Problems solved by technology
For example, in products such as lithium batteries, if the performance of the product is not up to standard, it will often cause problems such as reduced service life, swelling, or even explosion due to self-heating or overheating of the use environment.
However, in the prior art, the performance detection method of the product is usually static detection in a normal environment, which cannot detect the change characteristics of the internal structure of the lithium battery under certain external factors such as pressurization, heating, charging and discharging, etc. Make a reasonable estimate of the quality of the product after it is put into use

The embodiment of the present application discloses a thermal radiation-based performance detection method and detection system. The detection method uses thermal radiation to control the temperature of the object to be detected, by emitting a ray beam to the object to be detected; receiving the ray beam emitted to the object to be detected, and generating a document for recording the object to be detected according to the ray beam The digital image of the outline of the object, and then merge the digital images to generate a contour line deformation map corresponding to the object to be detected; and according to the contour line deformation map and a preset comparison image, The object to be detected is detected and analyzed to obtain the detection result. Therefore, the dynamic performance detection of the object to be detected is realized, and the performance of the object to be detected at different temperatures is detected by using thermal radiation, which is beneficial to improving the reliability of performance detection.
Description
technical field [0001] The present application relates to the technical field of detection, and in particular, to a thermal radiation-based performance detection method and detection system. Background technique [0002] In modern industrial production activities, performance testing of products is an essential production link. For example, in products such as lithium batteries, if the performance of the product does not meet the standard, problems such as reduced life, bulging, and even explosion of the product are often caused by self-heating or overheating of the operating environment. However, in the prior art, the performance detection method of the product usually adopts the static detection in the normal environment, which cannot detect the change characteristics of the internal structure of the lithium battery under certain external factors such as pressure, heating, charging and discharging, etc. Make a reasonable estimate of the quality of the product after it is ...
