    摘要: A three-dimensional map-generating apparatus and method using structured light. The apparatus for generating a three-dimensional map using structured light includes an odometer detecting the pose of a mobile robot, and a distance-measuring sensor including a light source module that emits light upward and a camera module that captures an image formed by light reflected from an obstacle, and measuring a distance to the obstacle using the captured image. The apparatus measures a distance to the obstacle using the distance-measuring sensor while changing the relative pose of the mobile robot, thereby generating a three-dimensional map.

    摘要: A three-dimensional data matching system is disclosed. Data matching is performed by merging distance information and image information. Therefore, matching accuracy is improved even if a sensor with relatively low sensitivity is used. Matching data generated as a result of matching range data and CAD data is projected onto an image captured by a camera, an effective edge is extracted from the image, and an error of the matching data is corrected based on the effective edge, thereby improving matching accuracy.

    摘要: A method of correcting an error in a transport stream (TS), and a digital broadcasting receiving method are provided. The TS is transmitted from a physical layer. It is determined whether a pointer included in the TS has an error. The pointer is corrected if it is determined that the pointer has an error. It is determined whether a frame buffer value is correct. The frame buffer value is corrected if it is determined that the frame buffer value is not correct. In the TS error correcting method, a pointer error or an erroneous frame buffer value existing in a TS is corrected before the TS is transmitted to an upper layer (e.g., a link layer), and IP data can be transmitted to the upper layer. Accordingly, performance degradation due to Doppler shift can be addressed.
