Device for testing torsional angle of mast system based on high speed camera and design method thereof

Abstract

The invention relates to a device for testing the torsional angle of a mast system based on a high speed camera and a design method thereof, belonging to the field of image testing. The method comprises the following steps: fixing two high-energy lasers at the top of a tested mast system at a certain interval, so that the laser beams emitted from the high-energy lasers are respectively irradiated on an imaging plate arranged on a base so as to form two circular light spots; simultaneously, acquiring an image on the imaging plate in real time by the high speed camera, and extracting the central positions of the two light spots in the image; and in the process of lifting the tested mast system, twisting the two high-energy lasers with the tested mast system, recording the positions of determined initial lines of the light spots and the positions of real-time lines of the light spots in the process of twisting by the high speed camera, and calculating the torsional angle of the tested mast system. The device can test the torsional angle of a mast lifting system in a scout car, and has the advantages of high precision, good real-time property, and electricity saving and reduction of cable connections.

Description

technical field [0001] The invention relates to a high-speed camera-based mast system torsion angle testing device and a design method thereof, belonging to the technical field of image testing. Background technique [0002] The mast lifting system plays an important role in the reconnaissance vehicle. During the process of raising the mast lifting system from the lowest to the highest, due to the gap in the mast guide rail or structural deformation, there will be a certain torsional deformation angle under the action of load or wind. The parameter is the key parameter of the mast lifting system, which is directly related to the accuracy of the reconnaissance system, so how to test this torsion angle with high precision is very important. Since the lifting height of the mast can reach nearly 8m, and the torsion angle is different at different heights, this angle cannot be measured by directly installing an angle sensor. There is no test device to detect the torsion angle of ...
