Video capture and post-processing technique for approximating 3D projectile trajectory

Pre- and Post-Processing for Video Compression

Hard projectile penetration and trajectory stability

We present a general framework to describe the dynamics of a hard projectile penetrating into a solid target. Rigid-body dynamics, differential area force law and semi-empirical resistance function are used to formulate the motion of the hard projectile. The proposed model is capable of predicting the projectile trajectory under various oblique and yaw angles. Critical conditions for the occurr...

3D video and free viewpoint video - From capture to display

This paper gives an end-to-end overview of 3D video and free viewpoint video, which can be regarded as advanced functionalities that expand the capabilities of a 2D video. Free viewpoint video can be understood as the functionality to freely navigate within real world visual scenes, as it is known for instance from virtual worlds in computer graphics. 3D video shall be understood as the functio...

Preparing for Post-catastrophe Video Processing

The spread of video surveillance systems and video phones means that video cameras are more ubiquitous than ever before. In the event of a catastrophe the video captured by these cameras is an important source of information for those directing the response. This information is currently either ignored because it is seen as inaccessible, filtered through the media, or requires a huge commitment...

A 3D Pattern for Post Estimation for Object Capture

We describe a new pose estimation approach for a 3D object capture system. This 3D pose estimation approach offers several advantages: increased visibility, robustness to lighting conditions, and improved reliability with evenly distributed errors. The calibration pattern is built using 3D conic features. We use simplex search to find the camera position and orientations that minimizes the erro...
