车辆检测可以采用埋地线圈检测、红外检测、雷达检测技术、视频检测等多种方式。采用视频检测可以避免破坏路面、不必附加外部检测设备、不需矫正触发位置、节省开支,而且更适合移动式、便携式应用的要求。
Vehicle detection can use buried coil detection, infrared detection,
radar detection technology, video detection and other methods. The use
of video detection can avoid damaging the road, without additional
external detection equipment, without correcting the trigger position,
save money, and is more suitable for mobile and portable applications.
系统进行视频车辆检测,需要具备很高的处理速度并采用优秀的算法,泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊生产线玻璃钢拍门在基本不丢帧的情况下实现图像采集、处理。若处理速度慢,则导致丢帧,使系统无法检测到行驶速度较快的车辆,同时也难以保证在有利于识别的位置开始识别处理,影响系统识别率。因此,将视频车辆检测与牌照自动识别相结合具备一定的技术难度。
For video vehicle detection, the system needs high processing speed and
excellent algorithm to achieve image acquisition and processing without
losing frames. If the processing speed is slow, it will lead to frame
loss, which makes the system unable to detect fast vehicles. At the same
time, it is difficult to ensure that the recognition processing starts
at the position conducive to recognition, which affects the recognition
rate of the system. Therefore, it is difficult to combine video vehicle
detection with license plate recognition.
