The digital camera has lots of advantages,such as small size,light weight,inexpesive,high precision of pixel position,and available to be imported into computers etc, so it becomes more and more popular. With the development of digital photogrammetry and the increase of resolution of digital cameras, the feasibility of putting general camera to engineering use is considered. Based on images by general digital camera,the number, distribution and presicion of control points, the digital image acquirement and measurement, the data procesing methods and the presicion of calculation etc. are emphasized in this paper.
