A stereoscopic lens for an ordinary camera or video camera

Abstract

The present invention is a stereoscopic lens added in front of the lens of a common camera (or video camera), and is used for obtaining binocular stereoscopic images. Compared with the conventional additional stereo lens, the viewing angle range of the camera (or video camera) can be maintained while reducing the size and weight of the additional lens. The present invention adopts two groups of optical assemblies corresponding to the left eye optical path and the right eye optical path of binocular stereoscopic imaging, each optical path includes a diverging lens (or lens group), a rhomboid prism (or a mirror group composed of two plane mirrors) , Splicing and converging lenses (or lens groups), to achieve compressed viewing angle, parallel light transmission, translation, widening viewing angle, left and right image splicing, and finally realize the splicing of the two images of the left eye optical path and the right eye optical path into one image, and then enter the camera ( or camera) to obtain an image containing stereoscopic information.

Description

technical field [0001] The present invention relates to the field of stereo photography, in particular to binocular stereo photography and imaging equipment, utilizing existing single-lens photography equipment or systems (such as ordinary cameras, ordinary video cameras), by adding an additional device (i.e. an additional stereo lens) in front of the lens to obtain Binocular stereo imaging information. Background technique [0002] Stereo photography is a photographic method that expresses the three-dimensional space of the scene. By shooting two images from different viewpoints, simulating binocular viewing to achieve a three-dimensional effect. The shooting tools of stereo photography include special stereo cameras (or stereo cameras); there are also stereo attachment mirrors assembled on single-lens cameras (or single-lens cameras); there are also two (or more) single-lens cameras (or single-lens cameras) Carry out transformation, make two equipments shoot synchronously...

AI Technical Summary

Problems solved by technology

[0003] Using a stereo camera (or stereo camera), the imaging effect is good, but the equipment cost is high, and the versatility with traditional photographic (or video) equipment is poor; two (or more) single-lens cameras (or single-lens cameras) are used for transformation, imaging The effect is good, but the equipment cost is high, the system is complicated, the volume and weight are large, and the portability is poor, and it is difficult to realize the synchronization of two devices. The method of moving the ordinary camera (or video camera) left and right is used for shooting, and the control of the moving distance and shooting angle It is very difficult, and the shooting time is not synchronized, and the imaging effect is poor
