Multi-lens optical center superposing type omnibearing shooting device and panoramic shooting and retransmitting method

Abstract

The invention relates to a multi-lens optical center superposing type omnibearing shooting device and a panoramic shooting and retransmitting method. A special optical path design is adopted to superpose the optical centers (comprising practical optical centers and virtual optical centers) of video cameras in different directions and eliminate the defects caused by optical path cross; meanwhile, images in global, semiglobular or circular regions are collected so that the information of video images in different depths of field can be well connected to form an integral omnibearing image. A user playing the video images at a client can select a needed view by moving a mouse, a rocker or a remote control, i.e., uplink data to be sent to a video server is changed. The video server cuts the generated panoramic video into different contents and sends the contents to corresponding clients according the requirements of the clients so that different users can freely view interested regions without mutual influence, the function for spectators at the clients to personally select fields of view is realized, and the spectators can glance to the left and to the right to have an immersed sense.

Description

Technical field [0001] The invention relates to a set of camera and broadcasting devices and methods, in particular to a group of multi-lens optical center coincident omni-directional camera devices and methods for panoramic shooting and broadcasting, belonging to the field of video surveillance and video broadcasting. Background technique [0002] Now let’s explain the camera monitoring equipment used in the field of security protection: After investigation and consulting information, the camera part of the commonly used security monitoring system at present, such as: German Bosch VG4300 series high-speed dome camera, American Nuctech VC-881 high-speed dome camera Cameras and YUCOO-NC7201 network cameras of Guangzhou Youke Video Equipment Co., Ltd. and other monitoring devices can not only be used for regional monitoring based on computer local area networks, such as traditional monitoring of residential quarters, office buildings, banks, shopping malls, etc.; In cross-regi...

AI Technical Summary

Problems solved by technology

However, the compound-eye omni-directional camera device also has certain defects: First, when multiple cameras are combined into a compound-eye omni-directional camera device, there will be video blind spots due to the intersection of optical paths. , resulting in a large workload

Second, the method of video transmission also has defects: all-round video information (360 degrees by splicing 4-8 images or 180 degrees by splicing 2-4 images)

However, the completion of the above functions requires high video compression, transmission rate and network bandwidth.

Therefore, due to the defects in the process of realizing panoramic camera and broadcasting of the utility model patent (Patent No.: ZL00245946.9) of the compound-eye omnidirectional camera device applied by the applicant on July 28, 2000, many occasions such as low network bandwidth difficult to achieve
