PURPOSE: To obtain a distance measuring information with higher accuracy by correcting a distance measuring information by a photodetecting output obtained when performing an optically driving of a light source to remove error components attributable to the difference of reflection factor on an object ...

Currently, depth mapping systems rely on bulky binocular stereo rigs or a single camera paired with a laser or light-pattern projector that don't work well outdoors because objects move too fast and sunlight dwarfs the projected patterns. There are other machine-learning based systems also seeking...
This photo sensor (100) comprises: a plurality of avalanche photodiodes (APD) (10) provided on a first main surface (S1); a first separation region (21) provided on the first main surface, in which each of the plurality of APD (10) are electrically separated in a first direction; and ...
On the other hand, the computation of the distance measurement based on a photo-detecting element 7d is started while the finder 2 makes the parallax correction to a photographic lens 1 if the subject is at a short distance. Namely, the light emission of the light sources 6b, 6c is ...
The speed and distance measurements may be calibrated by skating a defined measured stretch and inputting a correction value. One or both skate shoes may be provided with permanent magnetic strips (1) co-operating with a reed relay (5) or a photodiode. the distance and position information ...
A calculation unit acquires a phase difference between the projected light and its reflection at a respective one of a plurality of points on the screen, acquires a distance from the projector to the respective one of the plurality of points on the screen, and then acquires an inclination ...
申请(专利权)人: FUJI PHOTO OPTICAL CO LTD 发明人: I Minoru 摘要: PURPOSE: To reduce the number of components and to measure a distance quickly and with high accuracy by a method wherein the distance up to a subject is operated on the basis of a shift amount which is used to make ...
PURPOSE: To provide a distance measuring device for an autofocusing apparatus which can surely focus even when there exist a plurality of subjects, prevent mismeasurement even when an error occurs in spatial quantization in image- formation on a light-receiving sensor and can measure a distance to...
a first integral, charging the integrating capacitor with constant current to produce a second integral, a maximum second integral time selector for selecting a maximum of the second integration times, and a detector for determining the distance based on the signal output by the integrator after ...
