Abstract

The invention provides an automatic zooming method and device of electronic camera equipment, equipment and a storage medium. The method comprises the following steps: acquiring a current object distance, wherein the current object distance is an actual distance between a central point of a lens of the electronic camera equipment and a monitoring target actually scanned in an imaging view field ofthe camera; calculating an observation multiplying power according to the current object distance and preset observation precision; and if the observation multiplying power is not equal to the current multiplying power, adjusting the multiplying power of the electronic camera equipment to be the observation multiplying power. Therefore, in the whole process, a user does not need to perform zooming manually, zooming is automatically performed by the electronic camera equipment, and the requirements of intelligence and real-time performance are met.

Description

technical field [0001] The disclosure belongs to the technical field of video monitoring, and in particular relates to an automatic zooming method, device, equipment and storage medium of electronic camera equipment. Background technique [0002] With the development of the video surveillance industry, people have higher and higher requirements for the intelligence and real-time performance of surveillance equipment. When the electronic camera equipment is shooting a dynamic target, if the focal length of the electronic camera equipment is fixed, the size of the target on the screen will also change with the distance from the target. If a certain observation accuracy is to be maintained, the electronic camera The equipment zooms to keep the imaging size of the shooting target within a suitable size range. [0003] At present, most cameras need to be zoomed manually, which cannot meet the needs of intelligence and real-time performance. Therefore, a new method is urgently ne...
