Abstract: A method and system for non-contact location and orientation determination for an implement coupled with a mobile machine. One example detects an orientation of a recognized feature of an implement with a sensor mounted at a fixed location on the mobile machine. A range from the sensor to the recognized feature of the implement is also determined. In addition, a known operating envelope of the implement coupled with the mobile machine is accessed. The known operating envelope of the implement is then combined with the orientation and the range from the sensor to determine a position of the implement with respect to the mobile machine.

Abstract: A method for performing point-to-point measurements includes (i) determining a distance to a first point and obtaining an image at a first pose, and (ii) determining a distance to a second point and obtaining an image at a second pose. The images have an overlapping portion. A change in pose between the first pose and the second pose is determined using observed changes between common features in the overlapping portion of the images and a scale associated with the images. A distance between the first point and the second point is determined based on the first distance, the second distance, and the change in pose between the first pose and the second pose.
