Algorithm of Machine Vision System for Detecting Holes in Furniture Panel
In order to measure the hole position in the furniture panel with the high precision, a machine vision onset detection method was proposed in the paper. After the image denoising which is done by the pixel value filter and distance correlation filter it was adaptive binarized. Then the image is processed by the secondary hole localization algorithm. By fine-tuning the hole position close to the real round hole, it solve the position extraction of common distorted holes and provide support for the progress of circular hole position onset measurement technology. The experiment results showed that using the algorithm in this paper, the average value of 4 056 circular holes in 1 022 furniture panels is 100.05 mm and the standard deviation is 0.041 mm with 5 repetitions. Within the error range of ±0.5 mm, the coincidence degree of the ergonomic measurement of the ,X,-coordinate of the hole center is 99.8%, and the coincidence degree of the ,Y,-coordinate is 92.9%.
