Large depth-of-view portable three-dimensional laser scanner and its segmental calibration for robot vision

The Workflows of 3D Digitizing Heritage Monuments

“…These features (for example, points, lines or components) will be extracted from images, enhancing the spatial characteristics and representing the coherence of geometry with mesh or solid of computer graphics algorithm (Datta, 2001;Li et al, 2007). The proposed feature extractors are adapted to solution software that includes CATIA and Rapidform XOR2 (Fig.…”

“…In application of manufacturing industry, inspection probes and survey are substituted by non-contact laser scanning equipment that are often used for aero industry and automotive parts design and testing (Willis et al, 2007). And more computer aided design and reverse engineering are employed in a wide range of applications in the field of science and industry, together with animation techniques and WEB application (Fontana et al, 2002;Li et al, 2007;Pieraccini, 2001). …”

“…Traditional tools using survey and probing in manuals couldn't correspond to preservation procedure in effective and efficient (Fontana et al, 2002;Li et al, 2007). It is necessary to consider an integrating mechanism with tools and procedures.…”

Review of Calibration Methods for Scheimpflug Camera

“…The Scheimpflug camera, adopting the Scheimpflug condition by tilting the lens with respect to the sensor [1,2], can optimize the distribution of depth of field (DOF) without zooming the aperture, which has been widely used in the field of PIV [3][4][5], line structured light [6], and portable 3D laser scanner [7,8]. At the same time, it has also been introduced into the medical field, greatly facilitating cataract and other ophthalmic surgery [9,10].…”

“…At the same time, it has also been introduced into the medical field, greatly facilitating cataract and other ophthalmic surgery [9,10]. So far, more and more scholars have also devoted themselves to the related research [6,7,[11][12][13][14][15][16][17][18].…”
