Abstract
The present disclosure provides a method of perceiving a position and pose of a hydraulic support group based on multi-point ranging and belongs to the field of test or measurement technologies unlisted in other categories. The method uses a hydraulic support group. The hydraulic support group includes multiple juxtaposed hydraulic supports. The method includes: with a plane above a base as a reference plane, establishing a reference coordinate system; perceiving a relative position of the base and a canopy of the hydraulic supports and perceiving a position and pose of a single hydraulic support; when the hydraulic supports have axial offset and roll phenomenon, performing offset amount calculation; based on the perception of the position and pose of single hydraulic supports, performing perception on the position and pose of the hydraulic support group. In the present disclosure, the measurement devices achieve conversion of pure distance information into three-dimensional pose information of an object in time and space by using logical combination of several real-time ranging terminals, leading to simple structure; there is no interference between measurement devices, and there …
