For now, more and more parking lots will choose to use the automatic number plate recognition camera. Normally, a complete automatic number plate recognition camera mainly includes several parts: vehicle detection, image acquisition and license plate recognition. Its core computing methods include: license plate positioning algorithm, license plate character segmentation algorithm and optical character recognition algorithm.
Of course, in the choice of automatic number plate recognition camera, you can choose according to the specific circumstances. At present, it mainly includes three kinds of recognition modes, namely: video recognition mode, ground sense coil recognition mode and video and ground recognition mode. Usually when the vehicle reaches the detection area, the detection system will trigger the image acquisition unit for information collection, this time the camera will recognize the current video image acquisition.
Next, let's take a brief look at the different characteristics of the three different recognition modes. First, let's see what is the video recognition mode. The main advantage of this model is that you do not need to use the sense of the coil, the construction is convenient. When the vehicle enters the video recognition area, the automatic number plate recognition camera automatically recognizes the license plate information according to the dynamic image of the vehicle while providing simulation trigger identification.
So what is the advantage of the sense coil recognition mode? In contrast, the performance of this model is more stable, high triggering rate, generally do not appear leakage problems. Usually in the vehicle into the recognition area, it will trigger the sense of the coil, this time the automatic number plate recognition camera will be captured, and then through the character detection, after the identification of the comparison will be released.
The last model is superior in performance, because this model is actually the above two modes of upgrade mode. That is, it can provide faster recognition speed and higher recognition rate. When the vehicle reaches the recognition area, the automatic number plate recognition camera will easily record and identify the vehicle information.
