Problems solved by technology

Although robot intelligent inspection has the advantages of being all-weather and not affected by harsh environments, there are still many problems in the existing methods for digital instrument positioning and digital identification
For example, the recognition method based on character segmentation and template matching cannot effectively deal with oblique images, and requires high-resolution input images, so the method is greatly affected by environmental noise
Moreover, many high-precision digital instruments will inevitably have a decimal point and its position is not fixed, and there may be multiple rows of numbers on one instrument.
