specific Embodiment approach 1

[0022] Specific implementation mode one: as figure 1 Shown, a kind of car instrument program self-adaptive downloading system based on graphic comparison mode includes:

[0023] 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;

[0024] A database forming module for associating and locking the characteristic values ​​input into the computer with the corresponding instrument aging program to form a database;

[0025] It is used to connect the aging meter to the computer, collect the image of the aging meter through the camera, and transmit the information to the information acquisition module of the aging meter in the computer;

[0026] The instrument model analysis module to be aged is used to analyze the model of the instrument to be aged, find and display the program associated with the aged instrument to be locked in the database;

[0027] The progr...

specific Embodiment approach 2

[0028] Specific implementation mode two: the difference between this implementation mode and specific implementation mode one is: the image processing technology is specifically:

[0029] 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.

[0030] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0031] 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 contour line of the batch number in the instrument image for comparison, and different batches correspond to different instrument aging procedures.

[0032] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a system and method for self-adaptively downloading automobile instrument aging processes on the basis of a graphic comparison mode, relates to a system and method for self-adaptively downloading instrument aging processes, and aims at solving the problem that the existing downloading of instrument aging processes is relatively low in correctness due to excessive manmade operations. The system comprises an instrument information input module, a database forming module, a to-be-aged instrument information acquisition module, a to-be-aged instrument model analysis module and a process downloading module, wherein the instrument information input module is used for adopting an image processing technology to extract feature values of instruments and inputting the feature values into a computer; the database forming module is used for associating and locking the feature values input in the computer with corresponding instrument aging processes to form a database; the to-be-aged instrument information acquisition module is used for connected to-be-aged instruments with the computer and transmitting information into the computer; the to-be-aged instrument model analysis model is used for finding and displaying processes associated and locked with the to-be-aged instruments in the database; and the process downloading module is used for automatically downloading the found processes associated and locked with the to-be-aged instruments into the to-be-aged instruments. The system and method disclosed by the invention are used for the field of instrument aging process downloading.

Description

technical field [0001] The invention relates to a self-adaptive downloading system and method for an aging program of an automobile meter 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 aging program, according to the process guidance document, the comparison operation, too many manual operations, there is a risk of inconsistent aging settings during the production of various instruments. The aging time and aging temperature required by different instruments are different. Appropriate settings are required. [0003] 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 aging program download me...
