In the implementation process, the positioning position Z of the trolley is calculated by using Z ═ Z0+ Z1, which indicates that the vertical projection of the second single-line laser scanner is located on the edge of the steel plate where the point B is located as an ideal grabbing position in the embodiment (the condition that the scanning path of the second single-line laser scanner is parallel to the short side of the steel plate is unchanged), so that the movement of the trolley is compensated by the offset Z1 of the edge of the steel plate where the point B is located. Similarly, the vertical projection of the second single-line laser scanner can be located on the edge of the steel plate where the point C is located, and the transverse offset z2 is adopted to compensate the movement of the trolley.
And S250, controlling the cart and the trolley to move to the respective target positions respectively according to the positioning positions.
Illustratively, when the grabbing position of the steel plate grabbed by the unmanned overhead travelling crane is an ideal position, namely the vertical projection of the point O is located on the intersection point of the short side where the point A is located and the long side where the point B is located, at this time, the offset x and the offset z1 are both zero, the cart and the trolley of the unmanned overhead travelling crane can move to respective target positions, further, the positions where the steel plate is put down by the lifting appliance are consistent, when the steel plate is offset, namely the offset x and the offset z1 are not zero, the positioning positions of the cart and the trolley are obtained through compensation, then the respective actual positions are replaced by the respective positioning positions, when the positioning positions are overlapped with the target positions, the cart and the trolley stop moving, and at this time, the position of the steel plate is the final position of the steel plate during the ideal grabbing.
In a possible implementation scene, a first single-line laser scanner and a second single-line laser scanner respectively scan the short edge and the long edge of a steel plate to obtain a short edge intersection point A and two long edge intersection points B and C, then the distance OA between the point A and the first single-line laser scanner and the included angle a between the line segment OA and the vertical line, the distance OB between the point B and the second single-line laser scanner and the included angle B between the line segment OB and the vertical line, the distance OC between the point C and the second single-line laser scanner and the included angle C between the line segment OC and the vertical line are obtained, further the longitudinal offset x, the transverse offsets Z1 and Z2 of the steel plate are obtained through calculation processing, the actual position P0 of the unmanned aerial vehicle and the actual position Z0 of the vehicle are further obtained through positioning identification, then the positioning position P of the taxi and the positioning position Z of the vehicle are obtained through compensation through the offsets, and the respective actual positions of the large vehicle and the small vehicle are replaced by, when the positioning positions of the cart and the trolley are consistent with the respective target positions, the steel plate is moved to the target point, the steel plate is put down at the moment, the steel plate can be placed neatly, the cart and the trolley are stopped from moving, and the steel plate is put down. According to the method, the steel plate offset obtained through recognition and calculation is compensated for the movement of the unmanned overhead travelling crane, so that the unmanned overhead travelling crane can accurately move the steel plate to an ideal position, the effect of orderly placing the steel plate is further realized, and the problem that the error of the final placing position of the steel plate is difficult to control due to the uncertainty of the grabbing position of the lifting appliance, and the placing of the steel plate is uneven is avoided.
