MACHINE POSITIONING SYSTEM UTILIZING POSITION ERROR CHECKING |
摘要 |
A system and method for estimating position of a machine is disclosed. The method may include receiving, from a perception sensor, scene data describing an environment in a vicinity of the machine and estimating a first position of the machine based on the scene data. The method may include determining whether a first signal indicative of a location of the machine is received by the machine and estimating a second position of the machine when it is determined that the first signal is received. The method may include comparing the second position with the first position and estimating a third position of the machine using at least one of the first position and the second position. |

1. A method of estimating position of a machine, comprising:
receiving, from a perception sensor, scene data describing an environment in a vicinity of the machine; estimating a first position of the machine based on the scene data; determining whether a first signal indicative of a location of the machine is received by the machine; estimating a second position of the machine when it is determined that the first signal is received; comparing the second position and the first position; and estimating a third position of the machine using at least one of the first position and the second position, wherein estimating the third position is performed based on a result of the comparison between the second position and the first position. |
