3G/4G Transmission API SDK Provide People Counter System

3G/4G Transmission API SDK Provide People Counter System Real-Time Wifi Transfer GPS Positioning Passenger Counter

   Sodimax Video-Counting Bus People Counter(VPC) with binocular lens is developed by adopting advanced Video stereoscopic Recognition Technoloy.It judges passenger’s number by capturing human characteristics such as head, shoulders, body and body’s get-on& get-off Movement characteristics and obtains accurate counting results by high-speed DSP intelligent algorithm.After many years’ improvement and development, the core calculation working way has been successfully used in different application scenarios and vehicles. Normally the accuracy of statistics is over 98% and with crowded circumstances, the accuracy is over 95%. It can automatically filter backpack, luggage etc.
