What Is the Difference Between Hard Recognition System and Soft Recognition System - Parking Space G

1. Analysis and recognition mode: hard recognition system: video stream analysis and recognition is adopted to conduct all-weather real-time analysis of video stream within the monitoring range; Soft recognition system: image analysis and recognition, take photos of vehicles within the specified range, and then analyze the photos; When the vehicle position is poor, the identification is prone to error. 2. Trigger recognition mode: hard recognition system: ground sense and video trigger are optional. There is no need to add detection equipment, destroy the ground or add projects, and collect images 24 hours. Soft recognition system: triggered by ground sensing, infrared and other peripheral vehicle detection equipment; Certain quantities are required. 3. Recognition speed: hard recognition system: the vehicle license plate recognition speed is less than 0.4 seconds, which fully meets the needs of large traffic flow; Soft recognition system: the vehicle license plate recognition speed is greater than 3 seconds or even longer, which is unbearable. 4. Speed adaptability: hard recognition system: the speed can be recognized stably and quickly within the range of 0-120km / h; It has a wide range of applications and can be used in high-speed kilometers. Soft recognition system: when the vehicle speed is greater than 40km / h, the recognition rate decreases sharply. It is now introduced into the parking lot system and needs to be further improved. 5. Environmental adaptability hard recognition system: it can work normally under various lighting conditions such as night, cloudy day and rainy day; Soft recognition system: under the above conditions, even at different times of the day, the recognition accuracy fluctuates greatly. 6. Compatibility hard recognition system: without the support of industrial IO card, the via parking lot control system (PLC) can be directly and seamlessly compatible with all kinds of IC, ID, paper ticket and other parking lots, so as to realize the functions of automatic recognition and automatic printing of license plate number when the license plate number and card number must be consistent. Soft identification system: it relies on Io card for vehicle detection, opening and closing of road gates and other actions, which is only embedded in software and has no connection with hardware. Large quantities, many lines and poor stability. 7. Camera sharing hard recognition system: the system can share cameras with the monitoring system without any impact on the system. Soft recognition system: it cannot be shared, otherwise it will seriously affect the system stability and recognition rate. 8. Output signal hard identification system: the system can output real-time data such as large picture of vehicle, small picture of number plate, number plate identification number, number plate color and identification reliability, traffic flow, parking volume in the yard, etc. It has the function of static picture query for vehicle access, connecting parking space guidance system, etc.
