[Termes IGN] photogrammétrie terrestreRésumé : (Auteur) Close range photogrammetry has proved effective as a cost-effective and easy-to-use method for cultural heritage recording. Off-the-shelf digital cameras can be used to rapidly acquire data at low cost, allowing non-experts to become more involved in their local heritage, an important aspiration identified in this collaboration between English Heritage and Loughborough University. To achieve this while also allowing for measurements in a 3D national reference system, a recording system has been developed that is capable of deriving the exterior orientation during exposure directly and cheaply. The system comprises a digital camera, a small 3D orientation sensor and a GNSS antenna, assembled in a frame that allows calibration of the offsets between the components. Test field data was used to investigate calibration precision and stability as well as achievable absolute and relative accuracy. The results of data analysis indicate that the system can meet the accuracy requirements for medium accuracy heritage recording, even with slightly unstable offset calibration values.

[Termes IGN] photographie terrestreRésumé : (Auteur) There are several approaches which can be adopted to present close-range photogrammetry in France: historical, eco-nomic, technical, or by field of application. The paper starts with a short account of the history of close-range photogram-metry. It then presents notable technical progress and its impact on users (the digital era, the laser scanners, and recently the fully automatic tools), and it finally shows the democratization of photogrammetry. The whole paper is mainly focused on cultural heritage applications.

OT image reconstruction requires that source optical fibres and detector bundles (optodes) are brought into optical contact with the head and that the scalp surface geometry and optode positions for each individual infant are accurately known. The photogrammetric challenge is to create affordable tools that can be employed on newborn, and often severely ill, infants in an intensive care environment with a minimum level of intrusion. The paper describes the application and development of a system capable of mapping each individual infant head surface in the clinic and coordinating optode positions and orientations during optical tomography scans. The system developed includes a combination of stereo and multi-photo photogrammetry with a pair of digital SLR cameras and a laser dot projector. A bundle adjustment of the sequential stereo-image pairs is used to generate accurate head meshes that are combined with a photogrammetric network of images from a single camera to bring optodes mounted on a deformable helmet structure into a common coordinate system. This data can then be used in the 3D reconstruction of blood flow in the infant head.

[Termes IGN] utilisateurRésumé : (Auteur) Lately, the cost of HD video camcorders has decreased greatly and the inclusion of an internal hard disk in many models has eased the bother of downloading video clips from cumbersome tape devices. These factors have increased their potential as 3D recording devices and measurement tools for the health monitoring of patients by practitioners. This investigation determined: (1) the 3D measurement quality of off-the-shelf high definition camcorders for human-movement-related medical applications; (2) the suitability of a low-cost LED synchronisation device for multi-camcorder tracking; and (3) the suitability of these imaging sensors for practitioners. The results show that a four-camcorder system is capable of measuring a 3D distance in a static setting to better than 0·050 mm; it can track a moving calibrated square-wave signal of 0·5 and 1 Hz to better than 0·3 and 0·2 mm, respectively. Using a calibrated scale bar mounted on a moving human leg, the error produced as a result of frame disparity using a low-cost LED frame-synchronising device was under 0·3 mm for a four-, three- and two-camcorder configuration.

[Termes IGN] surveillance d'ouvrageRésumé : (Auteur) Close-range photogrammetry has been used to control the construction of a jig used in the assembly of a new genera-tion solar concentrator and the validation of the final, mirrored surface. The concentrator is a concave paraboloid dish with an area of a 489 m2. The typical photogrammetric relative precision realized was 1:175,000, corresponding to an accuracy of better than 1 mm at the jig reference points. The validation of the mirrored surface achieved a relative precision of 1:300,000. Photogrammetry was also used to characterize the dish mirror panels. The rear surface of the panels was mapped, as it made possible a denser target array and quicker image capture than if the reflective surface was used. The targets were produced with a digital projector, and the typical measurement precision attained was 1:150,000. This paper describes the equipment and techniques required to provide the required accuracy and precision for the jig and panel surfaces.
