Embodiment Construction

[0077] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the examples of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0078] This embodiment discloses a spatial positioning system based on a contour sensor, which mainly includes a first position feature point acquisition module, a second position feature point acquisition module, and a movement parameter acquisition module, wherein: the first position feature point acquisition module mainly uses contour The sensor obtains the coordinates of the four contour feature points at the first position; the second position...

Abstract

The invention discloses a space positioning method based on a contour sensor, which mainly converts the movement relationship of an object in the space into the movement relationship of a space rectangle in the space, and solves the rotation angle and translation value of the space rectangle in a three-dimensional coordinate system by using the coordinate change of feature points on the space rectangle. The invention also provides a space positioning system based on the contour sensor. The method provided by the invention needs few feature points and is small in calculation amount; the feedback speed is fast, and errors of a contour sensor-based measurement method can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of space positioning, in particular to a space positioning method and system based on a profile sensor. Background technique [0002] With the increasing automation of industrial production. The use of robots is becoming more and more common. The production efficiency is getting higher and higher, and the product quality is getting better and better. At the same time, some new technical problems need to be solved. [0003] In the traditional mode, the workpiece to be processed will be placed on a specific fixture for fixing during the production process. The robot processes the workpiece according to a fixed trajectory. In this process, the walking path of the robot is fixed, and at this time, the position of the workpiece to be processed in the space is required to be fixed. However, in some production situations it is not possible to guarantee the consistency of the positions of the workpieces to be pr...
