Technical Field

The invention relates to the technical field of surveying and mapping,

in particular, the invention relates to a layer-by-layer distributed detection method for a detection cambered plate.

Background

With the development of remote sensing mapping technology, high spatial resolution remote sensing images become a main data source for applications such as precision agriculture, target identification, disaster assessment, change monitoring and the like. In practical applications, it is necessary to record the acquired high-speed real-time data, such as high-resolution image data, in real time for post-processing.

However, when the remote image is mapped, the result obtained by one-time measurement of one detection device often causes the situation of large data error, and often a plurality of detection devices are used for simultaneous detection, or one detection device adjusts the position for a plurality of times to obtain the result of multiple measurements, and then the data of the multiple measurements are integrated and analyzed, so that the accurate mapping data of the target object is obtained.

However, in the aspect of long-distance surveying and mapping, the probe head is slightly adjusted to a small distance, so that a large angle deviation and even a lost target can be detected, the probe head needs to be adjusted in real time to be aligned to the target in order to ensure the accuracy of the detection, the adjustment is very small, the adjustment distance is generally only 0.01mm to 5cm, the adjustment accuracy requirement is high, meanwhile, the target information can be accurately detected, layer-by-layer detection can be performed through a partial shielding method, the target is accurately aligned, and the target surveying and mapping information is obtained.

Therefore, how to design a reasonable detection cambered plate layer-by-layer distributed detection method becomes a problem which needs to be solved urgently at present.
