Infrared thermal imaging instrument and method capable of implementing presetting function based on stepping motor

Abstract

The invention discloses an infrared thermal imaging instrument capable of implementing a presetting function based on a stepping motor. The infrared thermal imaging instrument comprises an imaging zooming lens group, an imaging focusing lens group, a thermal imaging detector assembly and a control circuit board, and is characterized in that the control circuit board respectively drives the imaging zooming lens group and the imaging focusing lens group to work through a zooming stepping motor assembly and a focusing stepping motor assembly. A method comprises the following steps of: mounting the thermal imaging instrument; initializing the thermal imaging instrument; manually zooming and focusing; reading zooming and focusing information; and storing the information. A preset position calling method comprises the steps of judging a scene to be monitored, calling the information, adjusting the thermal imaging instrument, and acquiring a clear image. By the infrared thermal imaging instrument and method, the clear image is acquired at first time, and the zooming and focusing information at the moment is stored; during cruise monitoring, the clear image in the specific scene can be acquired by calling the zooming and focusing information stored before; and manual adjustment is not needed, and thus the efficiency is higher.

Description

technical field

[0001] The present invention relates to an infrared thermal imager and a method based on a stepping motor to realize a preset position function, more specifically, to a zoom infrared thermal imager that first manually sets and stores zoom and focus information and then recalls it and methods. Background technique

[0002] With the development of infrared thermal imaging technology, a continuous zoom infrared thermal imager (patent application number 200810015710.6) has appeared. The operator can independently control the zoom and focus of the thermal imager at the background control terminal. Using the same lens, both Large-scale search can also be used to zoom in and identify targets, which is convenient for monitoring. Since the thermal imager is mostly used outdoors and is for cruise monitoring of a wide range of targets, during the cruise monitoring process, it is often necessary to perform imaging for different scenes and different targets.
