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...
