The invention relates to the technical field of sensors, in particular to a travelling crane hoisting safety detection method and
system based on multi-sensor calibration, a camera and a
radar serve as a multi-sensor unit,
timestamp synchronization is carried out on data collected in real time,
data association is carried out on detection information of continuous frames, and the detection result is obtained. The method comprises the following steps of: keeping correlation consistency of front and back frames of a detected object, clustering, filtering and optimizing steel coil point clouds, calculating the length, width and
terrain clearance of a steel coil, calculating the outer contour of the point clouds, realizing fusion of a plurality of multi-sensor units, splicing and fusing the generated point clouds, and converting the point clouds into a unified coordinate
system. According to images and
point cloud information collected by the visual
radar sensors at the two ends of the travelling crane, the positions of the
pedestrian, the suspension arm and the steel coil can be accurately captured and calculated, and the relevant parameters of the
pedestrian, the suspension arm and the steel coil are calculated. And when the
pedestrian moves into a dangerous range of the hung steel coil, the alarm on the driving control board card automatically gives out a
ringing alarm.
