Abstract

In this work, we present an intuitive and interactive tool to model high quality 3D architectural objects starting from a MVS point cloud. Our implementation is inspired by [1] that describes the modeling system as well as the 3D reconstruction algorithm we use with some modification. We provide: • a simple mechanism to extract floor plans and profiles from a point cloud • an error computation between the modeled object and the point cloud • an easy way of using the pictures used to generate the MVS point cloud to improve the modeling An algorithm to merge two general events by automatically adjusting the profiles is also presented and finally, we show a texturing algorithm using the previously mentioned pictures.

Modeling language

A modeling language is any artificial language that can be used to express data, information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure Programing language. A modeling language can be graphical or textual. Graphical modeling languages use a diagram technique with named symbols that represent concepts and lines that connect the symbols and represent relationships and various other graphical notation to represent constraints.

Object-modeling technique

The object-modeling technique (OMT) is an object modeling approach for software modeling and designing. It was developed around 1991 by Rumbaugh, Blaha, Premerlani, Eddy and Lorensen as a method to develop object-oriented systems and to support object-oriented programming. OMT describes object model or static structure of the system. OMT was developed as an approach to software development. The purposes of modeling according to Rumbaugh are: testing physical entities before building them (simulation), communication with customers, visualization (alternative presentation of information), and reduction of complexity.

Systems modeling

Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. A common type of systems modeling is function modeling, with specific techniques such as the Functional Flow Block Diagram and IDEF0. These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition.
