A positioning method of unmanned aerial vehicle camera combined with target

In order to test the accuracy of the weapon hitting the target, it is very important to locate and measure the spatial coordinates of the falling point target. Aiming at the needs of space coordinate positioning and measurement of targets falling into the sea/ground plane, this paper studies a positioning method of UAV camera combined with target, and uses the principle of homography transformation to calculate the space coordinates of targets. The influence of pixel error on the positioning method is simulated by Monte Carlo method, and the shooting attitude range meeting the measurement requirements is determined by simulation. The results show that the positioning method of UAV camera combined with target has high accuracy, which can meet the needs of landing target positioning and measurement.
