Image acquisition method and device

Abstract

The invention relates to an image acquisition method and an image acquisition device. The method comprises the following steps: identifying a target from images acquired by image acquisition equipment, determining the image acquisition equipment which acquires the target according to the result of target identification, and taking the image acquisition equipment as the current image acquisition equipment; closing all the image acquisition equipment other than the current image acquisition equipment; determining the position of the target in an image and the direction of movement of the target; comparing the position with a preset threshold, and determining an image area where the target is located; opening the image acquisition equipment in a corresponding direction of the current image acquisition equipment according to the orientation of a first or third area relative to the image if the target is in the first or third area; and opening the image acquisition equipment in a corresponding direction of the current image acquisition equipment according to the direction of movement of the target and closing the current image acquisition equipment if the target is in a second area. By adopting the method and the device, the consumption of power capacity of a detection system is reduced effectively, and image data for processing and stitching is reduced.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to an image acquisition method and an image acquisition device. Background technique [0002] All kinds of natural disasters and incidents endangering public safety occur from time to time in China, such as earthquakes, ice disasters, floods, fires, etc. Timely handling of natural disasters, including rescue of the wounded, search of missing persons, prevention of secondary disasters, etc., especially in special environments, inconvenient traffic, and communication interruption conditions, to outperform the "golden 72 hours", the detection system The time and speed of deployment is particularly important. [0003] Video image surveillance system is widely used in the field of public security, military detection and private detection and so on. With the development of technology, the theory, technology and method of automatic identification and tracking are currently a re...
