specific Embodiment approach 1

[0021] Specific implementation mode one: as figure 1 Shown, a kind of car instrument program self-adaptive downloading system based on graphic comparison mode includes:

[0022] It is used to use image processing technology to extract the characteristic value of the instrument and input it into the instrument information input module of the computer;

[0023] A database forming module for associating and locking the characteristic values ​​input into the computer with corresponding instrument programs to form a database;

[0024] It is used to connect the meter to be copied with the computer, collect the image of the meter to be copied through the camera, and transmit the information to the information acquisition module of the meter to be copied in the computer;

[0025] The instrument model analysis module to be copied is used to analyze the model of the instrument to be copied, find and display the program associated with the instrument to be copied and locked in the datab...

specific Embodiment approach 2

[0027] Specific implementation mode two: the difference between this implementation mode and specific implementation mode one is: the image processing technology is specifically:

[0028] First, the collected instrument image is converted into a grayscale image, and then the grayscale image is binarized to obtain a binary image, and the threshold is set, and the pixels whose grayscale is within the threshold range are the features to be extracted.

[0029] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0030] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the characteristic value of the meter includes the contour line of the meter, the outline of the internal pointer, and the contour of the scale line; when the characteristic values ​​of the meter are consistent, use image two The value-based processing method extracts the digital outline of the batch number in the instrument image for comparison, and different batches correspond to different instrument programs.

[0031] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an automobile instrument program adaptive downloading system and method based on a graphic comparison mode, relates to automobile instrument program adaptive downloading systems and methods and aims to solve the problem that existing instrument program downloading is low in accuracy due to excessive manual operation. The method comprises the steps that an image processing technology is adopted, and a feature value of an instrument is extracted and input into an instrument information input module of a computer; the feature value input into the computer is associated and locked with a corresponding instrument program to form a database formation module of a database; a program-to-be-copied instrument is connected with the computer, and information is transmitted to a program-to-be-copied instrument information collection module in the computer; a program-to-be-copied instrument model analysis module of a program associated and locked with the program-to-be-copied instrument is found in the database and displayed; and the found program which is associated and locked with the program-to-be-copied instrument is automatically downloaded to a program downloading module in the program-to-be-copied instrument. The automobile instrument program adaptive downloading system and method are applied to the field of instrument program downloading.

Description

technical field [0001] The invention relates to a system and method for self-adaptive downloading of automobile meter programs based on a graphic comparison mode. Background technique [0002] At present, due to the wide variety of automotive instrument models and different parameters, when downloading the instrument program, according to the process guidance document, the operation is compared, and there are too many human operations. When various instruments are produced, there will be a risk that the instrument program download will be confused. The existing production method not only has the disadvantages of high labor intensity, error-prone, low efficiency and inconvenient management, but also does not meet the requirements of large-scale batch production. Therefore, it is a problem to be solved in the prior art to find an instrument program download method that is fast, accurate and adaptable to the requirements of mass production. Contents of the invention [0003]...
