Blue Truck Identification System is more suitable for parking
With the growth of China's per capita car ownership, the license plate recognition system has become more and more widely used, and license plate recognition technology has also been correspondingly developed. According to the different applications of license plate recognition, the technical indicators of the license plate recognition system are not the same. The speed of license plate recognition on the highway is very important, but in the parking lot is more emphasis on the accuracy of license plate recognition.
The Blue Truck Identification System is based on advanced machine vision and pattern recognition theory, and is optimized through engineering. It can perform real-time license plate recognition processing on the video and effectively extract the license plate information parameters in the video signal. The license plate recognition method is stable and reliable. The recognition accuracy is greater than 99%.
Apart from providing intelligent analysis functions, the intelligent video server retains the inherent basic functions of the video server, supports the hardware synchronous compression function of video signals and audio signals, compresses the code stream for transmission over the network, can perform network real-time video and audio preview, and supports streaming protocols ( RTP/RTCP), support IE preview, support two-way voice intercom, multi-language support and other functions.
The Blue Truck Identification System Division originally understood:
License plate recognition PTZ camera captures license plate through light suppression screen, electronic shutter adjustment, wide dynamic function, etc.:
Strong light shielding: Based on the low-light color camera, through the function of the software, the brightest part of the image is blocked. In traffic monitoring, the headlights are generally blocked by strong light, so that the license plate can be captured more clearly. However, the disadvantage of this camera is that the software is unclear, and the brightest part of the image is unclear. It is also possible to block the license plate number, and it is impossible to handle the capture of high-speed moving objects. At present, domestic cameras do more in the light shielding, the effect of all parties reflected.
Adjustable electronic shutter: For high-speed movement of objects to capture (the speed of the car on the highway is generally more than 70KM / hour), you can achieve clear capture by reducing the electronic shutter speed, usually through manual adjustment. However, the problem with this method is that the illumination during the day and at night is not the same. It is necessary to set two shutter speeds to adapt to day and night monitoring respectively.
Wide Dynamic Function: This is the solution to the effect of the headlights on the capture. The wide dynamic was originally proposed by Panasonic. When the background light is too bright, ordinary cameras cannot solve the display problem of light and dark images.
As the most important means of identifying vehicle identities in the field of intelligent transportation, license plate recognition technology has played a significant role in realizing the intelligent management of traffic, and it has infiltrated the license plate recognition technology in various works.
