在交通收费和路口监控等车牌识别应用中,纯粹依靠PC机通常难以达到实时性,应用受到了限制,
在将DSP引入到车牌识别应用系统后,此问题可得到较好解决。本DSP系统以TIC6201 DSP处理器为核心,配置
SAA7111A视频解码芯片SAA7111A作为图像输入通道,使用PCI2040实现了DSP以PCI接口方式与PC的通信。
在此系统中,DSP运行识别算法,然后将识别结果通过PCI接口传输给PC供PC进行显示和管理。整个系统计算
分布合理,实时性强,极大提高了实用性
-The application ofLPR in traffic charging and transportationmonitoring always fails towork under
real time requirementwhich producesmuch constraint for furtherutilization. Thisproblem can be improved byuti-
lizingDSP processors. TIC6201 DSP processor can be used as the heartof the system and a video codec chip-
SAA7111A as the forward channel for image inpu.t Besides, PCI2040 functioning as aPCI interface carrieson the
communication between DSP and PC. In the system, C6201 takes the job ofLPR and transmits the result to PC
for display and further datamanagemen.t Thus the system becomesmuchmore practicalwith balanced computa-
tion distribution and the satisfaction of real time functioning.
