Abstract

It is a grinding wheel appearance dynamic measurement method based on image identification in the measurement technique field, which is first to capture and store the transient image of the grinding wheel in fixed position and to photograph the image which is input into the computer, wherein, the sync control card sends signals to the computer to let it freeze the image to realize the dynamic capture; second to realize the fringe positioning of the image with high accuracy and it adopts the method based on local curved surface plug value and sample couple to position the image fringe on the sub-picture element degree.

Description

technical field [0001] The invention relates to an online detection method based on image recognition, in particular to a dynamic detection method of grinding wheel shape based on image recognition. For use in the field of measurement technology. Background technique [0002] In modern mechanical processing, grinding has high processing accuracy and directly affects the final quality and performance of the product. The wear condition of the grinding wheel affects the quality of the grinding process to a large extent. At present, there is still a lack of reliable and general indicators and mathematical descriptions for evaluating the wear degree of the grinding wheel. It is difficult to obtain a good grinding effect only by the experience of the operator. Big. Some on-line detection and monitoring technologies of grinding wheels in the grinding process have also been proposed in China, such as the use of acoustic emission sensors and power sensors to jointly monitor the gri...
