5-1 結論
本論文已針對行車紀錄器開發一套智慧型危險駕駛辨識系統,並提出一套以 行車紀錄器影像為基礎的即時性辨識系統,實驗結果已顯示駕駛人所行駛的道路 環境包含車道線、車輛追蹤、車距與車速部分都已能夠正確辨識。
藉由精確的即時辨識資訊設計出一套智慧型危險駕駛辨識系統,根據行車環 境分析前方車輛的駕駛行為是否已符合危險駕駛之等級。
對於前方每輛辨識車輛都給予一組狀態表包含:車速、車距以及切換車道頻 率三項標準,藉由所定義的門檻值進行分析。
在超速距偵測部分,利用影像中前方車輛於兩個幀中的移動量計算出前方車 輛車速,當車速大於所在道路的車速限制時,即表示車輛發生超速事件。
在未保持安全偵測部分,根據車道寬度演算法計算前方車輛車距,當前方車 輛進入危險車距範圍內,系統則即時的顯示警示訊息。
由實驗結果可看出系統對於危險駕駛行為的偵測十分精確。
5-2 未來展望
根據本論文所開發的智慧型危險駕駛辨識系統,不同於一般車輛警示系統,
本系統屬於主動式裝置,將會自動辨識前方車輛行為給予駕駛即時性警示功能,
未來藉由結合 VENET/3G 網路將危險駕駛車輛的駕駛資訊包含:所在路段、車牌 與車速等資訊上傳至雲端儲存並且進行回報處理提升行車安全。
