Matters needing attention in taking images with thermal imager

The working principle of infrared thermal imager is to shoot images at different temperatures according to its infrared imaging principle, and then find out the exact position of the required object smoothly according to the images. As long as the object itself has a temperature, researchers can use this device to shoot its infrared imaging. When using this equipment, we have a lot to pay attention to. We should also be more careful when shooting infrared images. Usually use this equipment should pay attention to three aspects. We must master the parameters and accuracy of these three aspects in order to shoot accurate infrared images. Let's talk to you about three aspects that need our attention.

1, determine the temperature range.

The infrared thermal imager can measure the temperature by itself, and it can intelligently generate infrared images according to the surrounding temperature. However, this kind of equipment must set a certain temperature range before use, and it can work more accurately in a certain temperature range. Therefore, before using the equipment, researchers should first select the temperature range, and set the equipment to automatically adjust the temperature range and manually adjust the temperature range. In other words, we have to set the temperature range artificially at work, and then the equipment will measure the temperature itself. This working principle is beneficial to improve the working efficiency of thermal imager and reduce the temperature measuring time.

2. Adjust the focal length

Since it is used to take pictures, the infrared thermal imager has some camera functions, and the focal length should be adjusted during use. Too high or too low focal length range is not conducive to reading temperature. At present, most thermal cameras on the market have auto-focusing function, which can be focused manually, and users can use it according to their own needs.

3, shooting to avoid the influence of the environment.

When using infrared thermal imager to shoot outdoors, it will inevitably be affected by the environment. In particular, direct sunlight will have a great impact on shooting. The temperature of the environment and the temperature of the sun increase the temperature of unmarked objects, so it is difficult for the equipment to take correct imaging pictures. On the contrary, if the ambient temperature is too low, it will still affect the shooting, and the object will blend in with the surrounding environment, making it more difficult for us to judge the exact position of the object. When using this equipment, we try to avoid such weather.

At present, many infrared thermal cameras also have the function of taking visible light photos. For example, RNO IR 160 upgraded infrared thermal imager, equipped with 1.3 million pixel visible light camera, can be associated with infrared pictures to store visible light pictures, which have infrared original measurement data. It is suitable for detecting the same or similar indistinguishable targets. The accompanying image may be accompanied by a 60-second voice annotation. With Micro SD memory card, it comes with 8GB as standard and can be expanded to 16GB at the highest.

IR 160 upgraded thermal imager adopts uncooled focal plane micro-thermal detector, 160x 120 pixels. Uncooled infrared detector does not need to install refrigeration device in the system, so it is small in size, light in weight and low in power consumption. In addition, compared with refrigerated photon detectors, they can provide wider spectral response and longer working time. Therefore, uncooled technology can provide users with high-sensitivity sensors with lower cost and higher reliability.

In addition, the IR 160 upgraded thermal imager is equipped with a frame rate of 50/60Hz. Frame rate refers to the number of frames or images displayed or displayed per second. The higher the frame rate, the faster the animation speed, and the lower the frame rate will lead to intermittent playback. The temperature range of traditional thermal imager within 40,000 yuan is generally within -20℃~+250℃, while the temperature range of IR 160 upgraded thermal imager can reach -20℃~+650℃. A wider temperature measurement range can ensure more application fields. When the target temperature exceeds the set temperature, an alarm will be triggered, and all areas above the set temperature will display the alarm color. If no alarm color is set, there is only alarm sound.

The upgraded version of IR 160 thermal imager has a variety of temperature measurement modes, which are suitable for various targets and requirements. It can detect four movable points, three movable areas (the highest temperature, lowest temperature and average temperature are automatically captured in the areas), two temperature measuring lines, isothermal analysis, temperature difference measurement and temperature alarm (sound and light) in real time. The error range of temperature measurement is 2℃ or 2% of reading.
