The term camera is also used, for devices producing images or image sequences from measurements of the physical world, or when the image formation cannot be described as photographic: Acoustic camera which makes sound visible in three dimensions
This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial ...
3D camera may refer to: . Range camera, a device which produces a 2D image showing the distance to points in a scene from a specific point.; Stereo camera, a type of camera with two or more lenses with separate image sensors or film frame for each lens, which allows the camera to simulate human binocular vision, and therefore capture three-dimensional images.
While some film cameras could reach up to 14 frames per second (fps), like the Canon F-1 with its rare high-speed motor drive, professional DSLR cameras can take still photographs at the highest frame rates. While the Sony SLT technology allows rates of up to 12 fps, the Canon EOS-1D X can take stills at a rate of 14 fps.
A structured-light 3D scanner is a device used to capture the three-dimensional shape of an object by projecting light patterns—such as grids or stripes, onto its surface. [1] The deformation of these patterns is recorded by cameras and processed using specialized algorithms to generate a detailed 3D model.
Digital cameras can easily adjust the film speed they are simulating by adjusting the exposure index, and many digital cameras can do so automatically in response to exposure measurements. For example, starting with an exposure of 1/60 at f /16 , the depth-of-field could be made shallower by opening up the aperture to f /4 , an increase in ...
In computer vision, 3D object recognition involves recognizing and determining 3D information, such as the pose, volume, or shape, of user-chosen 3D objects in a photograph or range scan. Typically, an example of the object to be recognized is presented to a vision system in a controlled environment, and then for an arbitrary input such as a ...
Computational speed is restricted by the file sizes of 3D images, which are significantly larger than 2D images. For example, an 8-bit (1024x1024) pixel 2D image has a file size of 1 MB, while an 8-bit (1024x1024x1024) voxel 3D image has a file size of 1 GB. This can be partially offset using parallel computing. [13] [14]
