting in a delay in decoding. Therefore, the suitable second type frame P should be selected according to the actual requirement_a ^bThe number of the cells. Preferably, one image group G_aOf said second type frame P included in_a ^bThe number of the frame is 1-9 frames, which can meet the requirement of track detection application.

Further, as shown in fig. 3, after the step S300, at least one of the following steps is further included:

step S400: the image group G_aTransmitting to a memory cache region for caching;

step S500: for the image group G_aAdding structural description information to form extended data, wherein the structural description information at least comprises one of the following information: image sequence information, image information.

It is to be understood that the image data processing method according to the above-described embodiment may include both step S400 and step S500, or may include only step S400 or step S500.

Wherein: the image sequence information includes, but is not limited to, the information shown in table 1, and the image information includes, but is not limited to, the information shown in table 2.
