Displaying sensor data and supplemental data as a mask for autonomous vehicles
Aspects of the disclosure relate to providing sensor data on a display of a vehicle. For instance, data points generated by a lidar sensor may be received. The data points may be representative of one or more objects in an external environment of the vehicle. A scene including a representation of the vehicle from a perspective of a virtual camera, a first virtual object corresponding to at least one of the one or more objects, and a second virtual object corresponding to at least one object identified from pre-stored map information may be generated. Supplemental points corresponding to a surface of the at least one object identified from the pre-stored map information may be generated. A pulse including at least some of the data points generated by the sensor and the supplemental points may be generated. The scene may be displayed with the pulse on the display.
1. A method of providing sensor data on a display of a vehicle, the method comprising:
receiving, by the one or more processors, data points generated by a lidar sensor representative of one or more objects in an external environment of the vehicle;
generating, by the one or more processors, a scene including a representation of the vehicle from a perspective of a virtual camera, a first virtual object corresponding to at least one of the one or more objects, and a second virtual object corresponding to at least one object identified from pre-stored map information;
generating, by the one or more processors, supplemental points corresponding to a surface of the at least one object identified from the pre-stored map information;
generating, by the one or more processors, a mask including at least some of the data points generated by the sensor and the supplemental points, and a plurality of rings; and
displaying, by the one or more processors, the scene with the mask on the display, wherein displaying the mask includes highlighting the at least some the supplemental points once a ring of the plurality of rings contacts a surface of the second virtual object.
2. The method of claim 1 , wherein the supplemental points are not points corresponding to actual sensor data provided by a perception system of the vehicle including the lidar sensor.
3. The method of claim 1 , wherein the plurality of rings are concentric about the vehicle from a top-down perspective.
4. The system of claim 3 , wherein the plurality of rings are concentric about the vehicle from a top-down perspective.
5. The method of claim 1 , wherein displaying the mask includes displaying the plurality of rings such that the rings appear to emanate from the vehicle.
6. The method of claim 1 , wherein displaying the mask includes displaying portions of the plurality of rings only when such portions contact the first virtual object.
7. The method of claim 1 , wherein displaying the video includes fading the plurality of rings away over a period of time.
8. The method of claim 1 , wherein the first virtual object is a road user.
9. The method of claim 1 , wherein the at least one object is a building.
10. The method of claim 1 , wherein the at least one object is a lane marker.
11. The method of claim 1 , wherein generating the supplemental points includes generating one or more lines for a surface of the second virtual object.
12. The method of claim 1 , wherein generating the supplemental points includes identifying intersection points of two or more sets of perpendicular lines overlaid on a surface of the second virtual object.
13. The method of claim 1 , wherein generating the supplemental points includes identifying points of a grid overlaid on a surface of the second virtual object.
14. A system of providing sensor data on a display of a vehicle, the system comprising one or more processors configured to:
receive data points generated by a lidar sensor representative of one or more objects in an external environment of the vehicle;
generate a scene including a representation of the vehicle from a perspective of a virtual camera, a first virtual object corresponding to at least one of the one or more objects, and a second virtual object corresponding to at least one object identified from pre-stored map information;
generate supplemental points corresponding to a surface of the at least one object identified from the pre-stored map information;
generate a mask including at least some of the data points generated by the sensor and the supplemental points, and a plurality of rings; and
display the scene with the mask on the display, wherein displaying the mask includes highlighting the at least some the supplemental points once a ring of the plurality of rings contacts a surface of the second virtual object.
15. The system of claim 14 , wherein the simulated points are not points corresponding to actual sensor data provided by a perception system of the vehicle, including the lidar sensor.
16. The system of claim 14 , further comprising the vehicle.
