Research On Moving Parameter Image Measurement Technology Of Space Multi-object

Computer vision is the method to acquire the 3D space information of objects by multiple images. The existing computer vision technology mainly uses the complex camera calibration to realize survey, the measuring accuracy is decided by the precision of camera calibration, and not easy to control, operates complex in the practical application.The dissertation use computer vision technology characteristic to establish two kinds of novel simplified measurement systems, which is suitable to survey spatial static goal and dynamic goal, has realized the automatic measure by image processing technology. The measurement systems of this dissertation do not need the complex camera calibration, and have characteristic of low requirements for measuring position, simple, high precision, high stability, wide application scope.First,the binocular stereo vision measurement systems are studied in dissertation, two kinds of novel simplified dual-camera measurement systems, namely one system in which dual-camera measurement system of vertical camera axes'surface and the other in which excellent dual-camera measurement system, is proposed and the corresponding mathematic model is established. Second, the camera calibration methods and the establishment method of calibration points are studied in detail. Second, a calibration module is proposed, base on the characteristic of calibration pole and calibration template, which has stable location among points, and is suitable to the requirements of existing calibration algorithm, at the same time it is simply in using.Third, image feature detection technology and feature matching technology is studied in dissertation.The last, The dissertation test the dual-camera measurement system which has vertical surface of cameras axes is right by measuring the space points coordinates of building; test excellent dual-camera measurement system is right by measuring the space points coordinates in building and measuring speed and path of space multi-target; test the measurement can satisfies of measurement requirement of parameter for space moving multi-target by the experimental results.
