Systems and methods for pose development using retrieved position of a pallet or product load to be picked up
First Claim
1. A method of operating an industrial vehicle comprising an environmental sensor array mounted to the industrial vehicle, a lift carriage comprising one or more lifting elements, a landmark sensor mounted to the lift carriage, and a mobile computer, wherein the method comprises using the mobile computer in combination with the environmental sensor array, the landmark sensor, or a combination thereof, for:
- determining a current pose of the industrial vehicle in an environment based on measurement data from the environmental sensor array;
navigating the industrial vehicle to a pallet or product load at a target destination utilizing the determined current pose of the industrial vehicle and data from the environmental sensor array;
executing a load engagement operation such that the one or more lifting elements are positioned to pick-up the pallet or product load at the target destination, and such that the landmark sensor is positioned to sense unique feature information identifying the pallet or product load at the target destination;
identifying unique pre-positioned object data associated with the pallet or product load at the target destination utilizing the landmark sensor when (i) the industrial vehicle is at the target destination, (ii) the load engagement operation is executed, and (iii) the unique feature information of the pallet or product load is sensed by the landmark sensor;
developing a new pose of the industrial vehicle using the unique pre-positioned object data associated with the pallet or product load at the target destination; and
navigating the industrial vehicle through the environment utilizing the new pose and data from the environmental sensor array of the industrial vehicle.

Abstract
A method and apparatus for using unique landmarks to position industrial vehicles during start-up. In one embodiment, a method of using pre-positioned objects as landmarks to operate an industrial vehicle is provided. The method comprises identifying a start-up scenario from sensor data, wherein the start-up scenario comprises a unique marker start-up or a pre-positioned object start-up. in response to the identified start-up scenario, either a unique marker or pre-positioned object is identified within a physical environment, wherein the pre-positioned object or unique marker corresponds with a sub-area of the physical environment. The industrial vehicle pose is determined in response to the identity of the pre-positioned object or unique marker and the industrial vehicle is operated based on the determined industrial vehicle pose.
