The invention discloses a detection method of a laminated lithium-ion battery, which comprises the steps of: by counting the variance of each line of the gray scale image of the laminated battery in the horizontal direction, performing threshold value processing on the statistical results to determine the characteristic area for measurement; The feature area image of the image is used for corner detection, the similarity of each point of the image is calculated, and the direction change intensity is calculated, and the threshold is set according to the direction change intensity to filter the corner position of the image, that is, corner point detection; by counting the above corner points in the horizontal direction The maximum occurrence probability of the positive and negative poles is used to classify the corner points; after determining the position with the highest probability of occurrence of the positive and negative pole corners, the maximum position is used as a reference point to screen the positive and negative pole corners, and after screening, perform cubic fitting. During the fitting, the position with large vacancy is compensated. Improve the efficiency and accuracy of stacked lithium ion detection.
Description
technical field [0001] The invention relates to the field of lithium battery detection, in particular to a detection method for laminated lithium ion batteries. Background technique [0002] The global lithium-ion battery industry for consumer electronics was pioneered by Japan. After entering 2005, China's industry rose, and China, Japan and South Korea emerged as a three-point world. In 2011, the "Energy Conservation and New Energy Vehicle Development Plan" issued by the State Council mentioned that in the next 10 years, the state will invest 100 billion yuan to support the development of the new energy industry, and lithium power batteries will develop rapidly in the next few years. According to the research report on the development of China's battery industry, driven by the enthusiasm for new energy batteries, the cumulative output of lithium-ion batteries nationwide in 2011 was 2.955 billion, a year-on-year increase of 18.14%. [0003] However, the repeated fires and ...
