Abstract
Rewind processing of aerial films will continue, at least on overseas survey operations, until a similarly portable alternative is available. This paper reports a series of practical tests which compare the method with the use of a continuous film processing machine. Comparisons are also made with an earlier report on the same subject. Variations obtained along the length and across the width of 240 mm wide film are given. Whilst indicating the methods for obtaining optimum results, the shortcomings of the rewind method are acknowledged.
Resume
On continuera a developper les films par la methode traditionnelle, au moins pour les leves outre-mer, tant qu on ne pourra utiliser des methodes plus modernes au moins aussi commodes. On analyse ici des tests de comparaison avec la methode ou on utilise une machine a developpement continu, et on complete un rapport recent sur le meme probleme. On donne les erreurs a craindre dans le sens longitudinal et transversal (largeur 240 mm). On decrit toutes les insuffisances de la methode classique, tout en donnant des indications sur la meilleure facon de l'utiliser.
Zusammenfassung
Die Umspul-Entwicklung von Luftbildfilmen wird weiter angewendet werden, zumindest bei Arbeiten in Ubersee, Solange nicht eine transportable Alternative existiert. Im vorliegenden Artikel wird eine Reihe praktischer Tests beschrieben, bei der die Umspulentwicklung mit der Verarbeitung in einer kontinuierlichen Durchlauf-Entwicklungsmaschine verglichen wird. Es Werden auch Vergleiche zu einem fruheren Bericht uber den gleichen Gegenstand gezogen. Die Fehler in Filmrichtung und quer dazu bei einer Breite von 240 mm werden angegeben. Wahrend die Verfahren zur Erlangung optimaler Ergebnisse aufgezeigt werden, werden gleichzeitig die Unzulanglich-keiten der Umspulverfahren anerkannt.
期刊介绍:
The Photogrammetric Record is an international journal containing original, independently and rapidly refereed articles that reflect modern advancements in photogrammetry, 3D imaging, computer vision, and other related non-contact fields. All aspects of the measurement workflow are relevant, from sensor characterisation and modelling, data acquisition, processing algorithms and product generation, to novel applications. The journal provides a record of new research which will contribute both to the advancement of photogrammetric knowledge and to the application of techniques in novel ways. It also seeks to stimulate debate though correspondence, and carries reviews of recent literature from the wider geomatics discipline.
Relevant topics include, but are not restricted to:
- Photogrammetric sensor calibration and characterisation
- Laser scanning (lidar)
- Image and 3D sensor technology (e.g. range cameras, natural user interface systems)
- Photogrammetric aspects of image processing (e.g. radiometric methods, feature extraction, image matching and scene classification)
- Mobile mapping and unmanned vehicular systems (UVS; UAVs)
- Registration and orientation
- Data fusion and integration of 3D and 2D datasets
- Point cloud processing
- 3D modelling and reconstruction
- Algorithms and novel software
- Visualisation and virtual reality
- Terrain/object modelling and photogrammetric product generation
- Geometric sensor models
- Databases and structures for imaging and 3D modelling
- Standards and best practice for data acquisition and storage
- Change detection and monitoring, and sequence analysis
