偉詮電子推出用於ADAS應用的WT8911智慧鏡頭處理器
2017-09-26
偉詮電子(TAIEX: 2436)今(26)天宣布推出WT8911智慧鏡頭處理器,它是一款適用於先進駕駛輔助系統(ADAS)的解決方案,此方案具精簡及低能耗特性,可整合至車用鏡頭模組。 | |
WT8911為一高效能先進駕駛輔助系統(ADAS)處理器,內含可運行達200MHz的 32位元精簡指令集的CPU/DSP,另有完整豐富的視覺處理功能及介面,包含縮放器(scaler)、扭曲校正、影像遮罩(image mask)、光流偵測等功能。ADAS功能包括車道偏移警示(Lane-Departure Warning, LDW)、移動物偵測(Moving-Object Detection, MOD)及盲點偵測(Blind-Spot Detection, BSD)等等。 | |
WT8911採用小尺寸的BGA封裝技術,適合應用於須整合視覺處理器的車用智慧鏡頭。它還可以做為WT8893S 環車影像(AVM)處理器的協處理器、進行ADAS影像偵測工作確保駕駛者的行車安全。WT8911已通過汽車電子委員會(AEC) Q100 (Grade 2)驗證規範。 | |
