Embodiment 1
[0056] refer to figure 1 , which shows a flow chart of the steps of a self-calibration method for binocular ranging on a moving platform provided by an embodiment of the present invention, as shown in figure 1 As shown, the binocular ranging self-calibration method of the moving platform may specifically include the following steps:
[0057] Step 101: Obtain the coordinates in the target image corresponding to the target to be measured collected by the two image acquisition devices at the acquisition time, and the pose information of the two image acquisition devices when the target image is acquired;
[0058] Step 102: Determine the target position of the target to be measured according to the transmission projection equation set established by the two collected coordinates and the two pose information;
[0059] Step 103: Using the target position and the two pose information as initial values, establish an objective function that minimizes the reprojection error;
