Once accessible only to the likes of David Hasselhoff and Batman, autonomous driving is now finding its way into a range of consumer vehicles. Here, in following a car named Junior and its various progeny, we trace the recent history of driverless vehicles and the advances in optics and sensor processing that have made these vehicles possible. Sunrise, Nov. 3, 2007. The 11 robot cars line up in the starting chutes and, one by one, pull onto the course: a makeshift urban landscape built at the former George Air Force Base in Victorville, Calif. The autonomous vehicles – no drivers and no...Read full article

    frame rate
    Frame rate refers to the frequency at which consecutive images, or frames, are displayed in a video sequence. It is typically measured in frames per second (fps) and determines the smoothness and perceived motion of the video. In digital video, each frame consists of a snapshot of the scene at a particular moment in time. When these frames are played in rapid succession, the illusion of motion is created. The frame rate dictates how many frames are displayed per second, thus affecting the...
    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...
    tracking
    1. The process of following an object's movement; accomplished by focusing a radar beam on the reticle of an optical system on the object and plotting its bearing and distance at specific intervals. 2. In display technology, use of a light pen to move an object across a display screen.
