摘要：Photogrammetry is often considered one of the most precise and versatile surveying techniques. The same camera and analysis software can be used for measurements from sub-millimetre to kilometre scale. Such a measurement device is well suited for application by earth scientists working in the field. In this case a small toolset and a straight forward setup best fit the needs of the operator. While a digital camera is typically already part of the field equipment of an earth scientist, the main focus of the field work is often not surveying. Lack in photogrammetric training at the same time requires an easy to learn, straight forward surveying technique. A photogrammetric method was developed aimed primarily at earth scientists for taking accurate measurements in the field minimizing extra bulk and weight of the required equipment. The work included several challenges. a) Definition of an upright coordinate system without heavy and bulky tools like a total station or GNS-Sensor, b) optimization of image acquisition and geometric stability of the image block, c) identification of a small camera suitable for precise measurements in the field, d) optimization of the workflow from image acquisition to preparation of images for stereo measurements, e) introduction of students and non-photogrammetrists to the workflow
