Pedestrian detection and motion prediction with rear-facing camera
First Claim
Patent Images
1. A method comprising:
- receiving one or more images from a rear-facing camera on a vehicle facing in a rearward direction;
determining, by a computer system, that a pedestrian is present in the one or more images;
predicting, by the computer system based on the one or more images, future motion of the pedestrian;
evaluating the future motion of the pedestrian with respect to a path of the vehicle in a forward direction opposite the rearward direction;
determining (a) that the future motion of the pedestrian is in conflict with the path of the vehicle in the forward direction; and
in response to (a), notifying, by the computer system, a driver-assistance or automated driving system that a conflict exists between forward motion of the vehicle and the future motion.

Abstract
Systems, methods, and devices for pedestrian detection are disclosed herein. A method includes receiving one or more images from a rear-facing camera on a vehicle. The method further includes determining that a pedestrian is present in the one or more images, predicting future motion of the pedestrian, and notifying a driver-assistance or automated driving system when a conflict exists between forward motion of the vehicle and the predicted future motion of the pedestrian.

11. A method for detecting pedestrians comprising:
- receiving one or more images from a rear-facing camera on a vehicle, the one or more images being captured while the vehicle is in a forward gear;
identifying, by a first neural network of a computer system, the one or more images to determine one or more regions where pedestrians are likely located within the one or more images;
determining, by a second neural network of the computer system, that a pedestrian is present in at least one of the one or more regions;
predicting, by the computer system based on the one or more images, future motion of the pedestrian, the predicted future motion comprising motion outside of the view of the rear- facing camera;
evaluating, by the computer system, the future motion of the pedestrian with respect to a path of the vehicle in a forward direction;
determining, by the computer system, (a) that the future motion of the pedestrian is in conflict with the path of the vehicle in the forward direction; and
in response to (a), notifying, by the computer system, a driver-assistance or automated driving system that a conflict exists between forward motion of the vehicle and the predicted future motion. - View Dependent Claims (12, 13, 14)
- receiving one or more images from a rear-facing camera on a vehicle, the one or more images being captured while the vehicle is in a forward gear;

15. A system comprising:
- a rear-facing camera positioned on a vehicle to capture one or more images of a region behind the vehicle;
a saliency component configured to process the one or more images using a first neural network to generate one or more low resolution saliency maps indicating one or more regions where pedestrians are most likely located within the one or more images;
a detection component configured to process the one or more regions using a second neural network to determine, for each of one or more regions, whether a pedestrian is present;
a prediction component configured to process the one or more images to predict future motion of one or more pedestrians captured in the one or more images; and
a notification component configured to- evaluate the future motion of the pedestrian with respect to a path of the vehicle in a forward direction;
when (a) the future motion of the pedestrian is in conflict with the path of the vehicle in the forward direction, provide a notification indicating a conflict between forward motion of the vehicle of the predicted future motion of the one or more pedestrians. - View Dependent Claims (16, 17, 18, 19, 20)
