Photogrammetric Potential of the Canon EOS 5D MkII for Precise Still and Video Measurements

摘要

The Canon EOS 5D Mark II camera is a Single-Lens Reflex (SLR) digital camera with 21.1 million effective pixels and with a capability of recording full 1080 pixels High Definition (HD) video. Using still images acquired from high resolution SLR cameras, it is possible to measure precise three dimensional (3D) coordinates of well defined targets using close-range photogrammetric techniques. However, the use of images extracted from a video for such precision measurement is still challenging. The aim of this paper is to illustrate the results of using the video images of the Canon EOS 5D for precise measurements. The paper will firstly describe the technique used for camera calibration including for the video. Then, it will discuss and analyse the results of selected sets of images acquired using both video and still mode.
