A study acquiring for 3-dimension data by measurement method using digital camera and GPS

摘要

In this part of study we have got efficiency 3 dimensions data by using GPS and digital camera and we devised the measurement method. After this according to measurement method of one reference point we constructed one system and verify it. As for the condition of observation we took photograph from at least three low places and we established one reference point in the side of the survey object, also we requested and learned this coordinates by using GPS. The process of the analysis was, observation of the place from where we took photograph and set up the reference point, measured the image of the digital photograph, occurred the one by one digital photogrammetry, we requested the relation between survey object and digital photograph, and then by using method of space inquire area correlation we acquired automatic three dimension data.
