Embodiment 1
[0031] This example discloses a real-time measurement method for the kinetic energy of the drilling support platform based on visual positioning, such as figure 1 shown, including the following steps:
[0032] S1 collects images of different postures of the drilling support platform as the training atlas of the convolutional neural network.
[0033] The images of different attitudes are obtained by the camera, the nonlinear model of the camera is established, the distortion parameters of the camera are obtained through the nonlinear model of the camera, and the images of different attitudes are corrected according to the distortion parameters.
[0034] Among them, the process of establishing the nonlinear model of the camera is:
[0035] Such as figure 2 As shown, suppose a point P in 3D space W (X W ,Y W ,Z W ) in the camera coordinate system is (X C ,Y C ,Z C ), the coordinates projected in the image physical coordinate system are (x, y), and the upper left corner ...
