Abstract

The invention discloses an image-analysis-based excited fluorescence peroxide detection device and a detection method thereof. According to the invention, a to-be-detected substance reacts with a detection wafer; after excitation light makes irradiation, fluorescence is generated; an image acquisition device shoots an image of the detection wafer, collects the image, and transmits the collected image to an image processing circuit; the image is processed to obtain to-be-detected substance difference values of R, G and B; and the to-be-detected substance difference values are compared with detection limits of the R, G and B to determine whether the to-be-detected substance is peroxide or not. The device has a simple structure and rapid detection of peroxide can be realized; only the CCD industrial-grade camera is needed for shooting and then images are processed and changes of the detection wafer before and after to-be-detected substance detection can be detected to determine whether the substance is peroxide. Moreover, the method has a simple idea; and rapid detection as well as trace detection can be realized.

Description

technical field [0001] The invention relates to the field of detection of dangerous explosives, in particular to an image analysis-based excited fluorescent peroxide detection device and a detection method thereof. Background technique [0002] With the emergence and application of new explosives, the pressure on anti-terrorism is also increasing, and at the same time, it poses a great challenge to the security system of public places. The new type of peroxide explosives is difficult to achieve non-contact detection due to its own characteristics. [0003] Aiming at this phenomenon, a variety of explosive detection technologies in recent years have been investigated and analyzed, and the main technical characteristics of existing products are found as follows: [0004] (1) Ion mobility spectrometry technology, representative products include Smith IONSCAN series products in the United States. It is an atmospheric pressure analytical chemistry method to detect and identify ...
