The development of the construction world in terms innovation has become one methods supporting success to gain advantages cost and time, which is outer wall can generally categorize into cast-in-situ precast methods. (1) Comparison implementing kumkang materials, concrete facades, curtain facades. method 24% cheaper than method, 87% 52% method. Sorted from cheapest most expensive are facades.&...

The parsing of building facades is a key component to the problem of 3D street scenes reconstruction, which is long desired in computer vision. In this paper, we propose a deep learning based method for segmenting a facade into semantic categories. Man-made structures often present the characteristic of symmetry. Based on this observation, we propose a symmetric regularizer for training the neu...

We describe the prototype of a system intended to allow a user to navigate in an urban environment using a mobile telephone equipped with a camera. The system uses a database of views of building facades to determine the pose of a query view provided by the user. Our method is based on a novel wide-baseline matching algorithm that can identify corresponding building facades in two views despite...

ABSTRACT A methodology for the metric reconstruction of the planar surface of facades of destroyed buildings using historical single-view photographs has been presented in this work. The methodology is based on using a-priori object properties like linearity, parallelism, perpendicularity, symmetry etc. in addition to information extracted from the photographs. The methodology involves the dete...

There is an increasing interest of the scientific community in the generation of 3D facade models from terrestrial laser scanner (TLS) data. The segmentation of building facades is one of the essential tasks to be carried out in a 3D modelling process. Since in reality, majority of facade components are planar, the detection and segmentation of geometric elements like planes respond to the prev...

In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. We call this grammar F-shade. Our second contribution is a prototype rendering system that renders an urban model from the compact representation directly on the GPU. Our sugge...

The tilted viewing nature of the off-nadir aerial images brings severe challenges to building change detection (BCD) problem: mismatch nearby buildings and semantic ambiguity facades. To tackle these challenges, we present a multi-task guided network model, named as MTGCD-Net. proposed model approaches specific BCD problem by designing three auxiliary tasks, including: (1) pixel-wise classifica...

We introduce a novel approach for separating and segmenting individual facades from streetside images. Our algorithm incorporates prior knowledge about arbitrarily shaped repetitive regions which are detected using intensity profile descriptors and a voting–based matcher. In the experiments we compare our approach to extended state–of–the–art matching approaches using more than 600 challenging ...
