Abstract

The invention relates to a point cloud sampling system and method based on laser radar scanning angle switching, and belongs to the technical field of steel stacking unmanned driving. The system comprises a control system, a three-dimensional laser radar scanning system and a human-computer interface. The control system comprises a control module, a power supply module, a storage module and an identification calculation module; the three-dimensional laser radar scanning system comprises a holder and a two-dimensional laser radar scanner; a control module controls a three-dimensional laser radar scanning system to accurately scan section bar bundles, bar bundles or wire rod bundles and stacking positions of stacks of the section bar bundles, the bar bundles or the wire rod bundles in a packaging area; scanning angle intervals are flexibly switched, and proper scanning points are selected; therefore, small-angle-range scanning of a packaging area, panoramic scanning of a stacking area and small-angle-range scanning of a stacking position of the stacking area are realized. The system is practical, novel, low in equipment cost and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of steel stack unmanned driving, and in particular relates to a point cloud sampling system and method based on laser radar scanning angle switching. Background technique [0002] With the development of automation and identification and positioning technology, unmanned driving in steel plants has become a trend. The 3D lidar scanning system is like the eyes of the unmanned driving vehicle. Through scanning, it can identify the position coordinates of the profile bundles, bar bundles, disc bundles and their stacking, and send them to the PLC to control the automatic operation of the driving through the network. [0003] The profile bundles have a rectangular cross-section, and the stacking method is multi-layer close stacking. The bar bundles have an elliptical cross-section, and the stacking method is multi-layer overlapping well-shaped stacking. The round bundles are placed on the arc side of the hollow ...
