Abstract


The stability of the system is an important part of modern weapons systems operational platforms , the core has always been the weapon system design . Stable performance of the system under the environment of complex battlefield , a direct impact on the viability and operational effectiveness of the entire weapon system on the battlefield . Therefore , system design , system stability performance requirements and testing has become an important part of the R \u0026 D and design of the weapon system . Design a stable system detection device based on digital image processing , high-precision detection of the posture angle of the weapon barrel under complicated conditions . The main contents are as follows: First, the methods and techniques of the related high - precision angle measuring , and the angle of the actual analyte analysis , based on this system architecture design is carried out according to the system specifications . Second, structural design , in order to solve the vertical problems of the initial state of the system , using a high-precision optical equipment . And the design and selection of the image processing part of the system hardware , including processors , capture cards , storage devices . Again , in order to get at the same time has a higher signal-to-noise ratio and clear high frequency edge of the image , wavelet - based neighborhood threshold denoising method based on Bayesian locally adaptive threshold , and in accordance with the subject actually gives a wavelet the threshold function improved method . Finally, in order to accurately strike the centroid of the light spot image , the text in the image after the noise reduction image segmentation. Higher accuracy of segmentation based on wavelet theory modulus maxima edge detection method for image segmentation . Analysis of the impact on the overall error of each part of the system .
