Abstract

The invention belongs to the field of camera shooting, particularly relates to a high-speed virtual camera system based on a galvanometer, an observation method and equipment, and aims to solve the problem that a plurality of objects cannot be remotely observed in real time at high definition in the prior art. The system comprises a computer used for obtaining a to-be-observed position on a set observation plane; a DA signal converter, used for converting the received digital signal into an analog signal; a galvanometer control panel, used for analyzing the received analog signal into a control instruction; a galvanometer unit, used for controlling a lens of the scanning electron microscope to rotate according to the control instruction, acquiring an optical signal of a to-be-observed position and reflecting the optical signal; and a high-speed camera, used for shooting the optical signal reflected by the scanning electron microscope, acquiring a high-definition image of a to-be-observed position on the set observation plane and sending the high-definition image to the computer. According to the invention, remote real-time and high-definition shooting of multiple targets can be realized.

Description

technical field

[0001] The invention belongs to the field of imaging, and in particular relates to a vibrating mirror-based high-speed virtual camera system, observation method and device. Background technique

[0002] In the process of shooting long-distance objects, due to the limitation of the focal length of ordinary cameras, short-focus cameras can obtain a larger field of view, usually with a viewing angle of more than 60 degrees, but cannot describe detailed information, and it is blurry when shooting long-distance images; telephoto cameras It is clearer and retains more details when shooting distant objects, but the field of view is narrow, usually within 15 degrees, and only small-scale scene observation can be performed.

[0003] In order to shoot a large range of long-distance objects with high definition, two methods are mainly used at present. One is to arrange a large number of telephoto cameras in an orderly manner to form a camera array. In the later stage, ...
