Depth perception is the visual ability to perceive the world in three dimensions, coupled with the ability to gauge how far away an object is. Depth perception, size, and distance are ascertained through both monocular (one eye) and binocular (two eyes) cues. Monocular vision is poor at determining depth.

Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis.

When you look straight into distance, your eyes are parallel to each other. The brain “computes” the spatial information from the difference between the two pictures on the retina and creates a joint overall image, which provides extra information about distance to an object. This process is called stereoscopic vision.

Stereopsis (from the Greek στερεο- stereo- meaning “solid”, and ὄψις opsis, “appearance, sight”) is a term that is most often used to refer to the perception of depth and 3-dimensional structure obtained on the basis of visual information deriving from two eyes by individuals with normally developed binocular vision.

The term stereoscopic vision refers to the human ability to view with both eyes in similar, but slightly different ways. This allows humans to judge distance, which develops their ability to have true depth perception.

Taken literally, stereoscopic vision describes the ability of the visual brain to register a sense of three-dimensional shape and form from visual inputs. One example is singleness of vision: namely, the generation of perception of a single object by the two eyes by means of their co-coordinated use.

The researchers at McGill University have shown that one to three weeks of playing a dichoptic video game for one to two hours on a hand-held device “can improve acuity and restore binocular function, including stereopsis in adults”.

English Language Learners Definition of stereoscopic —used to describe an image that appears to have depth and solidness and that is created by using a special device (called a stereoscope) to look at two slightly different photographs of something at the same time.

Two photographs with sufficient overlap of detail to make possible stereoscopic examination of an object or an area common to both. Dictionary of Military and Associated Terms.

Anaglyph 3D

Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes.

We are 3D creatures, living in a 3D world but our eyes can show us only two dimensions. The miracle of our depth perception comes from our brain’s ability to put together two 2D images in such a way as to extrapolate depth. This is called stereoscopic vision.

A lack of depth perception can impact your life in several ways: It can affect a child’s ability to learn. It can cause problems driving and navigating roads properly.

Gaze at the stereo pair, keeping your eyes level (don’t tilt your head left or right), and cross your eyes slightly. As you know, crossing your eyes makes you see double, so you will see four images. Try to cross your eyes slowly, so that the two images in the center come together.

3D Stereo 180 VR shooting Tips

1. Align the horizontal lines of the lens.
2. Set the cameras horizontally and vertically.
3. Put sound at the beginning and the end of video.
4. Shoot the videos with the cameras facing forward.
5. The height of the viewpoint.
6. Know the sweet spot of the cameras.
7. Optimal distance feeling.

Stereographs consist of two nearly identical photographs or photomechanical prints, paired to produce the illusion of a single three-dimensional image, usually when viewed through a stereoscope. Typically, the images are on card mounts, but they may take the form of daguerreotypes, glass negatives, or other processes.

A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.

Most people can, with practice and some effort, view stereoscopic image pairs in 3D without the aid of a stereoscope, but the physiological depth cues resulting from the unnatural combination of eye convergence and focus required will be unlike those experienced when actually viewing the scene in reality, making an …

This is the phenomenon called stereoscopy. There are two basic types of stereoscopes for stereoscopic viewing of photographs, namely, the lens stereoscope and the mirror stereoscope. Each has advantages and disadvantages.

Your perfecscope is better known as a stereoscope and was made by Underwood and Underwood. Bert and Elmer Underwood founded their company around 1883. Collectors interested in seeing the pyramids along the Nile often are willing to pay in the range of $100 to $195 for similar stereoscopes and stereo view cards.

What makes the modern relevance of this invention particularly remarkable is that the stereoscope was invented in 1838, 180 years ago. The man responsible was Charles Wheatstone FRS, who published the first description of his stereoscope in the 1838 volume of the Philosophical Transactions of the Royal Society.

Values for Stereoscopes Antique stereoscopic viewers typically sell for $100-$125 and individual cards are valued based on their subject matter and condition. Most cards are traded in large sets based on a particular subject.

View-Master is the trademark name of a line of special-format stereoscopes and corresponding View-Master “reels”, which are thin cardboard disks containing seven stereoscopic 3-D pairs of small transparent color photographs on film. It was originally manufactured and sold by Sawyer’s.

As described, value is $12 to $15 apiece. If pricked, value is $50 to $150 each. As for the subject matter, French cardmakers specialized in diabolical or theatrical subjects.

Lens (or pocket) stereoscope has a limited view and therefore restricts the area that can be inspected where as in mirror stereoscope has wide view and enables a much larger area to be viewed on the stereo-pair. A stereoscope (Fig. 8.3) consists of a double optical system (lenses, mirrors, prisms, etc.)

Before The View-Master In the 19th century, stereoscopes, essentially 3D viewers that used cards called stereographs, were relatively popular. Starting in 1932, a company called Tru-Vue was producing viewers that used light and transparent film strips rather than picture cards.

The first thing you have to do is take some 3D pictures. Then, under adult supervision, glue some pieces of cardboard together with the right measurements to make a frame. Finally, tape some lenses to a piece of cardboard with eye holes and you have your stereoscope!
