More Information
Summary:The embodiment of the invention provides an object detection method, device and equipment. The method comprises the steps that the opening and closing state of an elevator door is determined according to multiple first distances collected by first laser ranging equipment; when the elevator door is in the open state, first point cloud data collected by second laser ranging equipment is obtained, and the first point cloud data comprises a plurality of three-dimensional coordinates; at least one three-dimensional coordinate set is determined in the multiple three-dimensional coordinates, the value of the three-dimensional coordinates in the three-dimensional coordinate set in the first direction is a first preset value, and the three-dimensional coordinates in the three-dimensional coordinate set are continuous on a preset plane; determining at least one extended coordinate set corresponding to the at least one three-dimensional coordinate set, wherein the three-dimensional coordinates in the extended coordinate
