Embodiment 1

[0026] A temperature detection method provided by an embodiment of the present invention is introduced in detail.

[0027] refer to figure 1 , shows a flowchart of steps of a temperature detection method in an embodiment of the present invention.

[0028] Step 101, acquiring a target picture taken on the target surface; the target surface is coated with thermochromic liquid crystal.

[0029] Liquid crystal is a substance between liquid and solid matter. It not only has the fluidity and surface tension of liquid, but also has the characteristics of optical anisotropy and birefringence of solid crystal. Thermochromic liquid crystals change color due to temperature changes, so they are also called display liquid crystals or color-changing liquid crystals. Thermochromic liquid crystals change color due to temperature changes, have millisecond-level time response and temperature response, and a temperature resolution of 0.10°. Therefore, in the embodiment of the present invention...

Embodiment 2

[0040] A temperature detection method provided by an embodiment of the present invention is introduced in detail.

[0041] refer to figure 2 , shows a flowchart of steps of a temperature detection method in an embodiment of the present invention.

[0042] Step 201, acquiring a target picture taken on the target surface; the target surface is coated with thermochromic liquid crystal.

[0043] Step 202, performing color analysis on the target picture to obtain the color distribution of the target picture.

[0044] In the embodiment of the present invention, color analysis may be performed on the target picture to obtain the color distribution of the target picture. For example, the color of each pixel in the target picture can be confirmed in units of pixels, and then the color distribution of the target picture can be obtained; the target pattern can also be divided into multiple area units, and then color analysis is performed on each area unit to obtain The color distribu...

Embodiment 3

[0052] A temperature detection method provided by an embodiment of the present invention is introduced in detail.

[0053] refer to image 3 , shows a flowchart of steps of a temperature detection method in an embodiment of the present invention.

[0054] Step 301, acquiring a target picture taken on the target surface; the target surface is coated with thermochromic liquid crystal.

[0055] Step 302: Carry out color analysis on the preset target pixel in the target image, and compare the analysis result with the standard color temperature change curve corresponding to the thermochromic liquid crystal to obtain the temperature of the preset target pixel Curve.

[0056] In the embodiment of the present invention, it is also possible to pre-set preset target pixel points that need to perform color analysis on the target picture, wherein the preset target pixel point can be a single pixel point or multiple pixel points, or multiple preset target pixel points can also be set ta...

Abstract

The invention provides a temperature detection method and device, and relates to the field of temperature detection. The method comprises the steps that a target image photographed for a target surface is acquired; the target surface is coated by thermochromic liquid crystal; and color analysis is performed on the target image, and the analyze result is compared with a standard color temperature change curve corresponding to the thermochromic liquid crystal so as to obtain the temperature statistical result of the target surface. The problems of insufficiency of convenience and high cost of equipment caused by manual operation of the existing temperature detection method can be solved. The beneficial effects that the temperature statistical result of the target surface can be statistically obtained according to the thermochromic liquid crystal of the target surface automatically without manual operation, and the price is obviously reduced relative to that of the existing temperature detection equipment can be obtained.

Description

technical field [0001] The invention relates to the technical field of temperature detection, in particular to a temperature detection method and a temperature detection device. Background technique [0002] With the advancement of technology, mobile communication equipment has become more and more developed, and mobile terminals such as mobile phones have become indispensable necessities in human life. Take the mobile phone as an example. From the birth of the mobile phone to the present, the mobile phone has undergone many changes. From the beginning, it can only make calls and send messages, to the mobile phone with the function of broadcasting music, and now to the smart phone that integrates Internet entertainment, video and audio functions. [0003] As the functions of mobile terminals become more and more powerful, their power consumption becomes higher and higher. Using the mobile terminal to play games, charge the mobile terminal, watch videos, etc. will easily cau...
