This paper describes recent research concerning the Active Stereo Probe (ASP) stereo vision system that combines animate oculo-motor reflexes with a novel active illumination source. Two methods for accurate surface recovery from stereo at rates approaching real time are described. Results using texture projection combined with a fast sub-pixel matching algorithm are presented. The development ...

This paper focuses on the use of control linear features extraction from a terrestrial laser scanning (TLS) surface to produce a good datum definition for a close range photogrammetric model. The difficulty of identifying conjugate points between both datasets is overcome by the derivation of automatic features extraction. Hence, the extracted features from the terrestrial measurements represen...

The use of non-metric digital cameras in close-range photogrammetric applications and machine vision has become a popular research agenda. Being an essential component of photogrammetric evaluation, camera calibration is a crucial stage for non-metric cameras. Therefore, accurate camera calibration and orientation procedures have become prerequisites for the extraction of precise and reliable 3...

Unmanned aerial vehicles (UAVs) and digital photogrammetric techniques are two recent advances in remote sensing (RS) technology that are emerging as alternatives to high-cost airborne laser scanning (ALS) data sources. Despite the potential of UAVs in forestry applications, very few studies have included detailed analyses of UAV photogrammetric products at larger scales or over a range of fore...

UAVs are becoming standard platforms for photogrammetric data capture especially while aiming at large scale aerial mapping for areas of limited extent. Such applications especially benefit from the very reasonable price of a small light UAS including control system and standard consumer grade digital camera, which is some orders of magnitude lower compared to digital photogrammetric systems. W...

UAV platforms are nowadays a valuable source of data for inspection, surveillance, mapping and 3D modeling issues. New applications in the shortand close-range domain are introduced, being the UAVs a low-cost alternatives to the classical manned aerial photogrammetry. Rotary or fixed wing UAVs, capable of performing the photogrammetric data acquisition with amateur or SLR digital cameras, can f...

Traditional photogrammetric method has been a system for documentation, 3D modelling for long years. After the development of digital photogrammetrical systems, map products can be monitored in CAD platforms. Placing models in CAD had verified flexibility for getting information from model and easy editing for modelling. Terrestrial Laser Scanning Systems provide modelling of objects without sc...

Nowadays lidar and photogrammetric surveys have been used together in many mapping procedures due to their complementary characteristics. Lidar survey is capable to promptly acquire reliable elevation information that is sometimes difficult via photogrammetric procedure. On the other hand, photogrammetric survey is easily able to get semantic information of the objects. Accessibility, availabil...

Photogrammetry offers suitable, reliable and accurate methods for gathering data and making 3D digital models, which have vast applications in design and implementation of information systems such as GIS. On the other hand, Computer Aided Design (CAD) systems are used for drawing, editing, and representing 3D geometric models of features. CAD editing functions are used for simplifying data-clea...
