Problems solved by technology

[0002] When the car is started, the boot logo of the car will occasionally appear abnormal, such as not displaying, splashing, freezing, etc., because the display of the dynamic logo is different from the principle of ordinary video playback, and this kind of market feedback is common but the probability of recurrence is extremely low The problem is very troubled by the test, and the tester even needs to repeat the operation tens of thousands of times to reproduce the problem

Embodiment

[0034] This embodiment provides a method for automatically detecting defects of a dynamic logo, such as figure 1 shown, including:

[0035] Power on the prototype to be tested and play the dynamic logo;

[0036] According to the frame rate played by the dynamic logo, use the NI vision Acquisition tool to set the camera to the corresponding frame rate for acquisition (generally 30 / 60 frames), the acquisition time is the length of the boot time, and save the picture after the acquisition is completed;

[0037] Read the stored picture information, analyze the collected pictures frame by frame, and then conduct the second round of testing after the analysis is completed, such as figure 2 As shown, image analysis includes:

[0038] Read the picture and obtain the color gamut of the picture; distinguish the image type according to the proportion of the color gamut, and the image type includes non-logo pictures, dynamic logo pictures, and static logo pictures;

[0039] Analyze th...

Abstract

The invention discloses a method for automatically detecting defects of a dynamic logo. The method comprises that following steps that: step one, a to-be-detected prototype is electrified and a dynamic logo is played; step two, according to a frame rate of dynamic logo playing, a camera is set to be at a corresponding frame rate to carry out image information collection and storage; and step three, the stored image information is read and frame-by-frame analysis is carried out on the collected image; to be specific, the image analysis includes: reading the image and acquiring a colour gamut ofthe image; distinguishing the image type being one of a non-logo image, a dynamic logo image, and a static logo image based on the colour gamut proportion; analyzing the colour gamut of the image, carrying out color gamut difference comparison to determine a result; to be specific, carrying out image stuck defect analysis and splash screen defect analysis on a dynamic logo image and then carryingout splash screen defect analysis on the static logo image; and then returning a test result and storing correspondingly collected image information in an abnormal state of the test result. Therefore, automatic detection of the dynamic logo is realized; the product quality is guaranteed; and the test efficiency is improved.

Description

technical field [0001] The invention relates to the field of vehicle electronics, in particular to an automatic defect detection method for a dynamic logo. Background technique [0002] When the car is started, the boot logo of the car will occasionally appear abnormal, such as not displaying, splashing, freezing, etc., because the display of the dynamic logo is different from the principle of ordinary video playback, and this kind of market feedback is common but the probability of recurrence is extremely low The problem of the test is very troublesome, and the tester even needs to repeat the operation tens of thousands of times to reproduce the problem. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an automatic detection method for dynamic logo defects, which realizes automatic detection of dynamic logos, ensures product quality, improves testing efficiency, and releases human resources. [0004] An automatic de...
