In the paper, a method based on the speeded up robust features (SURF) algorithm is presented for the seabed relief image matching navigation. By using of high-resolution features of the side-scan sonar image, the effective algorithm of image processing, SURF, is introduced to side-scan sonar seabed relief image processing for underwater navigation application. According to the characteristics of underwater...
According to the current status of water level monitoring of inland river, this paper presents and designs a multi-sensor integrated dynamic system for mobile water level measurement, which is based on CORS(continuous operational reference system) GPS(global positioning system), GPRS(general packet radio service), PDA(personal digital assistant) technology as well as a post processing platform. The...
Based on the current situation of underwater navigation, this paper presents an underwater topographic matching navigation method which is the integration of TERCOM and MCTM algorithm. First of all, we use the TERCOM to acquire a rough position of vehicle. Secondly, a search area is found according to TERCOM positioning result. The multi-contour matching algorithm is implemented in the area. The algorithm...
This paper presents a new method to fulfill the contour match of seabed topography through image match algorithms. Firstly, the generation of topographic contour image is studied. Then, the theory of image matching is introduced. Based on above, a complete matching process is given out. Finally, a positioning experiment is implemented by means of contour image match. Positioning accuracy is better...
