Abstract

Camcorders offer several advantages over standard CCD-cameras. They are easy to use, transportable, provide a large integrated storage capacity and are inexpensive. This makes them ideal image acquisition devices for many tasks in Digital Photogrammetry. They were not designed for image metrology. Their geometric accuracy performance is potentially degraded by a number of factors. This paper gives a qualitative analysis of degrading effects from camera (color sensor and electronics) and video tape recording. Furthermore playback on another VCR, copying, and multiple playback are addressed. The investigation of their geometric and radiometric characteristics showed large response non-uniformities and degradations of the linearity. Geometric deformations were found to depend on the recording/playback configuration and shear components exceeding 1 pixel were detected. The warm-up-time was similar to that of standard CCD-cameras. The geometric accuracy performance was evaluated with a three-dimensional testfield. The color sensor and electronics reduced the accuracy by a factor of 2.8 and the intermediate storage on video tape introduced an additional performance degradation by a factor of 1.4. Accuracies with direct digitization and intermediate storage were 1/25^th and 1/20^th of the pixel spacing respectively. The corresponding relative accuracies in object space were 1/17.000 and 1/20.000.
