Therefore, the proposed system can allow our administrative staff to use the omnidirectional imaging system and model the indoor environment and our visually impaired users to navigate the same environment more efficiently and effectively.įigure 12-25. Also, we can generate turn-by-turn navigation guidance from A to B, even though the user-either a VIP or environment modeling staff-has never been to this building before. In summary, given any building available with AutoCAD documentations, we can detect the traversability between any two entities A and B (e.g. We compare the three paths and they also match correctly. We then compute the navigation summary, using the Dijkstra algorithm from the topological map, and the turn-by-turn directions, using the A ⁎ algorithm from the 3D traversable map. To test the performance of the topological and the 3D traversable maps, each time we randomly select two entities from the AutoCAD map and we manually calculate the shortest path between two entities. For the 3D traversable map, we project it into a 2D space and it aligns with the original AutoCAD map correctly as expected. We derive a topological map from the AutoCAD map and compare it with the one generated by our proposed algorithm, and they match correctly. For the topological map, we compare it with the original AutoCAD map. We manually verify the accuracy of the topological and the traversable maps. The rendered 3D traversable map for the input AutoCAD map in Fig. Then in the localization stage, when the user follows a path very similar to the path that has been planned by the model, the image-based localization would be much more effective.įigure 1.7. the entrance and a restroom, is calculated, single-path or multi-path based omnidirectional imaging modeling can be performed to provide a robust indoor localization service. Once the traversability between any two places, e.g. Using the same path planning algorithm for both environment modeling and pre-journey planning also makes the modeling and localization stages more consistent. They are widely used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince the clients of the merits of a design, or to make a record of a completed construction project. AutoCAD 14) and is available for buildings constructed in the past three decades.
#ARCHITECT DRAWING SOFTWARE#
An architectural drawing is a technical drawing of a building, usually using Computer Aided Design (CAD) software (e.g. In this section, we present the use of architectural drawings to achieve automatic path planning for both pre-journey planning by VIPs and environment modeling by developers. Zhigang Zhu, in Computer Vision for Assistive Healthcare, 2018 1.4.2.1 Map Parsing and Path Planning Beam elevations and column elevations are also given.īuilding grid lines, beams, and column schedule are shown below.įeng Hu. Steel design drawings: Design drawings tell the erector what beams and columns need to be used. Since two parties are involved, any issues that arise due to bad connection design are the responsibility of both the fabricator and the design engineer. But as per law, this would not release the design engineer from the responsibility. In many instances, a design engineer will delegate the design of connections to a steel fabricating shop. On the other hand, if welded in the field, workers can make minor adjustments to the piece so that it fits into the structure. Some of these issues include: What is the best method to attach a gusset plate to a beam? Should the plate be welded in the field or in the shop? Welding a steel member in a shop is always cheaper than welding in the field. During the shop drawings stage many issues that were not considered during the design phase will be considered. Steel fabricator use the design drawings and develop shop drawings. The contractor who won the contract will provide the design drawings to a steel fabricator. In addition, they provide the size of anchor bolts and various other structural information.ĭesign drawings and specifications are part of the contract. Structural engineers size up the columns and beams and provide the type of sections needed at each location. Once an architect has completed the architectural drawings, structural engineers design the columns and beams.
