In last years, ROVs, have been employed to explore underwater environments and have played an important role for documentation and surveys in different fields of scientific application. In 2017, the L...
This paper studies self-calibration of a structured light system, which reconstructs 3D information using video from a static consumer camera and a handheld cross line laser projector. Intersections b...
In-situ calibration of structured light scanners in underwater environments is time-consuming and complicated. This paper presents a self-calibrating line laser scanning system, which enables the crea...
With the increasing acceleration of urbanization, the degeneration of the environment and the Urban Heat Island (UHI) has attracted more and more attention. Quantitative delineation of UHI has become ...
At present, the on-orbit calibration of the geometric parameters of a space surveying camera is usually processed by data from a ground calibration field after capturing the images. The entire process...
This paper proposes a new, integrated method for the self-calibration of 3D laser range cameras (LRCs) and corresponding systematic error models. Unlike other recently-proposed methods that consider ...
It is well known that vanishing point based analysis requires images with strong perspective effects due to wide angle lenses, close objects, and often oblique viewing angles. Aerial imagery, however...
Terrestrial laser scanners provide a three-dimensional sampled representation (i.e. point cloud) of the surfaces of objects. They have great potential to improve the measurement and representation of ...
Similar to other electronic instruments, terrestrial laser scanner (TLS) can also inherent with various systematic errors coming from different sources. Self-calibration technique is a method availabl...
Nowadays, Global Positioning System (GPS) receivers are aided by some complementary radio navigation systems and Inertial Navigation Systems (INS) to obtain more accuracy and robustness in land vehicu...
In the context of 3D building model production or updating, the models have to be manually checked one by one by a human operator in order to ensure their quality. In this paper, we investigate a new ...

Linear array CCD-based panoramic cameras have a high potential for measurement applications due to their design in acquiring 360 degree field of views and high information content with up to a Giga-pi...
Commercially available high-resolution satellite imagery from sensors such as IKONOS and QuickBird are important data sources for a variety of urban area applications including infrastructure feature ...
This article consists to explain the application of a semi automatic and multi temporal method of classification of the spot images.The objective is to follow the evolution of the units of landscapes ...
