Energy-efficient data gathering is a common but critical operation in many applications of wireless sensor networks. Clustering is a kind of key technique used to reduce energy consumption, which can decrease the communication load and prolong the network lifetime by means of similar data aggregation in the cluster-heads. In this paper, we propose a novel clustering algorithm which better suit the...
According to the calibration of binocular vision, an improved two-stages camera calibration method involved with multi-distortion coefficients is introduced in this paper. It takes the sum of distance in the world coordinate between ground truth 3D points and calculated 3D points as cost function which is optimized by evolution algorithm (EA). The 3D pointspsila coordinate are calculated by the imitated...
Stereo-vision plays an important part in planetary exploration. A high-precision calibration method is introduced for such system, which uses wide-angle lens. It makes use of planar homography constraint to estimate intrinsic and extrinsic parameters. On the basis of this initial guess, an optimization scheme is used to minimize a new cost function, 3D reprojection error sum. All calibration parameters...
