POS management system for aerial surveying of unmanned aerial vehicle

Abstract

The invention discloses a POS management system for aerial surveying of an unmanned aerial vehicle and belongs to the technical field of aerial surveying equipment. The POS management system comprises a processor which is connected with a heat boot signal sensor and is used for connecting an aerial surveying camera heat boot, recognizing a heat boot signal, judging if the aerial surveying camera executes a shooting action and meanwhile controlling the acquired POS data to be stored in a SD card. According to the invention, the heat boot signal of the camera is used for triggering the record of the POS data, so that a synchronization mechanism is formed and the complete data can be guaranteed; the POS data reading efficiency is increased; and the high-precision POS data collection is realized, a consuming type camera can achieve the high precision of a professional aerial surveying camera through an additional module, and the cost is greatly lowered.

Description

technical field [0001] The invention discloses a POS management system applied to aerial survey of unmanned aerial vehicles, belonging to the technical field of aerial survey equipment. Background technique [0002] The application of UAV remote control navigation survey is more and more extensive. In order to obtain high-precision aerial survey results, various external orientation data such as three-axis attitude and position coordinates during aerial survey imaging must be acquired synchronously during flight, that is, POS data, which provides basic data for later image correction, fusion, and splicing. [0003] In the prior art, the problems of aerial survey POS management technology include: [0004] (1) The flight control system sends a measurement signal to the camera. Regardless of whether the camera takes pictures successfully or not, the flight control system will record the current status of the aircraft into the POS data. Therefore, if the camera fails to take ...

AI Technical Summary

Problems solved by technology

Therefore, if the camera fails to take pictures due to some factors during the flight, it will cause a mismatch between the POS data and the image, increase the load of post-processing work, and even discard the collection work;

[0005] (2) Because the POS data collects the state of the aircraft, not the state information of the camera itself, there are errors in the collected data;

[0006] (3) Since the POS data is stored in the flight control system, after each flight, it takes time to export the POS data to the PC, which is not efficient;

[0007] (4) A large number of signal reading and data writing to the flight control will interfere with the stability of the flight control, affect the flight quality, and even lead to the risk of "explosion";

[0008] (5) After the flight, the field staff cannot analyze the flight quality, and can only be checked by the post-processing personnel; if the flight quality is not good, it must be reworked, increasing the cost

[0009] Professional aerial survey equipment is often very expensive in order to achieve high-precision data acquisition and build an efficient and accurate image processing system
