Camera fixing rack and camera fixing device

Abstract

Provided are a camera fixing rack and a camera fixing device. The camera fixing rack comprises a first supporting shaft, a first rotary sleeve, a second supporting shaft, a second rotary sleeve and a mounting base, wherein a first boss portion is formed at one end of the first supporting shaft; the outer circumference face of the first boss portion is rotationally sleeved with the first rotary sleeve; the second supporting shaft is fixed to the first rotary sleeve; the axis of the first supporting shaft is perpendicular to the axis of the second supporting shaft; a second boss portion is formed at one end of the second supporting shaft; the outer circumference face of the second boss portion is rotationally sleeved with the second rotary sleeve; and the mounting base is fixed to the second rotary sleeve and used for mounting of a camera. By means of the camera fixing device, the shooting orientation of the camera installed on the fixing rack can be adjusted by various angles, installation is convenient, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of an automobile collision test, in particular to a fixing frame and a fixing device for fixing a high-speed camera in the automobile collision test. Background technique [0002] With the advancement of science and technology, cameras are more and more widely used. In order to obtain accurate test image records during automobile crash tests, high-speed cameras need to be fixed on a fixed frame for image recording. While the fixed frame firmly fixes the high-speed camera, it also It is necessary to meet the requirements of crash tests for different viewing angles of high-speed cameras. [0003] In the preparation stage of vehicle collision, engineers usually confirm the position acquisition of safe falling video angle images through the requirements of the test program. Because the planning of the test collision area is not too perfect, the shooting position of the camera often changes in the position of th...

[0004] When recording the images of the parts at the bottom of the test vehicle and the unchaining of the traction block, because in the crash chamber test, the purchased camera frame is used to collect the video of the test, which is only suitable for large-scale image collection. Partial collection is a bit lacking, and different test requirements cannot be fulfilled with different lenses alone. It is very inconvenient to collect video on the camera stand to safely fall off the bottom of the mule cart. A certain height, a certain projection range, a certain horizontal position and a certain degree of clarity They are all very lacking. It is a very unprofessional image positioning just by taking the camera out of the camera frame to collect images on the ground, and the camera effect is not the best.
