Camera shooting equipment and camera shooting method for automobile collision test

Abstract

The invention discloses camera shooting equipment and a camera shooting method for an automobile collision test. The equipment comprises a plurality of high-speed cameras, an automatic aligning mechanism and a control mechanism; the automatic aligning mechanism comprises a guide rail, and an automatic positioning device which is matched with the guide rail and bears the high-speed cameras; the guide rail is arranged on one side of an automobile running track; the automatic positioning device comprises a traction component and a plurality of cantilevers; the traction component is connected withthe cantilevers; the cantilevers are in sliding connection with the guide rail; the cantilevers bear the high-speed cameras; and the control mechanism automatically controls the positions of the cantilevers on the guide rail according to automobile models, so that the high-speed cameras can be automatically positioned, and comprehensive shooting of the automobile collision test is carried out. For different automobile types and different automobile collision test types, the automatic aligning mechanism is remotely controlled through the control mechanism in the camera shooting equipment, so that the positions of the used high-speed cameras can be subjected to batch and coaxial automatic alignment, and the consistency of the shooting ranges of the high-speed cameras for the same automobilemodel in the same test type is ensured.

Description

technical field [0001] The invention relates to the field of automobile collision tests, in particular to an imaging device and an imaging method for automobile collision tests. Background technique [0002] At present, in the field of vehicle safety evaluation in China, according to CNCAP2018 regulations, 9 external high-speed cameras are required to obtain information such as the moment of vehicle collision - 10ms to 410ms, changes in body structure, motion posture of dummy, and working status of the restraint system. In the test development stage, it is necessary to conduct two tests on the same model and the same type of crash test to compare the similarities and differences of information such as the change of the body mechanism at the moment of collision, the movement posture of the dummy, and the working status of the restraint system in the position of the high-speed camera at the same position. Therefore, there are clear and strict requirements for the positioning a...

AI Technical Summary

Problems solved by technology

[0010] In summary, there are many problems in the traditional working method: to adjust the range of high-speed cameras according to regulations, a total of 72 degrees of freedom need to be adjusted

Even if there is an operation manual, there is a great risk of error in manual operation, and it is difficult to guarantee the consistency of the shooting range of the same camera in the two comparison tests

Affect vehicle safety assessment

And manual adjustment is time-consuming and labor-intensive, and there will be safety hazards for engineers on site
