The ds-6001hf/p intelligent video server for license plate recognition adopts the license plate recognition technology independently developed by Hikvision, which is realized based on advanced machine vision and pattern recognition theory. After engineering optimization, it can carry out 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, and the accuracy of single character recognition is greater than 99%.
In addition to providing intelligent analysis function, 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, transmits compressed code streams through the network, enables network real-time video and audio preview, supports stream protocol (rtp/rtcp), supports ie preview, supports two-way voice intercom, and supports multiple languages.
Intelligent function of license plate recognition
It supports a variety of vehicle systems. The intelligent video server for license plate recognition can be applied to the license plate recognition of type 92 civil vehicle license plate, type 02 civil vehicle license plate, type 04 military vehicle license plate, police vehicle license plate, type 07 * vehicle license plate and civil vehicle double row tail plate;
Support the recognition of Chinese characters, letters and numbers of license plate;
Support the recognition of license plate color;
Vehicle picture capture;
Support the output of license plate position information;
The identification result statistics and other functions can be developed in combination with the application layer.
Video server functions
