Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Referring to Fig. 1, a method for detecting the profile of a metal bonded diamond with complex profiles, the detection method uses a CCD high-power camera to collect images of aluminum sheets ground by a grinding wheel, and then denoises the images through a matlab algorithm, and uses The canny operator performs edge detection on the image, and finally compares the design drawing with the image obtained by edge detection to detect the grinding wheel shaping in real time.

[0015] Further, the specific process of denoising includes: first filtering the salt and pepper noise in the image by median filtering, and then filtering the Gaussian noise in the image by adaptive wiener2 filtering.

[0016] Median filtering is a nonlinear signal processing method, which can overcome the blurring of image edges brought by linear filtering such as least mean square filtering ...

Abstract

The invention relates to a diamond outline model detection method of complex surface metal bonding, carrying out image acquisition of wheel grinded aluminum sheet by CCD high-power camera, then denoising the image with matlab algorithm, and performing edge detection of the image with canny operator, finally comparing the design drawing with the image obtained from the edge detection and realizing real-time detecting of grinding wheel truing condition. The invention provides a complex surface metal bonding diamond outline model detection method possessing the characteristics of good rapidity and low cost.

Description

technical field [0001] The invention relates to a profile detection method. Background technique [0002] In the Elid (on-line electrolytic dressing) form grinding process, the profile of the metal bond diamond grinding wheel has a direct impact on the grinding effect, so the detection method for measuring the profile of the metal bond diamond sand on complex profiles is very important. [0003] General sand profile detection methods include laser detection technology and ultrasonic detection technology, but these technologies cannot meet the requirements well due to their own limitations. For example, the laser detection device is expensive, and the ultrasonic method needs to remove the surface oxide film. This has caused these detection techniques to be unable to detect the sand profile quickly and economically. Contents of the invention [0004] In order to overcome the shortcomings of slow speed and high cost of the existing sand profile detection method, the present ...
