Abstract: A method for constructing a real-geographic-space scene in real time based on a panoramic-video technique is provided. By using a measuring robot and the attitude sensors, accurately determining the geographic coordinates and the attitudes of the cameras, where the cameras may be installed in a fixed or stringing manner, where in the fixing type a plurality of neighboring videos at the same moment undergo orthographic correction and splicing, and in the stringing type the cameras are installed to a guiding device and may locally, independently and quickly move and shoot, and the videos of the neighboring cameras are spliced in real time; and fusing the videos, the geographic coordinates and the environment sounds that satisfy the delay time, to form a scene video streaming.

Abstract: mechanical arm type measuring robot device and an application method, and relates to the technical field of intelligent coal mine mining. The mechanical arm type measuring robot device comprises an automatic leveling total station, a protection mechanism, a pitch adjusting mechanism, a yaw adjusting mechanism, a vertical rotating mechanism, a controller, a mounting base and a mobile terminal. Based on a preset pitch angle and a preset yaw angle, the measuring robot starts from an initial position, and performs extension and retraction actions in a plurality of degrees of freedom in the pitch adjusting mechanism and the yaw adjusting mechanism to move the total station to a preset working position.

Abstract: A measuring-robot device for fully mechanized coal mining faces and an automatic measuring system are provided. The measuring robot includes a suspension cage, a total station, a prism and an industrial computer. Firstly, the suspension cage with automatic leveling function is fixed on the top beam of a hydraulic support, then the total station and the industrial computer are fixed in the suspension cage, and finally the prism with a plug connector is installed under the base of the total station, forming a measuring-robot device. According to the fluctuations of the fully mechanized coal mining face, several measuring robots will be deployed along the fully mechanized coal mining face, and the adjacent measuring robots are line of sight to each other, forming the automatic measuring system covering the fully mechanized coal mining.
