Data is received from one or more radar systems and used to calculate coordinate data, which is processed to estimate parking space boundaries, for which spline estimates are then calculated. These spline estimates are provided to a vehicle computer system. The spline estimates may be Bezier curves or other interpolants, and may be used to detect available parking spaces. The spline estimates may be updated as the vehicle moves, and the radar data may be received at specified time intervals. The radar systems may be positioned at the front or corners of the vehicle. The radar data may be processed using a previously trained neural network, and may be validated using ground truth data. The architecture of the neural network may have several layers, including a loss layer. The neural network may be used to identify a perimeter of radar data and use it to estimate the parking space boundaries.
