Cameras that scan and render objects in 3D are now a standard feature in many smartphones, drones, robots, and automobiles. Paired with the right software, these cameras are making it possible to sense light levels, movements, and textures in more places, and at a lower cost, than was previously possible. - https://spectrum.ieee.org/transportation/sensors/3-types-of-3d-sensing-for-smartphones-and-selfdriving-cars
Everyone can be a photographer now with the advancements in photography over the years. The basic principles of optics and the camera can be traced back to the Chinese and Greeks philosophers in the 5th–4th centuries B.C., before Christ. The camera has been traced back to the Middle Ages pinhole camera. A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole) – effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect. (Pharr, 2017). |
