Abstract:
1. A sensor system for analyzing a feature in a contiguous sensing volume, the sensor system comprising: a mounting structure; a first laser source being attached to the mounting structure and configured to project a pattern into the sensing volume and onto the feature forming a laser stripe on the feature; a first sensor being attached to the mounting structure and configured to image the laser stripe where the laser line intersects with the feature, a relationship between the first sensor and the first laser source having been precalibrated; a second sensor being attached to the mounting structure and configured to image the laser stripe where the laser line intersects with the feature, a relationship between the second sensor and the first laser source having been precalibrated; wherein the first sensor having a field of view that intersects with the pattern projected from the first laser source forming a first sensing volume, the second sensor having a field of view that intersects with the pattern projected from the first laser source forming a second sensing volume, the contiguous sensing volume being formed by the first and second sensing volume, wherein an encoded portion of the pattern is visible in both the first and second sensing volumes and wherein most of the first and second sensing volumes are not overlapping.
