The traditional methods to obtain three-dimensional（ 3 D） data need a lot of extra hardware device

and are not suitable for 3 D reconstruction on large scenes outdoor. The method based on photogrammetry and image optical flow is proposed

it only needs a camera to obtain for 3 D data by shooting a series of pictures

and it can be used for 3 D data acquisition in outdoor scene. According to the method of close shot photogrammetry

it can obtain intrinsic and external parameters of the camera; and according to the optical flow method

it can get image points matching information and color information on two images

according to camera calibration data

matching data and color data

it can obtain 3 D point cloud with color and texture information. This method can complete 3 D reconstruction only needs hand-hold camera to shoot multiple images of the object

it can be used in 3 D acquisition in large scenes virtual reality（ VR）.
