Abstract

The invention discloses a dual-spectrum viewer synchronous view field control system based on a stepping motor. The system comprises an infrared imaging system, a visible light imaging system and a control circuit. The system is characterized in that the control circuit has the consistent correspondence of zoom value and focusing value according to the infrared imaging system and the visible light imaging system, a control circuit adjusts the field synchronization of the infrared imaging system and the visible light imaging system. The synchronization method disclosed by the invention comprises the following steps: 1) acquiring a high-definition image; 2) reading the zoom value and focusing value of the current imaging system; 3) acquiring the field angle of the current imaging system; 4) acquiring the zoom value of a to-be-adjusted imaging system; 5) acquiring the focusing value of the to-be-adjusted imaging system; and 6) performing field synchronization. According to the system and method which are disclosed by the invention, as long as the lens position of a spectrum is manually adjusted, the automatic synchronization of the other spectrum field can be automatically realized, and the operation is convenient, efficient, accurate and reliable. The working efficiency of the equipment can be effectively improved, and intelligent monitoring of the dual-spectrum viewer is realized.

Description

technical field [0001] The present invention relates to a system and method for synchronous control of the field of view of a dual-spectrum observer based on a stepping motor. More specifically, it relates to a method for synchronous adjustment based on the consistent correspondence between the zoom value and the focus value of the two imaging systems. A stepping motor-based dual-spectrum observer field of view synchronization control system and method. Background technique [0002] With the development of the surveillance industry, different spectral imaging shows their own advantages in different environments. During daytime observation, visible light imaging has the advantages of high pixels, full color, and strong resolution; during nighttime observation, infrared imaging has the characteristics of long detection distance, strong concealment, and can penetrate harsh environments such as smoke, rain and snow. A single spectral imaging monitoring system can no longer meet...
