ドメイン制御へのISP統合
もう"つの明らかなカメラの傾向は ISPs がドメイン制御に 統合されていることです Under the trend of centralized development in electronic and electrical architecture ECU has shifted from distributed to centralized and cameras have become hardware devices for collecting information Computing and processing functions have been separated from cameras and integrated into high computing power SoCs and domain controllers
With the continuous improvement of ISP performance integrated in SoC it can support the input of multiple cameras so there is no need to install an ISP on each camera module which can greatly reduce hardware costs and solve the heat dissipation problem caused by ISP integration in cameras
トレンド3 ISPをキャンセル
最近の傾向は,ISPをキャンセルし,生データを直接使用することです (RAWDATA).
The raw data of the CAR camera (RAWDATA) is directly input into the neural network without ISP processing which not only reduces costs but also avoids the complex ISP tuning process in the development process and improves visual perception ability
It should be noted that the dynamic range of the camera is much larger than that of the human eye For example in low light or extremely dark scenes the human eye can hardly see it but CMOS can still receive photons to "see" the target However a lot of information is optimized as noise during ISP processing. ISP処理なしで推論のために生データ (RAWDATA) を使用するのではなく,このデータはこれらのシーンの認識能力を改善するために保持することができます
しかしISPをキャンセルするのは 簡単ではありません 一方面では RAWDATAの量が大きすぎて 送信ストレージの帯域幅の圧力が and processing is extremely high On the other hand ISPs are designed to optimize display performance in simple terms for people to see In data links that require human participation (such as labeling) ISPs are still indispensable so ISPs will continue to be retained in the short term
The GPS monitoring car mounted cameras (taxi bus logistics vehicle) designed and manufactured by the company are a new generation of GPS car mounted monitoring cameras that use industrial grade professional video processing Sony chips as the core and integrate functions such as video capture video compression and video storage Suitable for installation in wireless wired GPRS / CDMA and other environments One step in place cost - effective
