Methods for commissioning a construction vehicle for machine control operations are provided. A GNSS receiver configured for determining position information, tilt information, and heading information is coupled to a rigid member of the construction vehicle. The commissioning process provides parameters that can be used for tracking and controlling movement of an implement coupled to the construction vehicle during the machine control operations.

Commissioning a construction vehicle for machine control

A system for tracking a position of a working edge on an implement of a construction vehicle includes a GNSS with an antenna. The GNSS unit is configured to determine a position of the antenna and a tilt and a heading of the GNSS unit. A mount is configured to couple the GNSS unit to a rigid member of the construction vehicle. The mount is configured to couple the GNSS unit to the rigid member so that the antenna is arranged in a known spatial relationship with a pivot point between the rigid member and the implement. A mobile controller is configured for wireless communications with the GNSS unit and an angle sensor that is configured to determine rotation of the implement. The mobile controller is configured to receive the position of the antenna, the tilt, and the heading from the GNSS unit, to receive the rotation of the implement from the angle sensor, and to determine coordinates of the working edge of the implement in a real world coordinate frame.

Tracking a position of a working edge on an implement of a construction vehicle

Various embodiments provide novel tools and techniques for photogrammetric machine measure-up, including without limitation solutions that can be used for excavation and similar applications. A system includes a machine, a user device may further comprise an image sensor, an accelerometer, a processor, and a computer readable medium in communication with the processor, the computer readable medium having encoded thereon a set of instructions executable by the processor to photogrammetrically measure-up the machine. Photogrammetric measure-up includes capturing, via the image sensor, two or more target images of each of the two or more targets, the two or more target images including a first target image and a second target image, and determining a measurement between two of the two or more reference features of the machine based on a first target image and second target image.
