Abstract: A system for precision guidance of surgical procedures on a patient is disclosed. Aspects of the system may include: a three-dimensional digital representation of a pre-procedural geometry of a relevant part of the patient, a three-dimensional digital representation of an intended post-procedural geometry of the relevant part of the patient including any implant or other structures intended to be attached to the patient, and a movable electro-optical (EO) camera mounted in a known position and orientation relative to a surgeon, such as a head mount.

Abstract: A weapon platform for accurately locating and/or tracking enemy targets is described. The weapon platform may include an electro-optical sensor unit comprising one or more sensors, an electro-optical camera, and a plurality of local targets located within the weapon system. The camera may observe the local targets and output information regarding the spatial relationship between the sensor unit and a weapon connected to the weapon platform. The local targets may be connected to the weapon, to the weapon platform, and/or to the sensor unit. Using the information regarding the spatial relationship, the weapon may be steered toward enemy targets that are located using the sensor unit.

Abstract: A system for measurement of spatial coordinates comprising a probing tool and a main measuring unit, wherein said probing tool comprises a reflective object element, observation mechanism located in a known position and orientation relative to said reflective object element and capable of observing targets; and wherein said main measuring unit comprises a distance measuring device capable of measuring a distance from said device to said reflective object element; a mechanism constructed and adapted to direct a measuring beam from said distance measuring device to said reflective object element; a direction determining mechanism constructed and adapted to determine a direction of a measuring beam; at least two targets located in known positions relative to said distance measuring device, whereby the orientation of said reflective object element can be determined from observations of said targets by said observation mechanism.

Abstract: Method and system for determination of relative position and/or orientation of a number of points or geometrical objects like planes, lines, holes, cylinders or spheres, or combined objects like robot arms or other industrial production equipment, based on the use of one or more cameras based on electro-optical sensors, in combination with permanently mounted light sources, projected light spots,illuminated reflectors, or probing tools having light sources or reflectors attached thereto. The camera (1) is arranged to measure the projection of light spots on the cameras sensor (4) in a number of camera locations, and measurements are made such that each light source or light reflection (18; 14; 15; 16) is observed from two or more camera locations (1; 8), by the observations being registered as image coordinates relates to a camera fixed coordinate system.

Abstract: A system for point by point measurement of spatial coordinates, in which a touch probe including three point-sized light sources at known local coordinates relative to a local probe fixed coordinate system and with a touch point at known location relative to the local coordinate system, is used such that the touch probe touches the point to be measured. A single opto-electronic angle sensor for measurement of spatial direction towards point sized light sources is set up such that its field of view/work area covers the essential parts of the object to be measured, and such that the light sources of the touch probe are seen from the angle sensor for all the relevant measurement points. The spatial directions for all of the light sources of the touch probe are registered simultaneously.
