Abstract:
1. A method for determining the dimensions of at least one item, the method comprising: determining an approximate location and extent of at least one item; acquiring a first set of point cloud data by utilizing a first laser to transmit a first signal over the at least one item and utilizing a first camera to receive a reflection of the first signal; utilizing a second laser and a second camera to determine an approximate location and a dimension of the at least one item; acquiring a second set of point cloud data by utilizing the second laser to transmit a second signal over the at least one item and utilizing the second camera to receive a reflection of the second signal; acquiring a third set of point cloud data by utilizing the second camera to receive the reflection of the first signal; constructing a three-dimensional image that defines the at least one item by merging the acquired first, second and third sets of point cloud data; and determining a rectangular prism having a height, length and breadth to contain the constructed image defining the at least one item to ascertain the rectangular prism within which the at least one item will fit.
