Embodiment Construction

[0056]In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only Some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Any object with a temperature higher than absolute zero is constantly emitting infrared radiation, and the wavelength of the external radiation is different at different temperatures. An infrared thermometer is a device that receives the thermal radiation of the measured target, converts it into an electrical signal, and finally outputs temperature inform...

Abstract

The invention discloses a signal processing method, device and electronic equipment for infrared temperature measurement, belonging to the technical field of temperature measurement. The methods include: obtaining the radiation characteristic value corresponding to the measured target; obtaining the main analog signal obtained by detecting the infrared radiation of the measured target in the imaging band range by the infrared detection device, and obtaining the infrared radiation obtained by detecting its infrared radiation in the low attenuation band range The reference analog signal; the main analog signal is converted into the main digital signal, and the reference analog signal is converted into the reference digital signal; the target digital signal is obtained by calculating according to the radiation characteristic value, the reference digital signal and the main digital signal. The invention uses the radiation energy of the measured target in the low-attenuation band and the measured low-attenuation analog signal in the low-attenuation band to correct the actually measured digital signal, and compensates the error caused by the atmospheric attenuation correction caused by the different measured target materials.

Description

technical field [0001] The invention relates to the technical field of temperature measurement, in particular to a signal processing method, device and electronic equipment for infrared temperature measurement. Background technique [0002] Infrared thermal imaging camera is a kind of infrared radiation energy that uses infrared detector and optical imaging objective lens to receive the infrared radiation energy of the measured target, and reflects the energy distribution pattern on the photosensitive element of the infrared detector, and obtains the infrared radiation that can directly reflect the heat degree of the measured target. Instrumentation for thermal images. Its main working principle is to convert the infrared radiation of the measured target into an electrical signal after capturing the infrared radiation, and output the temperature signal through algorithm processing. During the process of the infrared thermal imaging camera receiving the infrared radiation of...
