In order to improve the accuracy of one hand shoulder shooting,it is necessary to detect one hand shoulder shooting.Therefore,the laser displacement detection technology of one hand shoulder shooting based on laser image analysis is proposed.Collect image and study the distribution of the vital feature points of the image,and carry out the laser image feature analysis and displacement detection processing of one hand shoulder shooting action.Based on the feature mark method,the laser feature analysis and map feature detection of one hand shoulder shooting action are carried out.Combined with the fuzzy image displacement detection technology,the feature analysis of one hand shoulder shooting action is carried out.The edge contour feature detection method is used to analyse the laser stripe map.The error correction and compensation processing of laser displacement detection is carried out according to the optical resolution characteristics,combined with the shape characteristics.Sign distribution is used to detect the laser displacement of one hand shoulder shooting.The simulation results show that the spectral resolution of the laser displacement detection of one hand over shoulder shot is good,and the estimation accuracy of displacement parameters is high.The maximum detection accuracy has reached 100%,the error is low,and the minimum can reach 1%.Moreover,the detection time is lower than the other two methods,which is no more than 2 seconds,which effectively realises the action correction of one-handed shoulder shot High shooting accuracy.
