METHOD, SYSTEM AND APPARATUS FOR DYNAMIC TARGET FEATURE MAPPING

Abstract:

A method for dynamic target feature mapping in a mobile automation apparatus includes, at a navigational controller of the apparatus: obtaining mapping trajectory data defining a trajectory traversing a facility to be mapped; controlling a locomotive mechanism of the apparatus to traverse the trajectory; generating a sequence of keyframes and corresponding estimated mobile automation apparatus poses in a facility frame of reference during traversal of the trajectory, using a navigational sensor of the mobile automation apparatus; simultaneously with generating a target-associated one of the keyframes, detecting a target feature using an environmental sensor of the mobile automation apparatus; storing a relative target location of the target feature, defined relative to the estimated pose of the target-associated keyframe; generating a map of the facility based on the sequence of keyframes; and storing a final target location for the target feature, defined in the facility frame of reference.
