Method for measuring the visual factor of an energy body to an object

The invention relates to a method for measuring the visual factor of an energy body to an object, in particular to a visual factor environmental parameter of a geometric relationship of energy projection, and a method for measuring a visual factor of a stereoscopic space temperature measurement more accurately.

In recent years, with the development of infrared thermal imaging devices, infrared thermal imaging devices provide non-contact, non-invasive, non-destructive and non-harmful radiation measurement methods, and the corrected infrared thermal imaging device Accuracy can reach plus or minus 2%.

However, the current measurement temperature method is inaccurate in some cases, because the environmental parameters are not taken into consideration, such as: the emissivity of the analyte, the measurement distance, the humidity in the space, and the mutual interaction between the objects. Influence and so on. In order to solve the above problems, the practice is mostly to use manual input of environmental parameters for correction, but does not consider the factors caused by environmental geometry.

For example, an infrared thermometer laser adjustment structure disclosed in the Patent No. I486565 of the Republic of China, "Laser Adjustment Device for Radiation Thermometer, Laser Adjustment System and Laser Adjustment Method", enables the laser adjustment device to be quickly and accurately adjusted to The correct location. It uses the heat radiation device to sense the temperature information, and uses the laser device at the center of the device to perform distance sensing of a single pixel, and then combines the temperature with the distance to obtain the correct temperature value of a single pixel. However, the above method Although the temperature information of a single pixel can be obtained, the thermal radiation relationship between any two pixels in the entire stereoscopic space cannot be calculated.

Another method disclosed in the "Highly Adaptive Thermal Characteristic Measurement System and Method" of the Patent No. I485396 of the Republic of China Patent No. I485396 can quickly measure the situation without actually lighting or applying any power to a component to be tested. A method of measuring various thermal property values of an element. It uses a thermal property measurement system to obtain the temperature distribution of the component under test and generate a thermal image. However, the above method provides a measure of the quality of the component to be tested rather than an accurate temperature measurement, and although it reveals a measurement method at a fixed distance, it cannot automatically adapt to different distances for measurement.
