Embodiment 1

[0063] This embodiment provides a method for identifying the color of a vehicle annual inspection label, which can be used in a device for identifying the color of a vehicle annual inspection label. Such as figure 1 As shown, the method includes the following steps:

[0064] In step S11, the first color space of each pixel in the image of the annual inspection label to be recognized is obtained, and the first color space includes hue.

[0065] After acquiring the image of the annual inspection label to be identified, the device for identifying the color of the annual inspection label of the vehicle extracts the first color space of each pixel in the image. Wherein, the first color space includes hue.

[0066] Step S12, confirming the color of each pixel in sequence according to the hue.

[0067] The identification device for the color of the vehicle annual inspection label confirms the color of each pixel according to the hue of each pixel in the first color space.

Embodiment 2

[0086] This embodiment provides a method for identifying the color of a vehicle annual inspection label, which can be used in a device for identifying the color of a vehicle annual inspection label. Such as figure 2 As shown, the method includes the following steps:

[0087] Step S21, acquiring the first color space of each pixel in the image of the annual inspection label to be recognized, where the first color space includes hue.

[0088] It is the same as step S11 in Embodiment 1, and will not be repeated here.

[0089] Step S22, confirming the color of each pixel in sequence according to the hue.

[0090] Wherein, the first color space also includes saturation and brightness. By removing the saturation of each pixel not in the first preset range and the brightness not in the second preset range, that is, by discharging pixels that obviously do not have color (for example, pure white or pure black), It can improve the efficiency of annual inspection label color recogni...

Embodiment 3

[0110] This embodiment provides a method for identifying the color of a vehicle annual inspection label, which can be used in a device for identifying the color of a vehicle annual inspection label. Such as image 3 As shown, the method includes the following steps:

[0111] Step S31, acquiring the first color space of each pixel in the image of the annual inspection label to be recognized, where the first color space includes hue.

[0112] Specifically, the following steps are included:

[0113] Step S311, acquiring the second color space of each pixel in the image of the annual inspection label to be recognized.

[0114] After acquiring the image of the annual inspection label to be identified, the device for identifying the color of the annual inspection label of the vehicle extracts the second color space of each pixel in the image. For example, each pixel corresponds to the RGB color space as (R m , G m , B m ).

[0115] Step S312, performing normalization processi...

Abstract

The invention discloses a method and device for identifying the color of a vehicle annual inspection label, wherein the method includes: acquiring the first color space of each pixel in the image of the annual inspection label to be identified, the first color space includes hue; The color of each pixel; count the number of pixels corresponding to each color; judge whether the number of pixels corresponding to each color meets the preset condition; when it is satisfied, use the color with the largest number of corresponding pixels as the color to be identified The color of the annual inspection label image; when it is not satisfied, cut the image of the annual inspection label to be recognized, and use the cut image of the annual inspection label to be recognized as the image of the next cycle, and return to execute to obtain each pixel in the image of the annual inspection label to be recognized The steps of the first color space. When the quantity does not meet the preset conditions, the image of the annual inspection label to be recognized is cut and the color recognition is performed again, so as to eliminate the influence of some factors due to illumination and folding.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for identifying the color of a vehicle annual inspection label. Background technique [0002] With the rapid development of the economy, the number of urban motor vehicles has increased rapidly, the contradiction between the current situation of traffic management and the demand has further intensified, and the criminal and public security cases related to vehicles have also increased year by year. Especially the theft of motor vehicles, motor vehicle hit-and-run and vehicle-related criminal cases have seriously affected social security and the interests of the people. [0003] Therefore, in order to solve the problem of urban development and realize the sustainable development of the city, the construction of "smart city" has become an irreversible historical trend of urban development in my country today; The Ministry of Industry and the Ministry of...
