Sensor Configuration and Coordinate System Transforms

Camera sensor configuration, image-to-vehicle coordinate system transform, bird’s-eye-view image transform

You can use the monoCamera object to define your monocular camera configuration. The object requires you to define camera intrinsics and extrinsics. To obtain intrinsics, use the Camera Calibrator app. Extrinsics are defined by specifying the camera mounting position. You can use the configured monoCamera object to transform locations in image coordinates to locations in vehicle coordinates. These transformations enable you to estimate distances to locations ahead of the ego vehicle. You can also create a bird’s-eye-view image using the monoCamera object.
