| A Study of the Accuracy Improvement Strategy for Multi-view 3D Reconstruction Instrument Based on Automatic Calibration Technology |
| To tackle the problem of low geometric accuracy of traditional Multi-view 3D Reconstruction (MV3DR) instrument, this paper proposed an accuracy improvement method by using automatic calibration technology, and applied this method to the MV3DR instrument developed by the authors. This method teckles the problem of expensive time cost in the traditional camera calibration processing, and achieves the high-accuracy calculation for exterior orientation elements of camera. Because of the automatic characteristics, this method can improve the 3D reconstruction accuracy of MV3DR with inexpensive time cost, and therefore has wide application prospect. |
