Abstract

Apparatus, systems, and methods for perceiving objects in an environment in three dimensions are provided. One apparatus includes a turntable capable of being coupled to a vehicle and a light detection and ranging (LIDAR) device mounted on the turntable. A system includes a vehicle with a turntable coupled to the vehicle and a LIDAR device mounted on the turntable. One method includes rotating a two-dimensional LIDAR device along an axis of rotation that is substantially normal to a ground plane beneath the vehicle, capturing data points of objects within the environment surrounding the LIDAR device, and generating a three-dimensional representation of the objects based on the data points.

Claims

1. A perception apparatus for a vehicle, comprising:

a turntable capable of being coupled to the vehicle; and

a light detection and ranging (LIDAR) device mounted on the turntable.

2. The perception apparatus of claim 1, wherein the LIDAR device is mounted on a perimeter of the turntable.

3. The perception apparatus of claim 1, wherein the LIDAR device is mounted at a location between a center and a perimeter of the turntable.

4. The perception apparatus of claim 1, wherein the turntable is capable of being mounted on the vehicle such that the turntable includes an axis of rotation that is substantially normal to a ground plane beneath the vehicle.

5. The perception apparatus of claim 4, wherein the LIDAR device is mounted at an angle below horizontal with respect to the turntable.

6. The perception apparatus of claim 4, wherein the LIDAR device is mounted at an angle above horizontal with respect to the turntable.

7. The perception apparatus of claim 1, further comprising an adjustable mounting means coupled to the turntable, wherein the LIDAR is mounted to the adjustable mounting means and the mounting means is configurable to modify an angle at which the LIDAR device is pointed.

15. The perception and navigation system of claim 5, wherein the LIDAR device is mounted at a location between a center and a perimeter of the turntable.

8. A perception and navigation system, comprising:

a vehicle;

a turntable coupled to the vehicle; and

a light detection and ranging (LIDAR) device mounted on the turntable.

9. The perception and navigation system of claim 8, wherein the turntable is coupled to the vehicle such that an axis of rotation of the turntable is normal with respect to a ground plane beneath the vehicle.

10. The perception and navigation apparatus of claim 9, wherein the LIDAR device is mounted at an angle below horizontal with respect to the axis of rotation.

11. The perception and navigation apparatus of claim 9, wherein the LIDAR device is mounted at an angle above horizontal with respect to the axis of rotation.

12. The perception and navigation apparatus of claim 9, further comprising an adjustable mounting means coupled to the turntable, wherein the LIDAR is mounted to the adjustable mounting means and the mounting means is configurable to modify an angle at which the LIDAR device is pointed with respect to the axis of rotation.

13. The perception and navigation system of claim 8, wherein the LIDAR device is mounted on a perimeter of the turntable.

14. The perception and navigation system of claim 8, wherein the LIDAR device is mounted on a center of the turntable.

16. An object perception method for a vehicle in an environment having a ground, the perception and navigation method comprising the steps of:

rotating a two-dimensional light detection and ranging (LIDAR) device along an axis of rotation that is substantially normal to a ground plane beneath the vehicle;

capturing data points of objects within the environment surrounding the LIDAR device; and

generating a three-dimensional representation of the objects based on the data points.

17. The object perception method of claim 16, wherein the rotating step comprises the step of rotating the LIDAR device greater than 180 degrees along the axis of rotation.

18. The object perception method of claim 16, wherein the rotating step comprises the step of rotating the LIDAR device 360 degrees along the axis of rotation.

19. The object perception method of claim 16, wherein the rotating step comprises the step of rotating the LIDAR device in a single direction along the axis of rotation.

20. The object perception method of claim 16, further comprising the step of translating the LIDAR device while the LIDAR device is rotating along the axis of rotation.
