Abstract

The invention relates to a method and system for fast full-field detection of grinding wheels in place based on a line array camera. It utilizes the working principle of the line array camera and through a transmission mechanism, has both single-stage drive transmission and a control system with simple logic and can be fast and accurate. Obtain the two-dimensional morphology of the entire surface of the grinding wheel, such as the area, particle size, spacing between the abrasive grains, the density distribution of the grinding wheel abrasive grains, the coordinates of the single abrasive grain in the entire field, and determine whether the abrasive grains have fallen off. , and two-dimensional information such as shedding coordinates. The invention is particularly suitable for in-position detection of grinding wheels, completing operations such as automatic focusing, calibration, image acquisition, analysis and statistics, and is easy to use. Moreover, the system described is lightweight and highly maneuverable. The present invention can also be used for other movable objects to be detected; in the system of the present invention, the offline detection platform can be implemented as an independent structure and can be replaced by other movable objects to be detected, so that the surface detection of other objects can be realized. Full-field detection of dimensional topography.

Description

technical field [0001] The present invention relates to the field of detection of two-dimensional topography on the surface of grinding wheels, more specifically, to a fast full-field detection method for in-position grinding wheels based on a line array camera, and a fast full-field detection system for in-position grinding wheels based on a line array camera . Background technique [0002] The two-dimensional shape detection method of the grinding wheel can obtain various two-dimensional shapes of the grinding wheel for guiding production. In the prior art, methods for detecting the two-dimensional topography of the grinding wheel surface with different implementation principles are disclosed, mainly as follows: [0003] 1. Contact pin method [0004] The stylus method is usually divided into inductive and capacitive. When working, the stylus moves up and down with the shape of the grinding wheel, resulting in a change in the inductance of the inductive sensor. The circu...
