Abstract
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.
