Abstract:
Sensors used for 3D-reconstruction determine both the quality of the results and the nature of reconstruction
algorithms. The spectrum of such sensors ranges from expensive to low cost, from highly specialized to out-of-
the-shelf, and from stereo to mono sensors. The list of available sensors has been growing steadily and
is becoming difficult to manage, even in the consumer sector. We provide a survey of existing consumer 3D
sensors and a taxonomy for their assessment. This taxonomy provides information about recent developments,
application domains and functional criteria. The focus of this survey is on low cost 3D sensors at an accessible
price. Prototypes developed in academia are also very interesting, but the price of such sensors can not easily
be estimated. We try to provide an unbiased basis for decision-making for specific 3D sensors.
In addition to the assessment of existing technologies, we provide a list of preferable features for 3D reconstruction
sensors. We close wit
h a discussion of common problems in available sensor systems and discuss
common fields of application, as well as areas which could benefit from the application of such sensors.
