Camera Sensor Configuration

Monocular camera sensor calibration, image-to-vehicle coordinate system transforms, bird’s-eye-view image transforms

When developing a visual perception algorithm for a monocular camera sensor, an accurate camera configuration is essential. You can use a monoCamera object to configure such a sensor by defining its intrinsic and extrinsic parameters. To obtain intrinsic parameters, use the Camera Calibrator app. To obtain extrinsic parameters, use the estimateMonoCameraParameters function. 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 bird's-eye-view images using the monoCamera object, which you can use to verify your camera configuration or as part of a lane detection algorithm.
