A high-resolution mobile handheld scanning device suitable for 3D data acquisition and analysis for forensic investigations, rapid prototyping, design, quality management, and archaeology with a measurement volume of approximately 325 mm x 200 mm x 100mm and a lateral object resolution of 170 µm developed at our institute is introduced. The scanners weight is 4.4 kg with an optional color DLSR camera. The PC for measurement control and point calculation is included inside the housing. Power supply is realized by rechargeable batteries. Possible operation time is between 30 and 60 minutes. The object distance is between 400 and 500 mm, and the scan time for one 3D shot may vary between 0.1 and 0.5 seconds. The complete 3D result is obtained a few seconds after starting the scan. For higher quality 3D and color images the scanner is attachable to tripod use. Measurement objects larger than the measurement volume must be acquired partly. The different resulting datasets are merged using a suitable software module. The scanner has been successfully used in various applications.
