Vision Based Blade Positioning

Precise knowledge of the pose or position of the implement with respect to the body of a piece of construction equipment is fundamental to the ability to perform precision grading and excavation tasks.  This information is typically gathered using a collection of sensors and associated cabling mounted on the implement and/or across the joints of the articulation.

This concept originated when I realized that the geometry of host equipment could be used to provide the additional constraints required to construct a bijective projection of locations on the implement using images from a single camera mounted to the body of the equipment.  The use of a single camera rather than a stereo camera would greatly reduce the cost and complexity of a vision-based blade positioning implementation.
