“…This shortcoming revealed the necessity for further development of a SIM using a single camera; also known as a planar catadioptric stereo (PCS) system 6, 11-12 . The PCS system has several advantages over conventional dual-channel SIM including convenient adjustment of the system parameters such as brightness, gain, and offset, and the hardware system for the camera synchronization can be simplified as only a single camera is used 13 .…”

This paper introduces a stereoscopic video imaging modality based on a transparent rotating deflector (TRD). Sequential two-dimensional (2D) left and right images were obtained by rotating the TRD on a stepping motor synchronized with a complementary metal-oxide semiconductor camera, and the components of the imaging modality were controlled through general purpose input/output ports using a microcontroller unit. In this research, live stereoscopic videos were visualized on a personal computer by both active shutter 3D and passive polarization 3D methods. The imaging modality was characterized by evaluating the stereoscopic video image generation, rotation characteristics of the TRD. The level of 3D conception was estimated in terms of simplified human stereovision. The results show that singlechannel stereoscopic video imaging modality has the potential to become an economical compact stereoscopic device as the system components are amenable to miniaturization; and could be applied in a wide variety of fields.

“…The first approach is a replacement of camera components, such as lens or CCD sensor by sliding along the left or right direction [9]− [11]. Various cameras are used to capture stereo images, such as toed-in camera [12], planar camera [13], [14], and so on.…”

Recently, various devices for three-dimensional (3-D) effect have been developed. For producing 3-D effect of the scene or the region of interest (ROI), disparity should be accurately estimated. People watching 3-D video feel visual fatigue if magnitude of parallax for the ROI is excessively large because a convergence point is not accurately put on the ROI. For producing 3-D effect, a 3-D formatter overlaps left and right images by shifting horizontally the right image by the estimated disparity of the ROI. In this paper, an adaptive disparity estimation algorithm for auto convergence of the ROI in a video is proposed using the first-order Taylor series expansion of disparity and adaptive disparity search range prediction in a stereoscopic video. First, a stereo video that consists of a number of pairs of left and right images is captured in parallel stereo camera configuration. A window in each frame

Stereoscopic technologies continue to accelerate the adoption of 3-D in both professional and consumer applications. Stereo 3-D displays have the potential to benefit geospatial intelligence, complex visualization, pharmaceutical development, petroleum exploration, medicine, entertainment, architecture, simulation, and other difficult tasks. A single-mirror dual monitor stereoscope system that can offer the full resolution of the current LCD display for 3-D viewing is proposed. This new approach utilizes an isosceles trapezoid mirror and two monitors to provide a cost-effective approach for stereoscopic viewing. Mathematical formulas for the design of the compact mirror were derived based on a novel scheme, and an implementation of the system was conducted to verify the practicability of the proposed method. We believe its compactness, low cost, and high image quality can become a very competitive choice among various display techniques currently available. © 2010 Society of Photo-Optical Instrumentation Engineers.
