In order to promote the construction of digital geo-spatial framework in China and accelerate the construction of informatization mapping system, three-dimensional geographic information model emerged...
Computer tomography (CT) is an excellent technique for obtaining accurate 3D information about the human body. It allows to visualize the organs, bones and blood vessels, furthermore it enables to dia...
In this work, it is examined the 2D recognition and 3D modelling of concrete tunnel cracks, through visual cues. At the time being, the structural integrity inspection of large-scale infrastructures i...
This study aims at building a robust semi-automated pavement marking extraction workflow based on the use of mobile LiDAR point clouds. The proposed workflow consists of three components: preprocessin...
Conventional building inspection of bridges, dams or large constructions in general is rather time consuming and often cost expensive due to traffic closures and the need of special heavy vehicles suc...
Quality Inspection and Quality Improvement by Map Fusion     Data Fusion  Matching  Quality Inspection       font style='font-size:12px;'> 2015/12/2
In this paper a new approach for quality measurement and improvement using map matching and map fusion is introduced. In the first part we describe a matching model based on “Buffer growing”. The matc...
Infrastructure asset management is a framework for achieving sustainable infrastructure. Based on this framework, although we often generate a three-dimensional (3D) geometrical model as a base map in...
UAVs equipped with high-resolution thermal cameras provide an excellent investigative tool used for a multitude of building-specific applications, including roof insulation inspection. We have present...
This paper introduces a compact LIDAR system designed to inspect overhead transmission line for maintenance purposes. This LIDAR system is carried by a small unmanned helium airship, which is guided b...
Aerial photography has a long history of being employed for mapping purposes due to some of its main advantages, including large area imaging from above and minimization of field work. Since few years...
Close-range photogrammetric measurement systems are increasingly used for high-precision surface inspection of car body parts. These measurement systems are based on an active light source, the projec...
For Chinese paper charts, no standards are made yet, quality of paper charts are controlled by “there-level inspection” with naked eyes at present. This method has many disadvantages like more error...
