Highspeed cameras form a central component of photogrammetric 3D measurement systems in applications requiring a
high temporal resolution in fields such as fast object tracking or high frequency deformation measurement. Current highspeed
cameras offer data rates in the order of 1 Gigabyte per second or beyond, delivering for instance 1000 frames per
second at 1000×1000 pixels. Most applications using highspeed cameras for visualization or measurement purposes are
still 2D. Highspeed camera stereo systems are rare because of the costs of cameras and the lack of synchronizibility of
some camera types.
The paper gives a short overview on single camera 3D measurement system concepts. It presents two concepts of setting
up photogrammetric 3D measurement systems based on a single highspeed camera in detail, one based on a single camera
with a stereo mirror system and one on based on a camera-projector combination:
A stereo mirror system in front of a camera generates multiple views on one sensor. These views can be considered
virtual cameras of a multi-camera photogrammetric measurement system. The paper presents a flexible quadruple-mirror
system to be used in 3D motion analysis applications and discusses geometric modeling and system calibration.
Photogrammetric surface measurement systems can be configured by a camera and a projector device projecting
strip or dot patterns onto a surface. Using the projector as an active element in the system design, dense and accurate
3D surface representations may be generated using coded light approach or phase shift techniques. In the geometric
modeling and calibration, the projector can be considered an inverse camera with infinite frame rate. The paper presents
results of an accuracy test obtaining a precision potential in the order of 1/50 pixel from a standard consumergrade
Besides the system design and the geometric modeling of the two concepts, the paper shows results from pilot studies
and practical applications.
