Description

Array type three-dimensional optical image equipment

Technical Field

The present invention relates to an imaging device, and more particularly, to an optical imaging device for obtaining an image by optical ranging.

Background

The imaging of three-dimensional images can be divided into two main categories, static scene shooting and dynamic scene shooting. When a static scene is shot, only one camera is needed to be used, one image is shot at a certain position angle, then the camera is moved in parallel for a certain distance, and then the images are shot, so that a group of three-dimensional images with parallax errors is obtained. When shooting a dynamic scene, a special stereo camera (such as a double-lens camera) is required to be used, or two cameras are required to shoot two images at one time; the existing imaging shooting of three-dimensional images is generally obtained by shooting dynamic scenery through a double-lens camera, the double-lens camera adopts two parallel lenses to capture images simultaneously, when a left image and a right image respectively enter a left eye and a right eye, a stereoscopic visual effect can be generated, and the polarization principle is widely applied to stereoscopic shooting. However, the cost of the dual-lens camera is very high compared to that of a common single-lens camera, and it is difficult to accurately reflect the real stereoscopic effect of the object, so that the finally obtained stereoscopic image deviates from the real object in the proportional size.

Therefore, there is a need for a camera device with better and more realistic stereoscopic effect.
