A temperature measurement method based on camera module

Abstract

The method belongs to the temperature measurement technical field and provides a camera module set-based temperature measurement method. The method includes the following steps that: a temperature measurement instruction inputted by a user is obtained; an RAW mode.ini program of a camera module set of terminal equipment is called to assign the camera module set; the camera module set images content corresponding to a reference area onto an image sensor of the camera module set; a temperature-induced light transmission variable material layer adjusts light sensing quantity of the image sensor, and the image sensor processes the content of imaging according to the light sensing quantity, so that a picture which contains brightness degree information and is matched with current temperature can be obtained; and the temperature of an environment where the terminal equipment is located can be calculated according to the brightness degree information of the picture and a corresponding relationship between pre-formed temperature and the brightness degree information of the picture, and the temperature of the environment where the terminal equipment is located is displayed. Thus, with the method adopted, the temperature of the environment where the terminal equipment is located can be measured fast and conveniently under the premise that the quality of the output picture is not affected.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement, in particular to a temperature measurement method based on a camera module. Background technique [0002] Temperature testing has been widely used in many fields such as household, industrial manufacturing, navigation, aerospace, etc. The commonly used temperature testing methods mainly include the following methods: [0003] (1) Contact measurement, such as the common use of the principle of thermal expansion and contraction of thermometers, under the condition of constant external pressure, when the temperature rises, its volume increases, and when the temperature decreases, its volume shrinks, so as to realize temperature measurement; [0004] (2) Thermistor or thermocouple measurement, using the principle that the electrical parameters of the material will change when the temperature is different, to achieve temperature measurement; [0005] (3) Infrared temperature measureme...
