Problems solved by technology

[0003] However, in most cases, the target object is a moving object and will not always remain within the field of view of a camera. If the images collected by all cameras in an area are transmitted and recognized, the work of image processing will inevitably be increased It will also cause the tension of transmission bandwidth and waste of power consumption

Abstract

Embodiments of the present invention provide an image acquisition method and its device, and an image transmission method and its device. The image acquisition method includes: receiving a first image containing a tracking target object; acquiring a second image; performing image recognition on the second image based on the first image and the second image; when the second image contains the tracking target object , send the second image. Through the solution provided by the above embodiments of the present invention, multiple monitoring devices can be implemented to work together to track suspicious targets. The invention effectively utilizes network bandwidth, reduces network bandwidth pressure, and avoids waste of power consumption of network equipment.

Description

technical field [0001] The invention relates to an image acquisition method and its device applied to electronic equipment, and an image transmission method and its device applied to a server. Background technique [0002] At present, the network monitoring system has been widely used. For example, one or more monitoring devices such as cameras are installed at important traffic intersections or public places to monitor the surrounding environment in real time. When necessary, the collected images will be analyzed and identified to deal with abnormal situations in a timely manner. [0003] However, in most cases, the target object is a moving object and will not always remain within the field of view of a camera. If the images collected by all cameras in an area are transmitted and recognized, the work of image processing will inevitably be increased It will also cause tension in transmission bandwidth and waste of power consumption. So how to efficiently use the limited b...
