Image Process Technique Based On Shell Body Exterior Surface Flaw Detection

Shell body exterior surface flaw detection system belongs to the application research of intelligent detection technology. It is a kind of auto lossless detecting which applied computer image processing technique to realize high precision and high efficiency. This special system can carry out detection as springing the smooth level of body exterior surface, carries out detection and analysis for the various cuts that surface causes because of the reasons such as production technology, is to determine shell to use the important means of safety.The paper has introduced the overall structure,.principle and design idea for software of this whole intelligent measurement system. While having discussed the image pretreatment method of traditional use in workpiece flaw detection , have put forward based on wavelet transform edge detection pretreatment technology. By qualitative contrast between this two methods, explain wavelet transform edge detection algorithm detects the image that have edge distinct, fine, fight to chirp performance strong etc. besides, through trailing and distill for the flaw image after pretreatment, line draft join etc. processing method, can realize the quantitative analysis for the physical features such as length and the location of flaw.
