Video: Drone System Aids Photographic Lighting

Facebook X LinkedIn Email
CAMBRIDGE, Mass., July 17, 2014 — A small, autonomous helicopter can direct lighting just where a photographer needs it. Researchers at MIT and Cornell University developed the drone system to respond to the movements of a photographer and her subject using lidar and input from the photographer’s camera. They tested their concept by having the drone perform “rim lighting,” a difficult-to-produce effect where the subject is brightly lit only at the edges. “It’s very sensitive to the position of the light,” said Manohar Srikanth, a former MIT postdoctoral researcher who now works...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
