Abstract
The utility model relates to a testing device for the night vision function of a camera. The testing device comprises a square frame body and an H-shaped support, wherein two upper end parts of the H-shaped support are in hinged connection with the middle parts of two lateral sides of the square frame body respectively. Four groups of positioning grooves which are vertically symmetrical are vertically mounted on two vertical rims and vertical partition boards of the square frame body of the testing device, and six blocks of image plate targets can be placed simultaneously, thus reducing the time for frequently replacing the image plate targets. The square frame body and the H-shaped support of the testing device are in hinged connection with each other so that the angles between the image plate targets and an optical axis of the camera can be effectively adjusted. Dark-light treatment is carried out on the surfaces of the square frame body and the H-shaped support of the testing device so that the light reflection phenomenon can be effectively avoided. Support legs and vertical rods of the testing device can rotate left and right, and the support legs and the square frame body can be arranged in parallel after the test is completed, thereby effectively reducing the occupied space of the testing device.
