| titleOfInvention | Apparatus and method for making accurate three-dimensional size measurements of inaccessible objects |
| abstract | Spatial locations of individual points on an inaccessible object are determined by measuring two images acquired with one or more cameras which can be moved to a plurality of positions and orientations which are accurately determined relative to the instrument. Once points are located, distances are easily calculated. This new system offers accurate measurements with any convenient geometry, and with existing endoscopic apparatus. It also provides for the measurement of distances which cannot be contained within any single camera view. Systematic errors are minimized by use of a complete and robust set of calibration procedures. A standard measurement procedure automatically adjusts the measurement geometry to reduce random errors. A least squares calculation uses all of the image location and calibration data to derive the true three-dimensional positions of the selected object points. This calculation is taught explicitly for any camera geometry and motion. |
