Embodiment Construction

[0081] The embodiment of the present application discloses a monitoring method based on an omnidirectional camera.

[0082] refer to figure 1 and figure 2 , a monitoring method based on an omnidirectional camera, comprising steps S1000~S5000:

[0083] Step S1000: Capture video image information obtained by all cameras in the camera group.

[0084] Step S2000: Store all video image information in the shared buffer area respectively.

[0085] Wherein, the video image information is stored in the shared buffer area in the form of its pixel matrix, each pixel includes the brightness and color information of the pixel, and each video processor facing the video client can access the shared buffer area.

[0086] Step S3000: Receive instruction information sent by the video client.

[0087] The video processor receives instruction information from the video client, and the instruction information includes virtual range information, shielded range information, and output resolutio...

Abstract

The invention relates to the technical field of computers, in particular to a monitoring method and system based on an omnidirectional camera. The method comprises the following steps: capturing video image information acquired by all cameras in a camera group; respectively storing all video image information in a shared cache region; receiving instruction information sent by the video client; extracting video image information from the shared cache region based on the instruction information and processing the video image information to obtain target video image information; and sending the target video image information to the video client. And the video processor carries out operations such as cutting, synthesis and digital zooming on the video image information acquired by the camera group according to the watching requirement of each video client, simulates a virtual camera, and outputs target video image information in any orientation and zooming proportion required by the video client.

Description

technical field [0001] The present application relates to the technical field of video communication, in particular to a monitoring method and system based on an omnidirectional camera. Background technique [0002] A camera (CAMERA or WEBCAM) is a video input device, a type of closed-circuit television, and is widely used in video conferencing, telemedicine and real-time monitoring. [0003] In the related technology, the camera generally has basic functions such as video photography, broadcasting and static image capture. The signal is then input to the computer through the parallel port and USB connection, and then the software restores the image to form a picture. [0004] With regard to the above related technologies, the inventor believes that it is difficult for the cameras in the related technologies to control the camera to quickly turn to the target of interest according to the requirements of the video client. Contents of the invention [0005] In order to out...
