Visually indicating vehicle caution regions
First Claim
1. A system comprising:
- a vehicle;
a light projector connected to the vehicle; and
a control system comprising at least one processor and data storage having stored therein computer-readable program instructions, wherein the control system is configured to;
determine a planned operating region for the vehicle within an environment;
determine that the planned operating region is within a threshold distance of an object within the environment;
in response to determining that the planned operating region is within the threshold distance of the object, determine a caution region to illuminate with the light projector near the object;
determine a size of the caution region based on a speed planned for the vehicle within the planned operating region; and
cause the light projector to project an indication of the caution region near the object, wherein the caution region has the determined size, and wherein the projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region.

Abstract
An example system includes a vehicle, a light projector connected to the vehicle, and a control system. The control system is configured to determine a planned operating region for the vehicle within an environment. The control system is also configured to determine that the planned operating region is within a threshold distance of an object within the environment and, in response, determine a caution region to illuminate with the light projector near the object. The control system is further configured to cause the light projector to project an indication of the caution region near the object. The projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region.

1. A system comprising:
-
a vehicle; a light projector connected to the vehicle; and a control system comprising at least one processor and data storage having stored therein computer-readable program instructions, wherein the control system is configured to; determine a planned operating region for the vehicle within an environment; determine that the planned operating region is within a threshold distance of an object within the environment; in response to determining that the planned operating region is within the threshold distance of the object, determine a caution region to illuminate with the light projector near the object; determine a size of the caution region based on a speed planned for the vehicle within the planned operating region; and cause the light projector to project an indication of the caution region near the object, wherein the caution region has the determined size, and wherein the projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A method comprising:
-
determining, by a control system, a planned operating region for a vehicle within an environment; determining, by the control system, that the planned operating region is within a threshold distance of an object within the environment; in response to determining that the planned operating region is within the threshold distance of the object, determining, by the control system, a caution region to illuminate with a light projector near the object, wherein the light projector is connected to the vehicle, wherein the caution region comprises a buffer area near at least part of a perimeter of the object, and wherein determining the caution region comprises; determining an intersection between the planned operating region and a first area, wherein the first area (i) surrounds the perimeter of the object and (ii) is within the threshold distance of the perimeter of the object; determining a second area between the intersection and the perimeter of the object; and combining the intersection and the second area to form the caution region; and causing, by the control system, the light projector to project an indication of the caution region near the object, wherein the projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region. - View Dependent Claims (14, 15)

16. A non-transitory computer readable storage medium having stored thereon instruction that, when executed by a computing device, cause the computing device to perform operation comprising:
-
determining a planned operating region for a vehicle within an environment; determining that the planned operating region is within a threshold distance of an object within the environment; in response to determining that the planned operating region is within the threshold distance of the object, determining a caution region to illuminate with a light projector near the object, wherein the light projector is connected to the vehicle; determining, based on a position of the planned operating region and a position of the object within the environment, a distance between the planned operating region and the object; determining, based on the distance between the planned operating region and the object, a size of the caution region; and providing instructions to cause the light projector to project an indication of the caution region near the object, wherein the caution region has the determined size, and wherein the projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region.
