Abstract: One variation of a method includes: accessing a 2D color image recorded by a 2D color camera and a 3D point cloud recorded by a 3D depth sensor at approximately a first time, the 2D color camera and the 3D depth sensor defining intersecting fields of view and facing outwardly from an autonomous vehicle; detecting a cluster of points in the 3D point cloud representing a continuous surface approximating a plane; isolating a cluster of color pixels in the 2D color image depicting the continuous surface; projecting the cluster of color pixels onto the plane to define a set of synthetic 3D color points in the 3D point cloud, the cluster of points and the set of synthetic 3D color points representing the continuous surface; and rendering points in the 3D point cloud and the set of synthetic 3D color points on a display.

Abstract: One variation of a method for accessing supplemental data from other vehicles includes, at an autonomous vehicle: recording a scan image of a scene around the autonomous vehicle at a first time; detecting insufficient perception data in a region of the scan image; in response to detecting insufficient perception data in the region, defining a ground area of interest containing the region and wirelessly broadcasting a query for perception data representing objects within the ground area of interest; in response to receiving supplemental perception data—representing objects within the ground area of interest detected by the second vehicle at approximately the first time—from a second vehicle proximal the scene, incorporating the supplemental perception data into the scan image to form a composite scan image; selecting a navigational action based on objects in the scene represented by the composite scan image; and autonomously executing the navigational action.

Abstract: One variation of a method for communicating state, intent, and context of an autonomous vehicle includes: at a first time, displaying a first icon representing a current state of a vehicle on a rear-facing visual display arranged on the vehicle; navigating toward an intersection; at a second time, detecting a state of the intersection ahead of the vehicle; rendering a second icon representing the state of the intersection at the second time on the rear-facing visual display; detecting a change in the state of the intersection at a third time succeeding the second time; selecting a next navigation action for the vehicle responsive to the change in the state of the intersection at the third time; prior to executing the next navigation action, rendering a third icon representing the next navigation action on the rear-facing visual display; and autonomously executing the next navigation action.

Abstract: One variation of a method for monitoring an interior state of an autonomous vehicle includes: at the autonomous vehicle, recording a pre-ride image of an interior of the autonomous vehicle prior to initiating a ride; following completion of the ride, recording a post-ride image of the interior of the autonomous vehicle; detecting a region of the post-ride image differing from the pre-ride image, the region of the post-ride image representing a change in the interior of the autonomous vehicle following occupancy of the autonomous vehicle by a user; classifying a type of an object depicted in the region of the post-ride image based on features extracted from the region of the post-ride image; and in response to classifying the object depicted in the region of the post-ride image as a personal item, serving a prompt to the user to retrieve the object from the autonomous vehicle.

Abstract: One variation of a method for transferring control of an autonomous vehicle to a remote operator includes: accessing a specification for triggering manual control of autonomous vehicles; identifying a road segment, within a geographic region, exhibiting characteristics defined by the specification; and associating a location of the road segment, represented in a navigation map, with a remote operator trigger. The method also includes, at the autonomous vehicle operating within the geographic region: autonomously navigating along a route; transmitting a request for manual assistance to the remote operator in response to approaching the location associated with the remote operator trigger; transmitting sensor data to a remote operator portal associated with the remote operator; and executing a navigational command received from the remote operator via the remote operator portal; and resuming autonomous navigation along the route after passing the location.

Abstract: One variation of a method for influencing entities proximal a road surface includes, at an autonomous vehicle: over a first period of time, detecting a pedestrian proximal a road surface; predicting an initial path of the pedestrian an initial confidence score for the initial path of the pedestrian based on and motion of the pedestrian during the first period of time; in response to the initial confidence score falling below a threshold confidence, replaying an audio track audible to the pedestrian and calculating a revised path of the pedestrian and a revised confidence score for the revised path based on motion of the pedestrian following replay of the audio track; and autonomously navigating across the road surface according to a planned route in response to the revised path of the pedestrian falling outside of the planned route and the revised confidence score exceeding the threshold confidence.

Abstract: One variation of a method for training and refining an artificial intelligence includes: training a neural network on a training set to identify objects in optical images; receiving a manual label attributed to an optical image—recorded by a road vehicle during its operation—by a human annotator; passing the optical image through the neural network to generate an automated label attributed to the optical image; in response to the manual label differing from the automated label, serving the optical image to a human annotator for manual confirmation of one of the manual label and the automated label; appending the training set with the optical image containing one of the manual label and the automated label based on confirmation received from the human annotator; and retraining the neural network, with the training set, to identify objects in optical images.
