Camera assembly and monitoring camera

Abstract

The present application provides a camera assembly, which comprises a panoramic camera, a PTZ camera, and a processor. The panoramic camera is used to collect wide-angle images of a monitoring scene; the PTZ camera is used to collect narrow-angle images in different directions of the monitoring scene; the processor is configured to superimpose, in response to an instruction input from outside, a polygon frame corresponding to the instruction on the wide-angle image; select, according to a preset mapping table of wide-angle image coordinates and narrow-angle image coordinates, at least two ordinate values on the polygon frame in the wide-angle image, to obtain at least two ordinate values on the narrow-angle image, thereby determining an effective focus value interval of the PTZ camera, so that the PTZ camera performs a focusing operation within the effective focus value interval during a focusing process.
