Abstract

The invention discloses an imaging frame rate detection system and detection method for a near-infrared camera. The system comprises an illuminating light source, a barcode rotating barrel, a near-infrared camera signal acquisition card, an image workstation, a driving control card and a servo motor. A to-be-detected near-infrared camera is put in an observation area of the barcode rotating barrel, light adjusted through the driving control card is irradiated on the barcode rotating barrel, the servo motor drives the barcode rotating barrel to rotate at a fixed speed, the near-infrared camerasignal acquisition card is capable of acquiring and outputting bright field irradiation barcode information, acquired by the to-be-detected near-infrared camera, on the rotating barrel to the image workstation, and the image workstation acquires barcode information through a code reading program and correctly compares with a standard library. In the process, the rotating speed of the servo motor of the barcode rotating barrel is continuously increased until the to-be-detected near-infrared camera fails to acquire correct barcode information, so that imaging frame rate extreme of the camera isachieved. Imaging frame frequency data can be obtained by calculation according to parameters such as the rotating speed of the servo motor and the size of the barcode rotating barrel, and accordinglyimaging frame rate detection of the to-be-detected near-infrared camera is realized.

Description

technical field [0001] The invention relates to the technical field of imaging frame rate detection, in particular to an imaging frame rate detection system and detection method for a near-infrared camera. Background technique [0002] At present, the imaging frame rate detection of near-infrared cameras is mainly obtained by the user through manual photo collection. Due to the influence of ambient light and sample spectrum, multiple operations have to be performed in order to obtain more accurate data, which is very inconvenient. And waste a lot of research time. However, at present, there is no imaging frame rate detection system for near-infrared cameras available for practical application at home and abroad. [0003] The solution of the present invention is to improve the existing near-infrared camera imaging frame rate detection system for the above problems. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the present inven...
