Double-light shooting system

Abstract

The invention discloses a double-light shooting system, which comprises an optical lens, and is characterized in that a light splitting module capable of splitting light waves transmitted by the optical lens into visible light and infrared light wavelength range light waves is arranged on the imaging side of the optical lens; the shooting system further comprises two photosensitive chips used forreceiving the light signals split by the light splitting module. The shooting system further comprises an image processing module capable of integrating and outputting the light waves received by thephotosensitive chips. The light splitting module is provided with a light splitting inclined plane, and the included angle a between the light splitting inclined plane and the horizontal direction isgreater than or equal to 10 degrees and less than or equal to 60 degrees, wherein the light wave range of the visible light comprises 420 nanometers to 650 nanometers of light waves, and the light wave range of the infrared light comprises 700 nanometers to 1100 nanometers of light waves. According to the invention, high definition of a shot image is realized, the image color reducibility is good,and clear imaging can be realized under low illumination.

Description

【Technical Field】 [0001] The invention relates to an optical system, in particular to a dual-light shooting system. 【Background technique】 [0002] At present, surveillance shooting systems are widely used in people's daily lives. However, the current security monitoring and road condition monitoring systems have the following shortcomings: [0003] 1. The existing shooting system uses a single lens to match a single photosensitive chip. For a single photosensitive chip, the wavelength of the light wave that needs to be received is relatively wide. Therefore, the overall picture definition is not high and the shooting effect is not good; [0004] 2. The existing shooting system uses a single lens to match a single photosensitive chip, reflecting that the wavelength of each color is not well restored on a single photosensitive chip, resulting in the phenomenon that the color of the shooting picture is not full; [0005] 3. The existing shooting system uses a single lens to match a sin...

Problems solved by technology

[0003] 1. The existing shooting system uses a single lens to match a single photosensitive chip. The wavelength of light that needs to be received by a single photosensitive chip is relatively wide. Therefore, the overall picture definition is not high, and the shooting effect is not good;

[0004] 2. The existing shooting system uses a single lens to match a single photosensitive chip, reflecting that the wavelengths of each color are not well restored on a single photosensitive chip, resulting in the phenomenon that the color of the shooting picture is not full enough;

[0005] 3. The existing shooting system uses a single lens to match a single photosensitive chip. In a low-light environment, some wavelengths of light waves cannot be used, resulting in a decrease in the overall light flux and unclear images.
