After the reflected sunlight directly enters the thermal imaging lens, it will cause a pseudo-high temperature area (also called a reflection point) in the thermal imaging image formed by the thermal imaging lens. The imaging grayscale value of the reflection point is much higher than that of the reflection The grayscale value of the image corresponding to the actual temperature of the object represented by the point, which seriously affects the accuracy of temperature measurement and high temperature alarm

Embodiment Construction
[0098] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art based on this application belong to the scope of protection of this application.
[0099] For ease of understanding, the words appearing in the embodiments of the present application are explained below.
[0100] Pixel: It is composed of small squares of the image. These small squares have a clear position and assigned color value. The color and position of the small squares determine the appearance of the image.
[0101] The area occupied by the pixel: the small square representing the pixel at the position of the pixel in the image is the area occupied by the pixel. ...

The embodiment of the invention provides a data processing method and device, and the method comprises the steps: carrying out the detection of a thermal imaging image, and obtaining a high-temperature target; determining an imaging area of a high-temperature target in the thermal imaging image in the visible light image; determining an overexposure area in the imaging area; if the proportion of the overexposure area in the imaging area is larger than a preset proportion threshold value, processing operation corresponding to the reflection point is executed on the high-temperature target. Therefore, temperature measurement errors and high-temperature false alarms caused by the fact that the reflective points are mistakenly considered as heat source points can be effectively avoided, and the accuracy of temperature measurement and high-temperature alarm is further improved.
Description
technical field [0001] The present application relates to the technical field of infrared thermal imaging, in particular to a data processing method and device. Background technique [0002] The infrared radiation energy of the sun is extremely strong, and the sunlight still has extremely high energy after being reflected by objects with smooth surfaces and high reflectivity. After the reflected sunlight directly enters the thermal imaging lens, it will cause a pseudo-high temperature area (also called a reflection point) in the thermal imaging image formed by the thermal imaging lens. The imaging grayscale value of the reflection point is much higher than that of the reflection The grayscale value of the image corresponding to the actual temperature of the object represented by the point seriously affects the accuracy of temperature measurement and high temperature alarm. Contents of the invention [0003] The purpose of the embodiment of the present application is to pr...
