Title:
THREE-DIMENSIONAL LASER-BASED CONTAINER TRUCK ANTI-HOISTING DETECTION METHOD AND APPARATUS, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/179983
Kind Code:
A1
Abstract:
A three-dimensional laser-based container truck anti-hoisting detection method and apparatus, a computer device, and a storage medium. The method comprises: obtaining a three-dimensional point cloud of a container operation acquired by a laser radar (S302); obtaining an attitude angle of the laser radar (S304); converting the three-dimensional point cloud according to the attitude angle (S306); projecting the converted three-dimensional point cloud into a two-dimensional image (S308); determining a position range of a gap between a container truck and a container in the two-dimensional image (S310); and performing image detection on the position range in the two-dimensional image to obtain a container truck anti-hoisting detection result (S312). The data source of the method has a high accuracy, and the detection method is not affected by the mounting position and mounting angle of the laser radar, thereby greatly improving the accuracy of anti-hoisting detection.
