Problems solved by technology

[0005] However, deploying multiple cameras and using the central control system to calculate and analyze the situation of each camera for tracking and monitoring is prone to errors; and although the PTZ camera with an intelligent system can track the target object, it is powerless to monitor multiple target objects, and when the target Real-time tracking is difficult when objects move irregularly or too fast

Embodiment Construction

[0034] The present invention will be described in further 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.

[0035] Embodiments of the present invention describe an image processing method, such as figure 1 shown, including the following steps:

[0036] In step 101, a composite operation is performed based on at least two frame image streams to obtain a panoramic frame image stream corresponding to the environment.

[0037] There are at least two image acquisition devices (such as cameras) in the environment, and each image acquisition device collects the environment in a specific acquisition direction and outputs a frame image stream. Since it is necessary to obtain a 360-degree panoramic frame image stream corresponding to the environment, Therefore, the acquisition directions of the image acquis...

Abstract

The invention discloses a method and device for processing an image. The method comprises the steps of conducting synthetic operation based on two or more branches of frame image flows, and obtaining a panorama frame image flow which corresponds to the environment; analyzing first operation specific to the panorama frame image flow, and obtaining a target area indicated by the first operation in the panorama frame image flow; selecting a target object from objects carried by the target area of the panorama frame image flow, and detecting the position of the target object in each panorama frame image of the panorama frame image flow; based on the position of the target object in each panorama frame image of the panorama frame image flow, segmenting the target object from each panorama frame image, and generating a panorama frame image flow corresponding to the target object. By means of the method and device, multiple target objects can be monitored and tracked accurately.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image processing method and device. Background technique [0002] With the rapid development of video surveillance system technology, video surveillance has become an important technical means for state organs, enterprises and institutions, as well as residential security protection and family entertainment communication. Traditional video surveillance mainly relies on manual monitoring and manual switching of monitoring perspectives. With the improvement of computer performance and the development of image processing technology, intelligent video surveillance shows outstanding advantages such as strong alarm initiative, long-term work, and low labor cost, and has gradually become a development trend. [0003] Due to the limitation of the camera angle, often one camera can only monitor one direction. If you want to monitor the situation in all directions, you need to dep...
