360-degree cylindrical real-time imaging device

Abstract

The invention provides a 360-degree cylindrical real-time imaging device. The 360-degree cylindrical real-time imaging device comprises a wide-angle camera shooting device, a lens set, an optical sensor and a signal processor. The wide-angle camera shooting device is provided with a camera lens, the camera shooting angle of the camera lens at least can form a 360-degree ring, and the ring has a certain width. The structural shape of the camera lens is slightly similar to a hemisphere, and the section radian of the camera lens is larger than 180 degrees. The lens set is used for obtaining appropriate parallel light. The optical sensor receives light from the lens set, converts the light into current intensity of different pixel points on the plane and converts the current intensity into digital signals. The signal processor is connected with an internal storage, reads shot 360-degree cylindrical images in the internal storage and corrects the 360-degree cylindrical images respectively so that the images which are originally distorted by the camera lens can be restored into images approaching solids. One 360-degree cylindrical image can be obtained through processing and is just like an image viewed by a viewer who stands at the center point of the camera lens and rotates by 360 degrees.

Description

technical field [0001] The invention relates to image processing, in particular to a real-time imaging device for a 360-degree surrounding field. [0002] Background technique [0003] Generally, surrounding field images have been widely used in security surveillance systems or surrounding environment image recording, because surrounding field photography can make viewers not limited by viewing angles, but can understand the entire surrounding situation, which is more common Examples of use are security or online house inspections. In these examples, surround photography can help viewers understand the actual situation without being deceived by the camera angle, so the use of surround photography is becoming more and more widespread. [0004] In the prior art, there are many ways of shooting around the field. For example, if a single lens is used to cooperate with the rotation of the lens, the rotation method can be a general camera lens combined with hand movements to rota...

Problems solved by technology

[0005] There are also some surround-field photography methods that use a 360-degree ultra-wide-angle lens to shoot and record images above the viewing point. This method often makes the captured image greatly distorted, especially the depth of the image, so the viewer cannot actually produce a correct image. The sense of spatial depth does not conform to the habit of human beings to observe objects, and in most cases, it is difficult to place the lens above the viewing area
