ADAS Coordinate Systems

ADAS (Advanced Driver Assistance Systems) typically use several different coordinate systems to accurately capture and analyze data from a vehicle and its surroundings. Here are some of the most common ADAS coordinate systems:

1. Global Positioning System (GPS) coordinates: These are used to locate the vehicle on a map, and can be used for navigation and routing.

2. Inertial Measurement Unit (IMU) coordinates: These are used to measure the vehicle's acceleration, velocity, and orientation relative to a fixed reference frame.

3. Vehicle coordinates: These are used to describe the position and orientation of the vehicle relative to its own frame of reference.

4. Camera coordinates: These are used to describe the position and orientation of cameras installed on the vehicle, relative to the vehicle's frame of reference.

5. Lidar coordinates: These are used to describe the position and orientation of lidar sensors installed on the vehicle, relative to the vehicle's frame of reference.

6. Map coordinates: These are used to describe the position and orientation of objects in the environment relative to a fixed map, and are often used for path planning and obstacle detection.
