Background

Drug detection is an essential step in drug inspection work. After the drug addict takes or injects drugs, the corresponding drugs remain in the urine within a certain time. Therefore, the drug absorption condition can be quickly discriminated by detecting the drug content in the urine. The multi-in-one urine cup is internally provided with a plurality of test strips aiming at different drugs and clings to the transparent circumferential wall of the urine cup. After urine is injected into the urine cup, the test strips react with the urine, and each test strip presents different colors according to whether the urine contains related drugs or not. Human eyes can judge colors individually, so that misjudgment is easy to occur and disputes are caused, and therefore, a urine cup detector is adopted to identify the reaction result of the test strip. The principle of the urine cup detector is that light irradiates the test strip on the urine cup, then the test strip is photographed through a camera, and the picture is subjected to image processing and algorithm analysis by a computer system, so that a detection result is obtained finally.

The first technical scheme is as follows: in order to see the test paper in the urine cup from the outside of the urine cup, the urine cup is made of transparent plastic, the detector needs to be illuminated when reading the urine cup, if the angle or the mode of light is not proper, the light is easily reflected by the mirror surface of the urine cup wall, light spots or halos appear on the picture, and the color recognition of the test paper by the detector is seriously influenced. Therefore, the mounting and position of the optical device is critical.
