Excerpt from the Book
II. HISTORY OF STEREOSCOPE
It was in 1838 when world first saw the first ever stereoscope made by an English scientist and inventor Sir Charles Wheatstone. He firmly believed that human eyes can perceive depth information i.e. 3rd dimension when two separate images of same object taken from different angles are given to left and right eye. The brain fuses the two images and a solid three-dimensional object is realized.
In 1839 the first practical photography process was invented and so in Wheatstone's stereoscope drawings were used. This stereoscope had the advantage of being size independent for images to be viewed.
David Brewster rival of Sir Charles Wheatstone credited the invention of stereoscope to Mr. Elliot. Mr. Elliot was Mathematics Teacher and according to David Brewster, the idea of stereoscope was presented by him in early 1823. It was in 1839, a year later to Wheatstone’s invention of stereoscope; Mr. Elliot constructed a simple stereoscope without using lens and mirrors. Stereoscope was a wooden box with 18 inches * 7 inches * 4 inches dimension. Transparencies can be viewed easily as photography was yet to be invented in that year.

Frequently Asked Questions
What is the primary focus of this paper?
The paper provides a detailed survey of 3D imaging, covering its historical development from 1838 to modern-day technological advancements.
What are the central themes discussed in the work?
The central themes include the evolution of stereoscopes, the technical differences between active and passive 3D viewer systems, and modern depth-based rendering methods.
What is the ultimate goal of the research presented?
The goal is to highlight the contribution of various scientists to 3D imaging and review current research trends in depth map generation and 3D display technology.
Which scientific methodology is primarily addressed?
The paper employs a survey methodology, synthesizing historical technical records and reviewing contemporary academic literature on 3D imaging and DIBR techniques.
What does the main body of the text cover?
The main body covers the timeline of 3D photography, detailed explanations of stereoscopic devices, and the operational principles of various 3D visualization systems.
Which keywords best characterize this research?
Key terms include 3D Imaging, Stereoscope, DIBR, Active/Passive 3D Viewers, and Depth Map.
How does DIBR differ from traditional 3D TV systems?
Unlike traditional systems that require the transmission of two distinct video streams (left and right), DIBR uses an intermediate view and an intermediate depth map to render both views.
What are the main challenges associated with DIBR?
The primary challenge in DIBR is the appearance of occlusion holes during pixel-to-pixel mapping, which can vary significantly between frames.
Why were early stereoscopes like the Brewster device significant?
They introduced lens-based viewing, which reduced device size and enabled the creation of handheld stereoscopic devices, making 3D entertainment accessible to the masses.
