Abstract

The present invention discloses a photogrametry method based on double panorama. The photogrametry method comprises: 1, acquiring the panorama image stereo image pair of a fixed baseline by using two panorama cameras; 2, acquiring the shooting position and the attitude angle of the panorama image through GPS and IMU; 3, acquiring the coordinates of image points having the same name in the panorama image; 4, acquiring the coordinate correction value of an object point according to a collinearity equation; and 5, determining the coordinate of the object point according to the original value coordinate and the coordinate correction value of the object point. According to the present invention, the pixel coordinate of the object point in the panorama image can be accurately determined by acquiring the panorama image through the two panorama image cameras and by acquiring the coordinates of the pair of the image points having the same name, and the advantages of convenient operation, convenient operation, high accuracy, effective measurement efficient improving and cost reducing are provided.

Description

technical field [0001] The invention relates to the technical field of photogrammetry, in particular to a photogrammetry method based on double panoramas. Background technique [0002] At present, traditional surveying and mapping operations are generally used in aspects such as census of national conditions, geological disaster monitoring, and traffic management. However, most traditional surveying and mapping are performed outdoors, with high labor costs, long operation cycles, and low work efficiency, which cannot meet most measurement needs. Contents of the invention [0003] The purpose of the present invention is to provide a photogrammetry method based on double panorama, which can improve the efficiency of measurement. [0004] To achieve the above object, the present invention provides the following scheme: [0005] A photogrammetry method based on double panorama, said photogrammetry method comprising: [0006] Step 1: Use two panoramic cameras to obtain a ste...
