<p>A multi-spectrum coupon quality testing method and system, comprising: collecting a white light image and an infrared light image of a coupon to be tested, and extracting the characteristic information group of the white light image and the infrared light image (101); according to the characteristic information group and the corresponding data of a standard characteristic information group, calculating a relative distance as a quality parameter of the coupon to be tested (102); determining whether the quality parameter is greater than a preset value (103); if yes, then the quality of the coupon to be tested satisfies the usage requirement, and if not, then the quality of the coupon to be tested does not satisfy the usage requirement. The method and system can simultaneously test the surface characteristics, and texture and thickness characteristics of a coupon to be tested, thus avoiding the problem in the prior art of great deviation in test results caused by the use of a single spectrum for coupon quality testing.</p> |
