| Abstract: | With the development of electronic technology the non-measure camera becomes the main device for detecting the digital close-range photogrammetry because of the changeable lens, flexible operation, convenience and low price. There are problems of low accuracy and efficiency in engineering application of detection of close-range photogrammetry.： In order to solve the problems an algorithm based on Harris feature point extraction is proposed in the paper. |
