What is stereoscopy in remote sensing?
Stereoscopy, sometimes called stereoscopic imaging, is a technique used to enable a three dimensional effect, adding an illusion of depth to a flat image. A stereoscope facilitates the stereoviewing process by looking at the left image with the left eye and the right image with the right eye.
What is the principle of stereoscopy?
Stereoscopy is based on Porro-Koppe’s Principle that the same light path will be generated through an optical system if a light source is projected onto the image taken by an optical system.
How stereoscopy works explain the term stereoscopic vision?
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.
What is the fundamental principle of photogrammetry?
The fundamental principle used in photogrammetry is triangulation. By taking photographs from at least two different locations, so-called ‘lines of sight’ can be developed from each camera to points on the object.
What is stereoscopy in VFX?
Stereoscopy, or 3-dimensional stereoscopic filmmaking, is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. Stereoscopy creates the illusion of three-dimensional depth from two given sets of two-dimensional images.
What is stereoscopy in geography?
If you have normal or corrected vision in both eyes, your view of the world is stereoscopic. Viewing your environment simultaneously from two slightly different perspectives enables you to estimate very accurately which objects in your visual field are nearer, and which are farther away.
How are stereo images used in remote sensing?
In remote sensing applications photographs of the earth are taken and 3D topographic maps and computer models can be created using the stereo images.
Where can I find the principles of remote sensing?
An instructive Internet reference discussing the principles of remote sensing, with illustrations and images, is found at http://www.sci-ctr.edu.sg/ssc/publication/remote- sense/rms1.html. 15.3 REMOTE SENSING SYSTEMS Many contemporary mapping technologists collect information with a variety of instrumentation, collectively known as remote sensors.
What can stereo image pairs be used for?
Stereo image pairs are used to make digital elevation models (DEMs). A DEM can be used to determine the boundary conditions of hydrothermal circulation and water budget analysis in a geothermal area. Geologic mapping can also be done more efficiently with the aid of Stereoscopy and other remote sensing techniques.
What is the purpose of stereo satellite imaging?
Stereo Satellite imaging also called stereoscopy or 3D imaging is a photography technique originally developed for creating the illusion of depth in an image or set of images. Two pictures of an object are taken from slightly different angles allowing for depth to be perceived when viewing the images.
