Research of Digital Image Processing Technology of Photoelectric Theodolite’s Target Based on MATLAB

Digital image processing is a technique to digitized image data,which is also called computer image processing. Modern technology keeps digital image processing evolving and expands the application scope. Because of the complexity of the sea scene, as well as the the characteristics of the photoelectric theodolite, the background of uneven homogeneity can be occured in the measured images over the time, and various kinds of clouds and other complex backgrounds may appear a because of the changing weather. How to suppress the diverse backgrounds, enhance the contrast and improve the target extraction ability are the key to successfully capturing the tracking target. This paper takes the processing operation of edge detection and pseudo-color processing. Meanwhile, an improved K-means clustering method is proposed; different kinds of clusters were selected for different kinds of images and realized the rapid and effective image segmentation. The clear edge and detail of image can be realized after the abovementioned operations. In this paper, the processing algorithm of the theodolite image has advantages and disadvantages,the corresponding algorithm can be taken according to specific requirements in practical application, which can be technical reference for the image target recognition and feature extraction.
