Recent developments of video cameras and frame grabber technology have led photogrammetrists into the fields of digital image processing and machine vision. This paper describes the components of a digital photogrammetric system for close range applications. The approach to image matching involves the location of preliminary matched details based on features which are used as initial approximations to determination of precisely matched areas on the two images. Image matching based on grey scale values uses the least squares matching method. A software package has been developed to determine object geometry from overlapping digital images, and results from test are presented for three combinations of base/height ratio. Future developments will be based on the use of a knowledge base to control the searching for matched points.
