Title: Machine with movable legs for support and propulsion
Inventor: ZAMAGNI GIANCARLO
IPC: B62D57/032
Filed: 1995-11-06
Abstract: The machine frame is supported on the ground by three legs each side. Each leg has a jointed construction and is pivot mounted about a vertical axis (13) on the side of the machine, with a vertically adjustable support (7) to lift and lower the leg. A sliding support joint (8) under each leg provides the forward and backwards movement. The machine is propelled by lifting three legs and swinging them forwards while the remaining legs swing rearwards while supporting the machine. The sliding support joints (8) have a spherical support with a sliding mounting and are driven by a cranked drive (32) to swing the legs forwards and rearwards. The free ends of the legs have ground support pads. The machine is able to negotiate rough terrain and move over obstacles.

Filed: 1996-06-25
Abstract: In a system for measuring the geometry of large objects such a sheets of metal using a plurality of cameras each viewing only a part of the object, the cameras are calibrated so that the relationship between the image fields of the cameras can be determined. To calibrate the cameras, a calibration pattern 33 that is considerably smaller than the large object is accurately positioned in the field of view of each of the cameras in turn using a positioning device 30. The calibration pattern 33 comprises at least one geometric element 34, each geometric element including at least one characteristic point (37, fig 5). The calibration step involves selecting and or moving the calibration pattern so that at least three characteristic points are captured in the object field of each camera. The co-ordinates of the characteristic points of the geometric elements 34 are then transformed into the co-ordinate system of the positioning device 30.
