Your iPhone or Android has a ton of hidden goodies. Here are 10 handy tips for taking better photos, using back tap, magnifying and more. 10 useful iPhone and Android tricks to help measure ...
There are many variants of photogrammetry. One example is the extraction of three-dimensional measurements from two-dimensional data (i.e. images); for example, the distance between two points that lie on a plane parallel to the photographic image plane can be determined by measuring their distance on the image, if the scale of
The dating game may never be the same again, that’s right: the iPhone 12 Pro can measure people’s height. One of the new features on Apple’s most recent premium handset was the introduction ...
Length measurement, distance measurement, or range measurement (ranging) all refer to the many ways in which length, distance, or range can be measured. The most commonly used approaches are the rulers, followed by transit-time methods and the interferometer methods based upon the speed of light. Surveying is one ancient use of measuring long ...
The depth of field, and thus hyperfocal distance, changes with the focal length as well as the f-stop. This lens is set to the hyperfocal distance for f /32 at a focal length of 100 mm. In optics and photography, hyperfocal distance is a distance from a lens beyond which all objects can be brought into an "acceptable" focus.

By illuminating points with coherent light and measuring the phase shift of the reflected light relative to the light source it is possible to determine depth. Under the assumption that the true range image is a more or less continuous function of the image coordinates, the correct depth can be obtained using a technique called phase-unwrapping.
A Foca camera of 1947 at the Musée des Arts et Métiers in Paris. A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus.
