چکیده انگلیسی


- This paper proposes a point-based reconstruction method for boxes and polygonal prisms in engineering plants.
- Many faces may be partly occluded by other objects in engineering plants.
- In our method, possible shapes are estimated and they are verified using their compatibility with measured point-clouds.
- In our experiments, our method achieved high precision and recall rates.

The advent of high-performance terrestrial laser scanners has made it possible to capture dense point-clouds of engineering facilities. 3D shape acquisition from engineering facilities is useful for supporting maintenance and repair tasks. In this paper, we discuss methods to reconstruct box shapes and polygonal prisms from large-scale point-clouds. Since many faces may be partly occluded by other objects in engineering plants, we estimate possible box shapes and polygonal prisms and verify their compatibility with measured point-clouds. We evaluate our method using actual point-clouds of engineering plants.
