Document Type and Number:
WIPO Patent Application WO/2020/147792
Kind Code:
A1
Abstract:
The embodiments of the present application provide a video display method, device and system, and a video camera. The video camera comprises: a large-field-of-view lens assembly and a large-field-of-view sensor corresponding to the large-field-of-view lens assembly; and at least one small-field-of-view lens assembly and a small-field-of-view sensor corresponding to the small-field-of-view lens assembly, the field-of-view angle of the large-field-of-view lens assembly being greater than the field-of-view angle of the small-field-of-view lens assembly, and for the same target, the definition of the large-field-of-view sensor being less than the definition of the small-field-of-view sensor; and a processor, for performing human body analysis on a large-field-of-view image, and performing human face analysis or head and shoulder analysis or human body analysis on at least one frame of small-field-of-view image. The technical solutions provided in the embodiments of the present application can reduce the workload of installing and debugging a video camera for monitoring, lower performance requirements on a server, and reduce monitoring costs.
