摘要： A sensor system for analyzing a feature in a sensing volume. The sensor system includes a laser source and a sensor. The first laser source projects a laser line into the sensing volume and onto the feature forming a laser stripe on the feature. The sensor images the laser stripe where the laser line intersects with the feature. The relationship between the sensor and the first laser source is precalibrated. The sensor uses the laser stripe to determine the position and/or orientation of the feature.

摘要： A structured light sensor system for measuring contour of a surface includes a control module that coordinates control of both a projection system and an imaging system to operate the structured light sensor system in three different modes. The imaging system is configured to selectively capture an image of light reflected off of the surface. In point mode, the imaging system is on for a first period during which the projection system projects a point of light onto the surface. In line mode, the imaging system is on for a second period during which the projection system projects onto the surface a first plurality of points of light forming a line of light. In area mode, the imaging system is on for a third period during which the projection system projects onto the surface a second plurality of points of light forming a plurality of lines of light.

摘要： A structured light sensor system for measuring contour of a surface includes an imaging lens system, an image capturing device, a first set of micro electromechanical system (MEMS) mirrors, and a control module. The imaging lens system focuses light reflected from the surface, wherein the imaging lens system has a corresponding lens plane. The image capturing device captures the focused light and generates data corresponding to the captured light, wherein the image capturing device has a corresponding image plane that is not parallel to the lens plane. The first set of MEMS mirrors direct the focused light to the image capturing device. The control module receives the data, determines a quality of focus of the captured light based on the received data, and controls the first set of MEMS mirrors based on the quality of focus to maintain a Scheimpflug tilt condition between the lens plane and the image plane.
