Online infrared thermal imager and infrared thermal image data processing method

Abstract

The present invention belongs to the infrared detection technology field, and provides an online infrared thermal imager and an infrared thermal image data processing method. The online infrared thermal imager comprises a lens, a detector, a processor and a client which are connected orderly, and a CMOS interface of the detector and a CCD video interface of the processor are connected. The lens is used to gather the infrared radiation of a target object to the detector, and the detector is used to acquire the infrared radiation and transform the infrared radiation into the infrared image data of a RAW format. The processor is used to receive the infrared image data, encode into the video data of a predetermined format and package the video data of the predetermined format into the infrared image data packets of a predetermined protocol standard, and the client is used to determine the temperature of the target object according to the gray values of the gray images and transform the gray images into the infrared thermal images of pseudo colors. The online infrared thermal imager of the present invention does not need to adopt a field programmable gate array for level transformation, and enables the device development difficulty to be reduced, the device stability to be improved and the circuit structure to be simplified.

Problems solved by technology

[0002] At present, field programmable gate arrays are mostly used in infrared cameras for level conversion and signal format conversion, resulting in complex circuit structures, high equipment failure rates, difficult development, and difficult to guarantee the continuity of research and development work.

Even without the accumulation of ARM / DSP technology, people use industrial control boards such as PC104 for digital signal processing, which consumes a lot of power and generates a lot of heat, which affects the stability and life of the equipment.

Especially for temperature testing in harsh environments such as fire scenes, the equipment is required to respond quickly and the data is accurate. However, the existing infrared thermal imaging cameras are usually based on temperature sensors and single-chip microcomputers, which are difficult to meet the corresponding requirements.

[0003] Moreover, in terms of grain temperature measurement, the temperature sensors are placed in the granary according to a certain distribution density, and there are inevitably temperature blind spots or leakage points

When measuring the temperature of liquids such as hot springs and wells, thermometers are often used, and samples are taken at a certain time interval. This method will have the problem of poor real-time performance.

In addition, infrared thermal imaging cameras mostly rely on foreign imports, and the equipment prices are high
