3d Photogrammetry Stereo vision or 3D Vision or 3-Dimensional View is a normal part of human vision and you have it in order to see 3D illusions and have normal depth perception.This is a essential thing for 3d photogrammetry operators.
2D-View means Two Eyes =Two Separate Views!
Photogrammetry
Human beings generally come equipped with two eyes and one head.
Unlike horses, humans have two eyes located side-by-side in the front of their heads. Thanks to the close side-by-side positioning, each eye takes a view of the same area from a slightly different angle. The two eye views have plenty in common, but each eye picks up visual information the other doesn't. Have you ever compared the different views of your right and left eye?

3D View means Two Eyes =Three Dimensions (3D)!
Each eye captures its own view and the two separate images are sent on to the brain for processing. When the two images arrive simultaneously in the back of the brain, they are united into one picture. The mind combines the two images by matching up the similarities and adding in the small differences. The small differences between the two images add up to a big difference in the final picture! The combined image is more than the sum of its parts. It is a three-dimensional stereo picture as well as 3d photogrammetry vision.
The word "stereo" comes from the Greek word "stereos" which means firm or solid. With stereo vision you see an object as solid in three spatial dimensions--width, height and depth--or x, y and z. It is the added perception of the depth dimension that makes 3D photogrammetry stereo vision so rich and special.
3D Photogrammetry Stereo vision or stereoscopic vision probably evolved as a means of survival. With 3D stereo vision, we can see where objects are in relation to our own bodies with much greater precision especially when those objects are moving toward or away from us in the depth dimension. We can see a little bit around solid objects without moving our heads and we can even perceive and measure "empty" space with our eyes and brains.
Here are just a few examples of general actions that depend heavily on Photogrammetry stereo vision:
• Throwing, catching or hitting a ball
• Driving and parking a car
• Planning and building a three-dimensional object
• Threading a needle and sewing
• Reaching out to shake someone's hand
• Pouring into a container
• Stepping off a curb or step
Are You Sure You have Got Stereo Vision?
If you're having problems seeing 3D photogrammetry vision, take the time to find out if a vision problem may be the cause. Stereo-vision and binocular vision problems are more common than you might think. At least 12% of people have some type of problem with their binocular vision.
If you have Got Stereo Vision, Count Your Blessings!
