Title:
BIPOLAR COORDINATE MULTI-LINE LASER BEAM STRUCTURED LIGHT METHOD, APPARATUS AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/241672
Kind Code:
A1
Abstract:
A bipolar coordinate multi-line laser beam (7) structured light, a light source device (16), a camera device (17), and control judgement logic are disclosed. The structured light contains multi-line laser beam (7) which emitted from a window by a number of narrow linear beam lasers (1) parallel to each other, and one such multi-line laser beam (7) is projected in a scene to form a polar coordinate system,two such multi-line laser beam (7) projection in the scene forms a bipolar coordinate system to achieve the positioning of the scene, at least one multi-line laser beam source (16) is arranged perpendicular to the road pavement or track plane or ground.The structured light is suitable for auxiliary cameras (17) to obtain 3D information of the scene, it can be used in machine vision applications, including but not limited to automatic driving, remote sensing telemetry, engineering 3D mapping and surveying, robots, automatic warehousing, automatic production lines, assembly lines, conveyor lines, sorting lines, detection lines and other machine vision applications.
