Research, Vision-related Issues Based On Video Total Station

Recently, the computer vision has been developed rapidly of which the products have been widely applied in the all departments of the industry. It is important to reasonable introduce the computer vision into the survey.In this paper, a piece of hardware-video total station has been devised which combined CCD camera with the total station .And it makes full use of the virtues of the computer vision and the points positioning technology of total station. Based on video total station, the studies on the fields of the computer vision are included. The mostly works are listed as follow.1. The design of video total station. For reasonably making use of the virtues about the computer vision and the survey, through the necessary proof in the theory, a piece of hardware-video total station instrument has been devised by the way of the building block which has been provided with the high precision of point measure and the surface measure.2. The pretreatment of image. The contrast of the image has been improved by the contrast-enhancement based on which the characteristics in the image have been picked up by the means of the Moravec and the SUSAN arithmetic. And that, the merits and flaws are listed.3. Systemic study on the camera calibration. The traditional calibration and the self-calibration are included.4. The study on the image matching. The matching ways in common use have been summarized. There are single scale matching,multi-scale matching and the whole self-adapting matching. The result is that the self-adapting way is better than the others obviously which has better precision.
