We address the question of, what structure of a set of lines in space constitutes a critical configuration to three generally positioned cameras. By critical configuration, it is meant a set of lines in space whose image projections to the cameras do not allow unique determination of the cameraspsila relative positions in space. We approach the question by looking into the trifocal tensor of the cameraspsila a quantity tightly related to the camera geometry. We focus on structures of lines in… CONTINUE READING
