Embodiment Construction
[0059] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0060] A cargo positioning method based on Fourier-Mellin transform, comprising the following steps:
[0061] Step 1, establish an absolute coordinate system,
[0062] Before the mobile robot moves,
[0063] Artificially set multiple calibration points in the coordinate system. The calibration points are set on the moving path to mark the position of the shelf. The absolute coordinates of each calibration point are known, and the positional relationship between the marking point and the shelf is also known;
[0064] Identify the calibration point and locate the position information of the shelf;
[0065] The specific method of identifying the calibration point and locating the location information of the shelf includes: the calibration point is fixed on the ground or on the shelf, the relative position of the calibration point and the s...
