Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as figure 1 As shown, the circuit principle diagram of the dual-field thermal imager intelligent control system of the present invention is given, which includes a microprocessor 2, an infrared lens 11, a thermal imaging detector 10, a limit switch 1, a stepping motor 5. Motor drive circuit 6, photoelectric encoder 8, EEPROM memory 3, temperature sensor 9; the microcontroller has the functions of collection, calculation and control. The infrared rays emitted by external objects enter through the infrared lens 11, and the thermal imaging detector 10 is used to transmit light signals Converted into electrical signal, can form video signal and output. The limit switch 1 is used to detect whether the infrared lens 11 is in the initial position. For example, when the infrared lens 11 is in the initial position, the limit switch 1 is low, and the microcontroller ...

Abstract

The invention discloses an intelligent control system of a double-field of view thermal imager. The intelligent control system comprises an infrared lens, a thermal imaging detector, a microprocessor, a stepping motor and a limit switch. The intelligent control system is characterized in that the microprocessor drives the stepping motor to operate through a motor driving circuit, and the input end of the microprocessor is connected with a photoelectric encoder and a temperature sensor. A control method of the intelligent control system of the double-field of view thermal imager comprises the steps of (a) detecting states, (b) moving to a starting position, (c) determining the distance of a large field of view, (d) moving to the position of the large field of view, (e) judging whether switching of fields of view is needed, (f) determining the position and temperature, (g) acquiring a reference temperature, (h) judging whether position compensation is needed, (i) switching to a small field of view, (j) determining focus bias quantity, (k) conducting forward compensation, and (l) conducting reverse compensation. The double-field of view thermal imager can be used for focus position compensation of the fields of view at different temperatures, is accurate, reliable, stable in operation, capable of meeting quick switching between the fields of view, and capable of being widely applied to many fields including weaponry, scout monitoring, people search and rescue and the like.

Description

Technical field [0001] The invention relates to an intelligent control system and method for a dual-field thermal imager, and more specifically, to a dual-field thermal imager that can quickly and accurately switch the field of view and perform intelligent compensation of the focus position according to changes in ambient temperature Intelligent control system and method of dual-field thermal imager. Background technique [0002] Infrared light cannot be perceived by human eyes because of its long wavelength, and it is invisible light. As part of the electromagnetic spectrum, we can detect its heat. As long as the temperature of the object is above absolute zero, it will radiate heat outward. Thermal imaging technology is a technology that "sees" or "measures" the heat radiated by an object by using an infrared imaging measuring instrument. The infrared optical lens on the thermal imaging detector focuses the infrared rays emitted from the object. The detector sends informati...
