Embodiment Construction

[0074] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0075] Such as Figure 1~4 Shown, a kind of airborne video sweeping reconnaissance method to the ground, the specific steps of this method are as follows:

[0076] Step 1: Solve the initial video frame. Establish the basic coordinate system, and solve the coordinates of 5 points of the video frame when the swing angle is 0; the specific method is:

[0077] (101) Establish a basic coordinate system. The origin of the coordinate system is (0,0,0), the x-axis is the heading, and the y-axis is the right side of the wing (the z-axis is determined by the right-hand rule);

[0078] (102) Taking the vertical direction of the load to the ground as the direction of 0 degrees, then the coordinates of the five points of the video ...

Abstract

The invention discloses an airborne video ground sweeping reconnaissance method, which relates to the field of aircraft guidance and navigation. The method of the invention realizes the sweeping and reconnaissance of the ground through the steps of transforming the coordinate system, solving the periodic law of the video frame, and dividing the reconnaissance area. The method can improve the reconnaissance efficiency, reduce the non-coverage rate of reconnaissance coverage, and effectively solve the problems of low reconnaissance coverage efficiency and coverage blind spots in video reconnaissance.

Description

technical field [0001] The invention relates to the technical field of aircraft guidance and navigation and unmanned aerial vehicle video reconnaissance, in particular to an airborne video ground sweeping reconnaissance method. Background technique [0002] With the development of guidance and navigation technology, UAV video reconnaissance technology has gradually become a hot research issue, and it has been more and more widely used in reconnaissance surveillance, aerial surveying and mapping, etc. In particular, the video reconnaissance, which uses video sweep imaging as the payload, has attracted extensive attention from scholars at home and abroad. Since the current video reconnaissance does not consider the motion characteristics and imaging rules of video sweeping, there are problems of blind spots and low efficiency in reconnaissance coverage. [0003] Scholars at home and abroad have conducted in-depth research in this field: Xu Anqi and others used the cell decomp...
