Assignee: INTEL CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  B | IPC B  G

Claim 7:
8. A device configured to calculate a time to contact for an autonomous vehicle, the device comprising one or more processors configured to:
obtain a reference signal frequency of a transmitted light that has been modulated by the reference signal frequency and emitted toward a scene;
obtain a change in a light intensity of at least one pixel, wherein the at least one pixel is part of an image of the scene reflecting the transmitted light;
determine a frequency of the change in the light intensity of the at least one pixel over time;
determine an object based on the at least one pixel and based on a comparison between the reference signal frequency and the frequency of the change in the light intensity, wherein the object is defined by a fully enclosed bounding box comprising coordinates of a rectangular border;
calculate a distance between a set of coordinates of the bounding box closest to the autonomous vehicle and the autonomous vehicle;
calculate the time to contact between the set of coordinates of the bounding box and the autonomous vehicle; and
control a movement of the autonomous vehicle based on the time to contact.
