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 ensuring precision in medical treatment of a patient comprising one or more clusters of targets attached to a patient, a strapping mechanism or a carrier defining a patient-fixed coordinate system. The system also includes a first electro-optical measurement system for observing the one or more clusters of targets and local reference markers of an imaging system to determine the relationship between the patient-fixed coordinate system and a coordinate system of the imaging system, whereby a location to be treated inside the patient can be calculated in the patient-fixed coordinate system. The system further includes a second electro-optical measurement system for observing the one or more clusters of targets and local reference markers of a treatment system, whereby the location to be treated inside the patient can be calculated in a coordinate system of a treatment system.

Abstract: The invention relates to a system for determining spatial coordinates of points, wherein the system involves a fixed array of a network (2) of control points (3), and a manually or mechanically manipulatable measuring probe (1; 1′) containing at least one camera (9′, 9″, 9′″), and wherein the measuring probe (1; 1′) is designed for physical contact with a measuring point on an object (4) which is to be measured via a fixedly mounted contact unit (14) projecting from the measuring probe, which has a known, defined position in the coordinate system of the measuring probe; and a system unit (5) which computes the position of the contact unit (14) relative to a coordinate system defined by said control points (3) on the basis of the measuring probe's (1; 1′) image of the control points (3), and the known position of the contact unit (14) in the coordinate system of the measuring probe (1; 1′).

Abstract: A method and system for determining the position and/or orientation of a number of objects relative to each other. At least two cameras having electro-optical sensors are provided. A network of help reference points is established. The positions of some points in the network relative to each other can be known or they are determined using at least one of the cameras positioned in multiple arbitrary locations. The positions of some of the objects relative to each other, are determined based on the determined positions of some of the points in the network. The position of at least one of the objects is determined by holding a probing tool in contact with a point on the object, and obtaining measurement data from the probing tool using at least two of the cameras.

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.
