Abstract

The application provides a lottery information non-contact recognition method and device based on multi-mode optical imaging, which comprises the following steps: step 1, starting an infrared backlight light source, controlling the light path conduction through a mechanical light shield, collecting an infrared transmission image of the lottery, and locating a key information area based on the difference in infrared transmission characteristics of different areas; step 2, in the key information area, sequentially switching the light path through the mechanical light shield, respectively conducting a ring-shaped diffuse normal light source and a low-angle grazing light source, and collecting at least two visible light images by using orthogonal polarization extinction structure; and step 3, taking the at least two visible light images as input, inputting a lightweight OCR engine to complete the lottery information recognition after processing by a preset strategy, so that the most suitable image for recognition is captured at the physical level through the innovative multi-spectral light source configuration, orthogonal polarization extinction technology and mechanical light source time sequence control, thereby greatly simplifying the back-end processing.
