摘要：In the process of the license plate photo recognition process, light and external environmentare important factors for the clarity of the photo result. We first add a 400nm filter in front ofthe camera to carry out the experiment, take pictures with ultraviolet rays light and withoutultraviolet rays light source irradiation, then add a 390nm filter in front of the camera toperform the same experiment for comparison. Perform comparative analysis and imageprocessing on the experimental shooting results. First, it can be seen from the comparison ofthe shooting results that the clarity and recognition of the image under the action of the400nm filter are significantly improved compared with that of the 390nm filter. Second, theimage processing is used to analyze the results, which can eff ectively identify the license plateinformation. Finally, the license plate is irradiated with micro-nano filter and ultraviolet lightsource instead of the monitor fill light, so the strong light stimulation to the driver's eyes isavoided, thereby alleviating the short-term `light blindness' phenomenon of the human eyesand reducing the hidden safety hazards when driving.
