Cámara IP del vehículo IPC - 6P Red Digital HD Monitoreo automotriz
Integración del ISP en el control de dominio
Otra tendencia obvia para las cámaras es la integración de los ISP en el control de dominio. 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
Tendencia 3: Cancelar el ISP
La última tendencia es cancelar el ISP y usar datos en bruto directamente (RAWDATA). Pero actualmente todavía hay relativamente pocos métodos utilizados
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 processingEn lugar de utilizar datos en bruto (RAWDATA) para la inferencia sin procesamiento ISP estos datos pueden ser retenidos para mejorar la capacidad de percepción en estas escenas
Pero cancelar un ISP no es tan fácil por un lado, la cantidad de datos RAW es demasiado grande, y la presión de ancho de banda para almacenamiento de transmisión, 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
