Embodiment Construction

[0111] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific steps. The present invention discloses a method for high-precision target positioning and speed measurement based on an unmanned aerial vehicle photoelectric platform. The method specifically includes the following steps:

[0112] Step 1. Collect the precise longitude, latitude and altitude of the cooperative target point; plan the calibration route, which requires the UAV to maintain a constant speed, stable heading and altitude, and zero pitch and roll angles.

[0113] The planning of the calibration route should consider the relative position of the UAV and the cooperative target, so that the UAV can make full use of the four directions of front, back, left, and right to locate the cooperative target. The calibration route should be as follows: figure 1 The route shown or a route similar to it. In the first route 1 or the third route 3, the targe...

Abstract

The invention discloses a high-precision target positioning and speed measurement method based on a photoelectric platform of an unmanned aerial vehicle. The high-precision target positioning and speed measurement method provided by the invention includes the following steps: first, an azimuth error and a high-low angle error of the photoelectric platform are estimated according to a stationary cooperative target, after estimated values of the azimuth error and the high-low angle error of the photoelectric platform are stabilized, the stabilized estimated values of the azimuth error and high-low angle error of the photoelectric platform are utilized as the azimuth error and the high-low angle error of the photoelectric platform, and then compensation is performed on the azimuth error and the high-low angle error of the photoelectric platform in real time during a positioning and speed measurement process, and a high precision target position and speed information are output.

Description

【Technical field】 [0001] The invention belongs to the field of unmanned aerial vehicle target positioning, and in particular relates to a high-precision target positioning speed measurement method based on an unmanned aerial vehicle photoelectric platform. 【Background technique】 [0002] In modern warfare, real-time grasp of the battlefield development situation and instantaneously changing intelligence is the key to gaining the initiative on the battlefield. Therefore, effective ways and means of obtaining battlefield information are particularly important. UAVs have the advantages of small size, low cost, flexible maneuverability, and no risk of casualties during combat. At present, they are widely used in military fields such as reconnaissance and surveillance, and artillery calibration. [0003] The UAV can enter the front of the position and go deep behind the enemy, work according to the predetermined program or ground instructions, and transmit the obtained informati...
