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 invention discloses a thermal radiation-based performance detection method and detection system. The detection method comprises the following steps ofperforming temperature control overan object to be detected by using thermal radiation, and transmitting a bundle of rays to the object to be detected; receiving the bundle of rays emitted to the object to be detected, and generating digital images used for recordingthe contour of the object to be detected according to the bundle of rays, then performing merging processing on the digital images to generate a contour line deformation diagram corresponding to the object to be detected; and detecting and analyzing the object to be detectedaccording to the contour line deformation diagram and a preset comparison image to obtain a 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 byusing the thermal radiation, which is beneficial to improving the reliability of the performance detection.
Description
technical field [0001] The present application relates to the technical field of detection, 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 indispensable production link. 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. ...
