Abstract

The invention relates to the technical field of aerial photography, and discloses an aerial photography camera imaging time measuring device. The device solves the problems that errors exist in imaging time measurement and the data accuracy of photos is easily influenced. The device comprises a base plate, a photography camera is installed at the top end of the base plate, fixing plates are symmetrically installed on the two sides of the photography camera, the fixing plates are fixedly connected with the base plate, a top plate is mounted at the top ends of the fixing plates, an imaging time measuring mechanism is mounted in the top plate, and a view adjusting mechanism is mounted at the bottom end of the top plate. In the working process, a receiver receives the current starting time, and after shooting is completed, a spring moves upwards, so that a connecting contact on the spring is separated from the contact, the current flowing through the current sensor disappears, the current sensor cannot transmit a signal to the receiver at the moment, the signal disappearing time is recorded, and the imaging time is calculated, so that the accuracy of the photo POS data is improved, and the precision of aerial survey equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of aerial photography, in particular to an imaging time measurement device for aerial photography cameras. Background technique [0002] UAV aerial photography technology is an emerging surveying and mapping data acquisition technology, which obtains 3D results on the ground through preset ground control points, high-overlap photography of UAVs, and post-air triangulation calculations. Among them, the layout of ground control points is time-consuming and laborious, which limits the progress of UAV mapping projects. How to deploy fewer control points and realize image-free control is an important topic concerned by the surveying and mapping industry. In order to realize the image-free technology, it is necessary to obtain accurate pos data (coordinates and attitude data) of the photo at the moment of imaging. The more accurate the photo pos data is, the fewer control points are required, and a larger scale ...
