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

Embodiment Construction

[0054] Specific embodiments will be described in detail with reference to the accompanying drawings.

[0055] Figure 1 is the video The field of view formed by the image light path cross camera group (Schematic diagram of the optical path of the video image of the compound-eye omnidirectional camera device patent applied by the applicant in 2000);

[0056]In the figure, three cameras are taken as an example: 1a, 1b, and 1c constitute a part of the camera group, and are deployed with a point as the center of the circle, evenly placed on a circle with the same radius as the center of the circle, and each camera is responsible for shooting 360 degrees or 180 degrees An angle in the field of view in degrees (the angle depends on the angle of view of the camera lens). The video images collected by the camera group can be combined into a complete 360-degree or 180-degree on-site omnidirectional video image. 2a in the figure is the blind area A1 existing in the optical path of the ...

A special optical path design is adopted to superpThe 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, iose 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 usermages 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.
