Problems solved by technology

[0004] The present invention proposes a method and device for partial occlusion of video images. By automatically adjusting the size of the occlusion frame when the network camera moves, the occlusion frame can always just cover the privacy area, which solves the problem of overflow or occlusion of the actual privacy area in the prior art. The problem that the frame blocks the monitoring screen

Embodiment Construction

[0041] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0042] Such as figure 1 As shown, the technical solution is a method for partial occlusion of a video image, which is applied to a video surveillance camera and includes the following steps:

[0043] Detect the position change and calculate the displacement caused by the position change;

[0044] According to the displacement, the preset blocking frame is adjusted so that the actual monitoring area covered by it remains unchanged.

[0045] The following is a detailed description through specific embodiments. In this embodiment, the video surveillance camera is an example of a network camera IPC (IP Camera), which is hereinafter referred to as a camera. It is also applicable to other cameras or encoders with intelligent processing m...

Abstract

The invention discloses a method for partial occlusion of a video image, which is applied to a video surveillance camera. The method for partial occlusion of a video image first detects a position change and calculates the displacement caused by the position change; then according to the displacement, the preset Adjust the occlusion frame to keep the actual monitoring area covered by it unchanged. The invention also discloses a device for partial occlusion of video images, which includes a detection module and an adjustment module. The method and device of the present invention automatically adjust the shielding frame, the adjustment process of the shielding frame is automatic for the user, and the shielding frame adaptively covers the privacy area, bringing good user experience.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and device for partial occlusion of a video image. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In video surveillance, in order to block privacy areas or other areas that cannot be monitored, a block frame is usually set on the video image for block. [0003] When the current network camera IPC blocks the privacy area, usually the user manually sets a block frame in the video image, and the live screen sets the block frame to black or white or mosaic to achieve the blocking effect. However, for the IP camera IPC with a pan / tilt, when the pan / tilt moves, although the actual covered area does not change, when the size of the occlusion frame in the video image frame does not ch...
