Detailed Description

To further explain the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description is given with reference to the accompanying drawings and preferred embodiments.

The invention provides a method for cleaning dust attached to a windshield and intelligent glasses.

Fig. 1 is a schematic flow chart of a method for cleaning dust adhering to a windshield according to a first embodiment of the present invention, and fig. 2 is a schematic logic diagram of a determination of the method for cleaning dust adhering to a windshield according to the first embodiment of the present invention. As shown in fig. 1 and 2, a method for cleaning dust adhering to a windshield according to a first embodiment of the present invention includes the steps of:

s1: the intelligent glasses detect whether dust exists in the area where the windshield of the vehicle is located, and when the fact that the dust exists in the area where the windshield is located is judged, the step S2 is carried out;

in this embodiment, the step may specifically include:

acquiring an image of an area where a front windshield is located through a camera on the intelligent glasses;

identifying windshield glass and dust according to the collected image;

and judging whether the position of the dust is superposed with that of the windshield, and judging that the area of the windshield has the dust when the position of the dust is superposed with that of the windshield.

S2: judging whether the dust is on the windshield, and when the dust is on the windshield, proceeding to step S3;

in this embodiment, the step may specifically include:

recording and judging the time point of dust in the area of the windshield;

the intelligent glasses send first request information outwards, and the first request information requests to acquire the environment information outside the vehicle at the time point and the environment information inside the vehicle at the time point;

specifically, after the vehicle acquires this information, can gather plantago image through the camera before the car, then judge whether the environment is the first negative environment that the floater quantity is greater than first settlement threshold value for the environment outside the car according to the image that the camera was gathered before the car to transmit this judged result to intelligent glasses.

After the vehicle acquires the information, the vehicle interior image can be acquired through the vehicle interior camera, then whether the vehicle interior environment is a second negative environment with the number of the floating objects in the air larger than a second set threshold value or not is judged according to the image acquired by the vehicle interior camera, and the judgment result is transmitted to the intelligent glasses.

And when the outside of the vehicle is not in the first negative environment and the inside of the vehicle is not in the second negative environment, judging that dust is attached to the windshield.

Through the steps, the influence of the floating objects in the environment outside the vehicle on the judgment result can be eliminated. The possibility of misjudgment of the vehicle in the sand and dust days and in the poplar dust road section is reduced. Meanwhile, the influence of floaters in the environment in the vehicle on the judgment result can be eliminated, and the possibility of misjudgment caused by smoking of passengers in the vehicle is reduced.

Further, the first request message can also request to acquire the state information of the camera of the intelligent glasses;

specifically, after the vehicle acquires the first request information, whether the camera of the intelligent glasses is in a clean state without dust adhesion can be judged according to the image collected by the camera in the vehicle.

When the outside of the vehicle is not in the first negative environment and the inside of the vehicle is not in the second negative environment, and the camera of the intelligent glasses is in a cleaning state, it is judged that dust is attached to the windshield.

Further, when the camera of intelligence glasses is not in clean state, when also having the dust above that, the outside camera that sends of intelligence glasses needs the clearance to remind.

S3: the intelligent glasses send out dust cleaning signals outwards so that the dust on the windshield can be cleaned by the vehicle.

After the vehicle receives the dust cleaning signal, the vehicle can spray glass water to the windshield and start a wiper so as to clean dust on the windshield.

Furthermore, when the vehicle cleans the windshield, the intelligent glasses can also collect images of the windshield wiper during swinging, and whether the windshield wiper can block dust is judged according to the collected images;

when the wiper does not block dust, acquiring an image of a windshield after the wiper stops, and judging whether the dust is removed or not; when the dust is not removed, sending a dust cleaning signal outwards again;

when the wiper blocks dust, that is, when the wiper is located between the dust and the windshield, it can be judged that the dust is not located on the windshield; no dust cleaning signal is sent outwards any more.

Further, after the dust cleaning signals are sent for the set times, if the dust is judged to be still unclear, a reminding message is sent outwards to remind a user of manual clearing or confirmation of the dust position.

In this embodiment, can judge whether there is the dust on to the windshield through intelligent glasses to after having the dust on judging the windshield, clear up this dust through the vehicle, this can make intelligent glasses can assist the driving action better.

Fig. 3 is a logic diagram illustrating a determination of whether dust adheres to a windshield according to a second embodiment of the invention. As shown in fig. 3, in the second embodiment of the present invention, when determining whether the dust is on the windshield, it may include the steps of:

measuring the direction and distance of dust relative to the intelligent glasses by using a ranging camera on the intelligent glasses; measuring the position and the distance of the windshield at the position overlapped with the dust relative to the intelligent glasses;

judging whether the positions of the dust and the windshield are overlapped;

when the positions of the dust and the windshield coincide, the dust is judged to be positioned on the windshield.

Fig. 4 is a logic diagram illustrating a determination of whether dust adheres to a windshield according to a third embodiment of the invention. As shown in fig. 4, in the third embodiment of the present invention, when determining whether the dust is on the windshield, it may include the steps of:

the intelligent glasses send second request information outwards, and the second request information requests to acquire whether the vehicle is in a traveling state or not; after the vehicle acquires the request information, the traveling state of the vehicle may be acquired from the vehicle speed sensor.

When the vehicle is in a running state, collecting images of an area where dust is located for multiple times at set time intervals, and judging the movement trend of the dust relative to the windshield according to the collected images for multiple times;

when the dust is stationary with respect to the windshield, it is judged that the dust is on the windshield.

In summary, by using the method for cleaning dust adhered to the windshield provided by the invention, whether dust exists on the windshield can be judged through the intelligent glasses, and after the dust exists on the windshield is judged, the dust is cleaned through the vehicle, so that the intelligent glasses can better assist driving behaviors.

The invention further provides intelligent glasses, which comprise a computer storage medium, wherein the computer storage medium comprises a computer program, and when the computer program is executed, the method for cleaning dust attached to the windshield is realized.
