TDAx ADAS SoCs – Surround view
The automotive surround view camera system is an emerging automotive advanced driver assistance system (ADAS) technology that assists the driver in parking the vehicle safely by providing a 360 degree bird's eye view of the vehicle surroundings using multiple cameras, usually 4 to 6 wide angled cameras (fish-eye lens).
The automotive 3D surround view provides enhanced visibility from multiple camera angles around the car while parking and maneuvering in different situations.
TI Jacinto TDAx automotive processors addresses the key needs of the surround view system such as safety, convenience and autonomous features. In addition, TI provides complete hardware and software scalability enabling easy development of optimized solutions and faster time to market.
TI provides multiple evaluation and development kits including a versatile Software Development Kit (SDK) to enable customers to get started quickly on TI platforms.
