Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0026] In the embodiment of the present invention, the security monitoring system is at least composed of a security monitoring device and at least one camera. Wherein, the monitoring device is located in the monitoring center, and the monitoring device can receive the video stream collected by each camera (composed of pictures collected in continuous time), and display the video stream received from each camera, and the display method includes at least : 1. Display the video st...

Abstract

The invention provides a camera based image generating method and device, suitable for the security monitoring field. The method comprises that a display proportion sent from a monitor is received; all pick-up heads in the camera carry out shooting, and pictures shot by the pick-up heads are stored in a memory; according to the joint sequence of the pick-up heads, the pictures shot by the pick-up heads are joint into a panorama picture; two cutting lines which cut the panorama picture in the display proportion are determined; and pictures between the two cutting lines are read from the memory, and then sent to the monitor. Thus, the monitor of a security monitoring center displays the received picture, namely the panorama picture between the two cutting lines, in the display proportion, black edges do not exist, and abnormal phenomena as picture distortion or deformation do not occur.

Description

technical field [0001] The invention belongs to the field of security monitoring, in particular to a camera-based image generation method and device. Background technique [0002] In the existing security monitoring system, the monitoring device in the monitoring center uses an aspect ratio of 16:9 to display the video stream received from each remote camera. [0003] However, the pictures contained in the video stream output by the existing security cameras do not all meet the 16:9 ratio. If the monitoring device in the monitoring center directly uses the aspect ratio of the received pictures to display, black borders will appear on the top and bottom of the screen. Affect the browsing effect; if the monitoring device in the monitoring center adopts an aspect ratio of 16:9, the image will be distorted. Contents of the invention [0004] The purpose of the present invention is to provide a camera-based image generation method and device to solve the problem that the displ...
