Abstract: A calibration system is provided for calibrating a sensor with respect to an external reference frame associated with manufacturing gauging station. A target calibration device is positioned at a vantage point to detect and calibrate its reference frame in relation to the external reference frame. A reference target having at least three non-coplanar reflective surfaces is illuminated by the structured light emanating from the sensor. In this way, the calibration system is able to determine the spatial location and orientation of the reference target in relation to the sensor. The calibration system further includes a coordinate transformation system for coordinating the measurement data from the target calibration device and from the feature sensor, whereby the feature sensor is calibrated with respect to the external reference frame.

Abstract: The photogrammetric measurement system is positioned at a vantage point to detect and calibrate its reference frame to the external reference frame demarcated by light-reflecting retroreflective target dot on a spherical target. A tetrahedron framework with the spherical target mounted on one of the vertices serves as a reference target that is placed in front of the non-contact sensor to be calibrated. The photogrammetric measurement system reads and calibrates the position of the retroreflective target dot (and thus the tetrahedron) while the structured light of the sensor is projected onto the framework of the reference target. The structured light intersects with and reflects from the reference target, providing the non-contact sensor with positional and orientation data. This data is correlated to map the coordinate system of the non-contact sensor to the coordinate system of the external reference frame.

Abstract: A temperature compensation system (300) is provided for compensating measurements from a sensor (240). A temperature transducer (310) is placed in close proximity to a manufacturing workstation as a means of measuring the ambient temperature associated with the workstation (200). A reference workpiece (100) is placed within a sensing zone of the sensor (240). The system (300) includes a temperature compensating module (320) that is connected to the sensor (240) and to the temperature transducer (310) for determining a baseline measurement of the reference workpiece at a reference temperature. The temperature compensating module (320) is further adapted for collecting a plurality of measurements of the reference workpiece over a plurality of temperatures for establishing a relationship between these measurements and their corresponding temperature values.

Abstract: The laser tracker is positioned at a vantage point to detect and calibrate its reference frame to the external reference frame demarcated by light-reflecting retro reflector. A tetrahedron framework with retro reflector mounted on one of the vertices serves as a reference target that is placed in front of the non-contact sensor to be calibrated. The laser tracker reads and calibrates the position of the retro reflector (and thus the tetrahedron) while the structured light of the non-contact sensor is projected onto the framework of the reference target. The structured light intersects with and reflects from the reference target, providing the non-contact sensor with positional and orientation data. These data are correlated to map the coordinate system of the non-contact sensor to the coordinate system of the external reference frame.

Abstract: The sensor array is positioned at a vantage point to detect and calibrate its reference frame to the external reference frame demarcated by light-emitting reference indicia. The sensor array encompasses a wide view calibration field and provides data indicating the spatial position of light sources placed within the calibration field. A tetrahedron framework with light-emitting diodes at the vertices serves as a portable reference target that is placed in front of the feature sensor to be calibrated. The sensor array reads and calibrates the position of the light-emitting diodes at the vertices while the structured light of the feature sensor is projected onto the framework of the reference target. The structured light intersects with and reflects from the reference target, providing the feature sensor with positional and orientation data. These data are correlated to map the coordinate system of the feature sensor to the coordinate system of the external reference frame.

Abstract: The non-contact sensor employs a structured light source that emits light in a predefined planar configuration and an optical receiver for reading reflected light produced by the structured light source within a predefined field of view. A tetrahedron target structure includes a three-dimensional framework that defines at least three non-collinear, non-coplanar structural lines each simultaneously visible to the sensor. A calibration system is coupled to the gauging system and the non-contact sensor for calibrating the gauging system by evaluating the geometric relationship of the structured light reflected from the structural lines of the target structure to determine the position and orientation of the target structure and then correlating the structural lines to the gauging system.

Abstract: One or more non-contacting gauging sensors are calibrated to a common external coordinate system by providing each sensor to be calibrated with a target which can be simultaneously viewed by the sensor and an external measuring system for determining coordinates of the target in terms of the external coordinate system and in terms of the sensor coordinate system. With the resulting spatial coordinates of the target expressed in both frames of reference, transform matrix coefficients can be calculated, for example with a programmable computer, to calibrate each sensor to the preselected common external coordinate system.
