Amming at the problem of poor manual measurement consistency,the low efficiency and low machine vision measurement accuracy of L-angle gap installed on the swing cap of a certain type of armor breaking projectile,a machine vi-sion composite detection method based on SVM multi-feature fusion template matching location and NMS-OTSU non mini-mum suppression algorithm for extracting the edge feature of gap are proposed,which realizes automatic identification,loca-tion and accurate measurement of L-angle gap.The experimental results show that the proposed algorithm can locate the gap area and detect the gap width of 0.05～0.3mm accurately,and the measurement error is less than 0.02mm.The proposed method realizes accurate measurement of L-angle gap under current complex working conditions,and meets the needs of ac-tual automatic assembly production.
