Description of the Invention: [Technical Field] The present invention relates to an imaging method and system, and more particularly to a dual-source auxiliary imaging method and system capable of obtaining a color image at night. [Prior Art] In recent years, with the further development of multi-pixel multi-pixel monitoring system, the monitoring system has the advantages of random access, high speed, high sensitivity, low power consumption of pixel signals, and the image capturing device of the monitoring system. In the main reference, a CCD (Charge Coupled Device) image sensor is used, and the image capturing principle of the image capturing device is used to sense the reflected light of the object by using a CCD image sensor. The light is converted into an electronic signal, and the collected electronic signals are processed and output to the outside for image processing. The structure of the monitoring system of Xiyou is equipped with an auxiliary light source on the side of the image capturing device, which can be photographed on the object to be photographed. When the image capturing device starts to take a picture, it can be activated with the auxiliary light source to generate a light source, which can assist the photography. The imaging system is integrated with the φ or the image capturing device and the auxiliary light source, and is photographed on the object to be photographed. When the image capturing device starts the image capturing, the auxiliary light source is also illuminated at the same time. The light source of the auxiliary image capturing device is an infrared light source. The wavelength of the infrared light is about 780~1000 nm. This wavelength is a spectrum that is invisible to the naked eye. Therefore, it is not only used when building (4) or traffic monitoring. Hidden will not scare the driver, and can be used at night or when the sky is dim. However, the infrared light source has the inability to effectively recognize the lack of a specific color. If it is used for vehicle monitoring on the parent, such as license plate recognition, the monitoring system 3 201025203 has a low recognition ability ‘the license plate of all colors cannot be effectively recognized. As described above, the embodiments of the present invention are intended to be a breakthrough and improvement of the present invention, that is, to enhance and improve the conventional embodiments. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a dual light source assisted imaging method that achieves color images at night. Thus, the dual light source assisted imaging method of the present invention comprises the steps of: (a) generating a first light beam of a first wavelength belonging to the non-visible wavelength range; and (b) generating a second wavelength that is not of the first wavelength range. a second light beam; and (c) 0 acquiring an image generated by the first light beam and the second light beam. Another object of the present invention is to provide a dual light source assisted imaging system that achieves color images at night. The dual light source auxiliary imaging system of the present invention comprises a first illumination device, a second illumination device and an image capture module, wherein the first illumination device generates a first light beam belonging to a first wavelength in a non-visible wavelength range, the first light beam The second illumination device generates a second light beam that is not the second wavelength of the first wavelength range.

The first illumination device 11 and the second illumination device 12 are light sources combining two different wavelength ranges, and the combination and matching manners thereof are as follows: 1. The first wavelength belongs to an infrared light wavelength range and the second wavelength belongs to an ultraviolet light wavelength. Scope, the advantage of such a light source is that both infrared light and ultraviolet light belong to invisible light, so that it is not easy to be detected when photographing at night, for example, an overspeed vehicle. 2. The first wavelength belongs to an infrared light wavelength range and the second wavelength belongs to a visible light wavelength range.
