This invention discloses an
automatic identification system for digital instrument testing, comprising an
image acquisition module, an image preprocessing module, a
character recognition module, a data judgment module, a
data processing module, and a
certificate generation module. The invention acquires the reading window image of the digital instrument under test through the
image acquisition module, and automatically extracts and parses the displayed
digital content by combining image preprocessing and
character recognition algorithms. This achieves non-intrusive reading without requiring any hardware or
software modifications to the tested digital instrument, making it applicable to most digital instruments. The invention connects the
image acquisition module locally to a computer, avoiding the risks of privacy violations and data leaks associated with using webcams. Furthermore, the invention ensures standardized
operating procedures and accurate data collection by performing automated logical
verification on the identified digital information. This invention achieves automated and standardized reading, improves the testing efficiency of digital instruments, and eliminates
human error.
