Nvidia patents method for cars to detect parking spots using mixed data
Nvidia describes a system that helps self-driving vehicles find parking spaces by combining visual edge detection with machine learning predictions. The technology filters out background noise from sensor data to create a precise map of the parking area's shape. This final map allows the vehicle to accurately navigate and park within the designated space.
In the filing’s own words
In various examples, parking area detection for autonomous and/or semi-autonomous systems and applications is described herein. Systems and methods described herein may use a hybrid method to more accurately determine geometries of the parking areas within environments. For instance, sensor data (e.g., image data, etc.) may be processed using one or more edge detection techniques to determine edge features (e.g., two-dimensional pixels, three-dimensional points, etc.) associated with an environment that includes a parking area. A predicted geometry associated with the parking area, as determined using one or more machine learning models, may then be used to filter the edge features in order to identify a portion of the edge features that represent the parking area. One or more optimization techniques may then be used to determine the final geometry associated with the parking area based at least on the filtered edge features.
What exactly they claim (claim 1)
1. A method comprising: determining, using one or more machine learning models and based at least on first sensor data, a first geometry associated with a parking area; determining, based at least on second sensor data, first points associated with an environment that includes the parking area; determining, based at least on filtering out at least a portion of the first points that are outside of a threshold distance to the first geometry, one or more second points associated with one or more edges of the parking area; determining, based at least on the one or more second points, a second geometry associated with the parking area; and causing a machine to perform one or more operations based at least on the second geometry associated with the parking area.
