Live Ego-Motion Estimation

Figure 1: Reconstruction made from a sequence of turntable im-ages. 1. Description This demo will show live (real-time, low delay) estimation of the motion of a perspective camera. Some scene points are also reconstructed. The reconstruction of structure and motion is based on the video input alone and performed on a regular PC-laptop without special hardware. The estimation will be shown in three ways: Real-time directly from a video file stored on the hard-drive. Real-time through the capture card with camera play-back as the external video source. Live from camera using both turntable and freehand motion. The system uses the techniques described in [1] and [2], among other things. Examples of reconstructions made from disk are shown in Figures 1 and 2. A screenshot of the demo running is shown in Figure 3. An example of real-time reconstruction from camera playback is shown in Fig-ure 4. An example of live reconstruction is shown in Figur
