Abstract
A portable dimensional reference (PDR) that is transportable to a tower site and deployable on site at ground level near a tower. The PDR includes a pair of target pads and multiple connecting segments, which may be attached end-to-end between the target pads. The target pads are marked with respective targets that enable photogrammetry software to identify the targets, their locations, and the distance between them with high precision, enabling the software to apply the known distance as a scale constraint for accurately scaling dimensions of imaged components of the tower.
Claims5
A method of using one or more portable dimensional references (PDRs), the method comprising:
- transporting a carrying bag to a location of a tower, the carrying bag including components of a PDR, the components including a first target pad having a first target formed thereon, a second target pad having a second target formed thereon, and a set of multiple connecting segments configured to connect end-to-end between the first target pad and the second target pad to establish a known distance between the first target and the second target;
- removing the components of the PDR from the carrying bag at the location of the tower;
- assembling the PDR at least in part by attaching the connecting segments of the set of connecting segments end-to-end between the first target pad and the second target pad at a location within a predetermined distance from the tower;
- and
- performing photogrammetric measurements on the tower based at least in part on the known distance established by the PDR.
