| 发明名称 | Machine positioning system having alignment error detection | ||
| 摘要 | A method and system for determining an alignment error between sensors mounted to a machine is disclosed. The method may include calculating a first orientation value based on a signal received from a first sensor. The method may further include calculating a second orientation value based on a signal received from a second sensor. The method may further include calculating an alignment error between the first sensor and the second sensor based on a difference between the first orientation value and the second orientation value. | ||

| 主权项 | 1. A method for determining an alignment error between sensors mounted to a machine, comprising: calculating a first orientation value based on a signal received from a first sensor; calculating a second orientation value based on a signal received from a second sensor; calculating the alignment error between the first sensor and the second sensor based on a difference between the first orientation value and the second orientation value, wherein the first sensor is a dual forward-aft GPS receiver and the second sensor is an inclinometer; and controlling and positioning the machine with an improved estimation of a pose of the machine based on the alignment error between the first sensor and the second sensor. | ||
