The Study Based On Digital Image Processing Technology Of Multi-Barrel Parallelism Measuring Of The Multi-Barrel Rocket Launcher

The paper presents in brief the measurement system project design on Multi-barrel Parallelism of the long-distance Multi-barrel Rocket Launcher and emphasizes on the digital image processing part.According to the actual work environment and the request of technique index , the laser collimation matched digital image processing technique are adopted to realize the measurement of Multi-barrel Parallelism in this system project .In order to validate the feasibility of this project ,this paper contrives a few principles experiments and gives forth an algorithm suite . The light spot image thresholding part of the suite puts forward the iterative algorithm to gain the best threshold by comparing, which could perfectly hold the original image feature .In the extracting the light spot image features part, the algorithms on calculating the coordinates of the "energy distribution barycenter" in the 256 gray levels image and the "geometric-center" in the binary image are adopted respectively and so on. The experimental results show that the request of the measurement precision can be satisfied in this measurement project.
