The invention discloses a spiral-orbit type auxiliary system for structural distortion shooting measurement. The auxiliary system comprises a fixed support and a spiral orbit suspended on the fixed support by a fixed steel wire rope. A drive system for driving the orbit steel wire rope extending along the spiral orbit is fixed at the bottom of the spiral orbit; a counterweight system connected by the orbit steel wire rope is arranged at the top of the spiral orbit; a motion platform that is dragged by the orbit steel wire rope is arranged on the spiral orbit; and a photographing holder is fixedly connected to the motion platform. The drive system drives the orbit steel wire rope to drag the motion platform and the photographing holder to move on the spiral orbit, thereby realizing alternately or continuous shooting by a camera of the photographing holder by aligning at a measured structure during the motion process. With the system, the shooting height is increased effectively and the coverage range of camera shooting is extended; alternately or continuous motion shooting of the camera is realized; and the work efficiency of structural distortion shooting measurement is improved substantially.
Description
technical field [0001] The invention relates to a photogrammetry auxiliary system, in particular to a spiral orbit type photogrammetry auxiliary system, which can be used for auxiliary measurement of structural deformation and belongs to the field of photogrammetry systems. Background technique [0002] In service, flexible structures will be deformed due to the influence of aerodynamics, vibration, impact, and heat. The structural performance after deformation often fails to meet the expected goals. To compensate the structural performance, it is usually necessary to measure the deformation of the structure first. Due to the advantages of high precision, fast measurement speed and simple measurement equipment, photogrammetry technology is widely used in structural deformation measurement. In photogrammetry, in order to obtain satisfactory measurement results, it is necessary to take a large number of photos of the measured object from different angles. However, in the exis...
