Stereoscopy/Left Eye - Right Eye
Jump to navigation Jump to search
In this learning resource you see pairs of images that are taken for the left eye and the right eye.
Learning Tasks[edit | edit source]
- Watch a real 3D scene in a park, outside in the street or in your room with objects in different distance overlapping. Close your left eye and shortly after open it again and close your right eye. Explain how the and why the objects move to the left in the foreground and e.g. to right in the background.
- (Perspective Drawing on Mirror) Analyze the perspective drawing on a mirror. Explain how the 3D construction can be used to create a 3D scene for both eyes. How is the construction related to location of the point in the Geogebra scene.
- (Photogrammetry) Explain how the difference in both projections for the left and the right eye can be used with multiple images from different locations to reconstruct a 3D scene from a sequence of different images.
- (Create Left Eye Image and a Right Eye Image) Create two sample images similar of an object of your choice similar to the ones shown below. Keep in mind that you take the image with slightly horizontal difference for the left eye and the right.
- Keep the object of interest stagnant in both images
- rename the images for left eye and right, so that you can identify for which eye the image was recorded (e.g. tree_left_eye.png and tree_right_eye.png or tree_L.png and tree_R.png)
- Load the Stereoscopy Template image on the right with LibreOffice Draw to arrange both images under left and right black image mask. Then transparent image of the template mask is white.
