Problems solved by technology

[0006] In the current imaging and shooting system, the structure of the light splitting method of a single camera is complex and the volume is too large. The use of gratings or prisms for light splitting is likely to cause loss of light intensity and affect image quality. However, the multi-camera solution has synchronization problems during image synthesis, which is likely to cause image synthesis errors. dislocation

Abstract

The invention relates to the technical field of image processing, in particular to an imaging shooting system and method based on a filter optical wheel, and the method comprises the steps: enabling different areas to enter an optical path in turn in the rotation process of the filter optical wheel, filtering light rays, and dividing the filtered light rays into optical signals with different frequencies to pass through; wherein the optical signals with different frequencies are imaged on the image sensor respectively; and synthesizing the images corresponding to the optical signals with different frequencies to obtain a required image. The filter optical wheel is divided into at least two regions along the circumferential direction, and different regions are respectively subjected to different surface coating and are used for allowing optical signals with different frequencies to pass through. By means of the imaging shooting system and method, optical signals with different frequencies can be filtered through the filter and reach the image sensor to be imaged, and finally the optical signals are synthesized into needed images or videos, so that light intensity loss caused by grating or lens light splitting is avoided, imaging details are increased, the synchronization effect is guaranteed, and the image quality is effectively improved.

Description

【Technical field】 [0001] The present invention relates to the technical field of image processing, in particular to an imaging and shooting system and method based on a filter light wheel. 【Background technique】 [0002] With the development of national economy, video surveillance system, as the core part of the development of security field, has become a necessity to ensure social stability and public and private property security on a global scale. With the development of industry and network, video surveillance related technologies have also made great progress, but the technology of the camera itself still has certain deficiencies. The current popular cameras cannot meet the needs of all-weather and complex lighting conditions. Although digital image processing technology can provide certain supplements and enhancements to the imaging effect of the camera, only the technical upgrade of the camera itself can fundamentally meet various complex lighting conditions. Under t...
