Embodiment 1
[0024] The unmanned aerial vehicle needed to realize the present invention must meet the following requirements: equipped with a high-speed camera, the camera can shoot the ground to the ground, and can transmit the captured images to the ground experiment platform for processing.
[0025] Below is a specific description of the UAV positioning and attitude angle measurement method based on coded marker points provided by this embodiment, such as figure 1 shown, including the following steps:
[0026] Step S1, use the camera mounted on the UAV to shoot a number of pre-arranged coded marker points on the ground, acquire the captured images, and process them; the coded marker points are binary coded cooperation points with initial points, such as figure 1 shown. Schematic diagram of the shooting process image 3 shown.
[0027] The image processing method mentioned in this step is specifically to acquire any number of coded marker points captured on the image, and decode and m...
