摘要

Systems and methods are described for Distification of 3D imagery. A computing device may obtain a three dimensional (3D) image that includes rules defining a 3D point cloud used to generate a two dimensional (2D) image matrix. The 2D image matrix may include 2D matrix point(s) mapped to the 3D image, where each 2D matrix point can be associated with a horizontal coordinate and a vertical coordinate. The computing device can generate an output feature vector that includes, for at least one of the 2D matrix points, the horizontal coordinate and the vertical coordinate of the 2D matrix point, and a depth coordinate of a 3D point in the 3D point cloud of the 3D image. The 3D point can have a nearest horizontal and vertical coordinate pair that corresponds to the horizontal and vertical coordinates of the at least one 2D matrix point.

說明書

In certain embodiments, the 3D images used to generate the prediction model may depict driver behaviors. The driver behaviors can include, for example, driver gestures such as: left hand calling, right hand calling, left hand texting, right hand texting, eating, drinking, adjusting the radio, or reaching for the backseat. The prediction model may determine a driver behavior classification and corresponding probability value for a 3D image, where the probability value can indicate the probability that the 3D image is associated with a driver behavior classification, e.g., “eating.” The 3D image may then be associated with the driver behavior classification, such that the 3D image is said to identify or otherwise indicate the driver behavior for the driver.

In some embodiments, the driver behavior classification and the probability value can be transmitted to a different computing device, such as a remote computing device or a local, but separate computing device.
