Abstract

The invention relates to a linear array camera-based in-place grinding wheel quick full-field detection method and system. According to the method and system, on the basis of the working principle ofa linear array camera, and by means of the single-stage driving transmission of a transmission mechanism and the simple logic of a control system, the full-field surface two-dimensional form of a grinding wheel can be obtained accurately and fast, for example, two-dimensional information such as the area and particle size of single abrasive grains, intervals between the abrasive grains, the density distribution of the abrasive grains, the coordinates of the single abrasive grains in a whole field, information indicating whether the abrasive grains fall off, and the fall-off coordinates of theabrasive grains can be obtained. The method and system of the invention are particularly suitable for the in-place detection of the grinding wheel, can complete operation such as auto-focusing, calibration, image acquisition, analysis and statistics, and are convenient to use; the system is lightweight and has high maneuverability; the method and system of the invention can also be applied to other movable objects to be detected; in the system of the present invention, an offline detection platform can be implemented as an independent structure, and can be replaced with the other movable objects to be detected, so that the full-field detection of the two-dimensional forms of the surfaces of the other objects can be realized.

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...

However, the acoustic emission method cannot obtain complete two-dimensional shape information of the grinding wheel.

[0015] In addition to the above representative methods, there are other detection methods for the two-dimensional information detection method of the surface topography of the grinding wheel. Through the analysis and comparison of various measurement methods, various detection methods have their own advantages and are also There are their own problems, such as the detection speed is too slow, the rapidity cannot be satisfied, the complete two-dimensional information of the X-Y axis cannot be obtained, and the wear particle density is not easy to calculate
