차량 IP 카메라 IPC - 6P 네트워크 디지털 HD 자동차 모니터링
도메인 제어에 ISP 통합
카메라의 또 다른 명백한 경향은 ISPs가 도메인 컨트롤에 통합되는 것입니다. 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
트렌드 3: ISP를 취소
마지막 트렌드는 ISP를 취소하고 RAWDATA를 직접 사용하는 것입니다.
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 처리 없이 추론을 위해 원형 데이터 (RAWDATA) 를 사용하는 대신 이 데이터는 이러한 장면에서 인식 능력을 향상시키기 위해 유지 될 수 있습니다
하지만 ISP를 취소하는 것은 그렇게 쉬운 일이 아닙니다. 한편으로는, RAWDATA의 양은 너무 크고, 전송 저장에 대한 대역폭 압력은 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
