Abstract
Disclosed herein are methods and systems (sensors) that allow revision of HD maps for lane lines as the lane lines are created. In a non-limiting example, a method comprises receiving, by a processor from a sensor associated with a vehicle configured to paint a lane line, a color attribute, a patterns attribute, and a location of a lane line painted on a road by the vehicle; determining, by the processor, using the location received from the sensor, whether the road has an existing lane line; and revising, by the processor, a high definition map associated with at least one autonomous vehicle by removing the existing lane line from the high definition map and inserting the lane line in the high definition map.
Claims18
A method comprising:
- receiving, by a processor from a sensor associated with a vehicle configured to paint a lane line, a color attribute, a pattern attribute, and a location of the lane line painted on a road by the vehicle;
- determining, by the processor, using the location received, whether the road has an existing lane line;
- revising, in real-time, by the processor, a high-definition digital map associated with at least one autonomous vehicle by removing the existing lane line from the high-definition digital map and inserting the lane line in the high-definition digital map at the time of line painting to enable real-time updates to the high-definition digital map;
- and
- transmitting, by the processor, instructions to an autonomy computing system of an autonomous vehicle to change to a revised high-definition digital map, wherein the autonomy computing system is configured to control operation of the autonomous vehicle to navigate according to the revised high-definition digital map.
A system comprising:
- a non-transitory computer readable medium containing instructions that are executed by at least one processor configured to:
- receive, from a sensor associated with a vehicle configured to paint a lane line, a color attribute, a pattern attribute, and a location of the lane line painted on a road by the vehicle;
- determine using the location received, whether the road has an existing lane line;
- revise, in real time, a high-definition digital map associated with at least one autonomous vehicle by removing the existing lane line from the high-definition digital map and inserting the lane line in the high-definition digital map at the time of line painting to enable real-time updates to the high-definition digital map;
- and
- transmit, by the at least one processor, instructions to an autonomy computing system of an autonomous vehicle to change to a revised high-definition digital map, wherein the autonomy computing system is configured to control operation of the autonomous vehicle to navigate according to the revised high-definition digital map.
A method comprising:
- monitoring, in real-time, by at least one processor from a sensor, a color value, a pattern attribute, and a location of a lane line painted on a road by a vehicle at the time of line painting;
- transmitting, by the at least one processor, the color value, the pattern attribute, and the location of the lane line to a second processor, whereby the at least one processor revises, in real-time, a high-definition digital map based on received data from the sensor at the time of line painting to enable real-time updates to the high-definition digital map;
- and
- transmitting, by the at least one processor, instructions to an autonomy computing system of an autonomous vehicle to change to a revised high-definition digital map, wherein the autonomy computing system is configured to control operation of the autonomous vehicle to navigate according to the revised high-definition digital map.
