The authors of the article eliminated this drawback by using two non-orthogonally located cameras, the focuses of which coincide with the location of the crystal on the working tool. The resulting two images are then processed. The contours of the reference marks on the substrate, already installed elements and the mounted crystal are highlighted. After geometric transformations of the selected contours, the operator receives a real-time map of elements and can adjust the position of the chip in the horizontal plane. All operations are performed in real time. This approach has been practically tested on industrial equipment developed with the direct participation of the authors. |
