InteractiveVirtual Simulation for Multiple Camera Placement

Camera placement plays an integral role in image-based 3D object reconstruction. Poor camera placement can lead to poor reconstruction if important silhouette or texture details are not captured in one view, if a camera is too close and the object silhouette is clipped, or if a camera is too far to provide a high-resolution capture. Some of these constraints are in contention. Manually adjusting real world cameras to satisfy these criteria is difficult and tedious as cameras may have to be unmounted and moved, their output checked for fitness of view, then readjusted. An interactive virtual camera positioning utility is presented that helps the reconstructor quickly and easily choose intuitively good positions, with emphasis on preventing clipping and resolution loss by visualizing the camera-set´s mutual viewable volume
