Using the combined weighting method and the super‐efficiency Slack‐Based Measure (SBM) model, this study evaluates urban‐rural integration and land‐use efficiency across 30 provinces in China. Additionally, we explore the coupling and coordination relationship between them. The results show that the overall urban‐rural integration level and land‐use efficiency in China from 2010 to 2019 are not high...
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...
In this paper, a method for side scan sonar image matching is proposed based on SURF and similarity calculating in typical areas. The process is composed of three steps of rough matching, geometric correction and accurate matching. Firstly, rough matching is implemented to get a rough matching relationship of reference image and matching image based on SURF. Then geometric correction is executed with...
