Embodiment Construction

[0044] refer to figure 1 , the system of the present invention is mainly composed of a camera platform, an angle acquisition and platform control unit and a computer. in:

[0045] The camera platform is composed of a camera, a pan-tilt and two absolute photoelectric encoders. The camera is placed on a fixed pan-tilt with a fixed optical center. It can rotate from 0° to 360° and pitch to plus or minus 90°. The camera transmits the collected real-time video data to the computer and the angle acquisition and platform control unit, and two absolute photoelectric code discs provide the rotation angle and pitch angle of the camera respectively.

[0046] The angle acquisition and platform control unit is composed of a single-chip microcomputer, a serial port and a synchronization signal separation chip. The synchronization signal separation chip separates the frame synchronization signal from the video information and transmits it to the single-chip microcomputer. The single-chip micro

Abstract

The invention discloses a geographic information guide method and a system based on augment reality, which mainly solves the problem that the existing map-type geographic information guide method has poor intuition and needs to identify geographic direction. The guide method of the invention is as follows: firstly, collecting a plurality of images from different angles, and determining the projection coordinate of a target space point on a specified initial image plane by geometric calculation; secondly, accurately determining the coordinate of the target space point in a real-time video by geometric calculation on the basis of the projection coordinate of the target space point on the initial image plane and the real-time angle information of a camera; and finally, overlaying virtual geographic information at the position of the target space point in the real-time video, and fusing the virtual geographic information and real scenes in the video through video treatment, thus ensuring the target to be more visual and intuitive and easier to be identified by people. The invention has the advantage that the virtual geographic information provided by the invention is intuitive and effective, and the invention is applicable to places requiring geographic information guide.
