技術簡介
先進駕駛輔助系統(ADAS)可在行車過程中協助駕駛者提
高行車安全性,功能包含車道偏離警告系統(LDWS)、前
方碰撞預警系統(FCWS)、盲點警告系統(BSWS)與四通
道數位行車紀錄器(4Chs DVR)。此軟體解決方案,具
備低成本、高環境適應性與高產品組合性等優點,基於
單張的低解析度影像即可完成即時的物件偵測與辨識,
此外高系統穩定度與低內存使用率的特色亦非常適合車
載的嵌入式應用,即使功能同時運行的情境下,系統依
然能夠保持即時處理與高辨識率。
Abstract
ITRI provides an in house, proprietary
Advanced Driver Assistance System (ADAS)
solution to help the driver improve the car
safety and prevent potential accidents
during the driving process, which includes
lane departure warning system (LDWS),
forward collision warning system (FCWS),
blind spot warning system (BSWS) and four
channels digital video recorder (DVR). Our
object detection method performs image
analysis single frame basis, so real-time
processing can be achieved. Moreover, its
high system stability and low memory usage
make itself very suitable for vehicle
onboard embedded applications. Even features
run simultaneously, the system can still
maintain real time processing while keeps
high detection accuracy. The system is
currently under field-try phase. The testing
results demonstrate high detection accuracy
on freeway, highway, urban streets, and
tunnel driving as well as robustness under
different weather conditions. The system
performance can meet general industrial
standard requirements. Besides, this
hardware design support GPS, microwave
radar, Lidar, multiple Full HD video inputs,
and etc. that can develop next generation
ADAS to prevent more different potential
accidents. Its design and prototype can also
assist domestic companies to seamlessly
adapt to fast-growing and competitive ADAS
applications.
