question: How do cars have cameras that broadcast the top of the car and the surrounding area?
comment: It's not the top of the car. It's most commonly 4 cameras. One in the front, one on each side and one on the back. Through editing you attach them all together showing the different sides and put the car where there's a missing spot (I. E. In the middle) that's how you get a faux 360 camera - you should still actually look around as you back up though
passages: As with US onboard coverage, F1 used a helicopter as a local satellite to pick up the transmission from the cars and re-broadcast it to the truck / local production center. This was initially shifted to a ground-based analog system, with variable results, and more recently to a ground-based digital solution which is now the norm. Onboard cameras are now commonplace in other top motorsports including the World Rally Championship and MotoGP.

   BULLET::::- The oldest and most common method, called Over Head System (OHS), uses a conductive floor and ceiling, each with a separate power polarity. Contacts under the vehicle touch the floor while a pole-mounted contact touches the ceiling, forming a complete circuit.
   In recent years, the use of body worn video cameras has been introduced for a number of uses. For example, as a new form of surveillance in law enforcement, with cameras located on a police officer's chest or head.
  
  Section::::Uses.:Traffic monitoring.
  
  Many cities and motorway networks have extensive traffic-monitoring systems, using closed-circuit television to detect congestion and notice accidents. Many of these cameras however, are owned by private companies and transmit data to drivers' GPS systems.
   Specific tests have been led on a tower-test platform in Livorno (Italy). The test used 2 cameras filming simultaneously a target meanwhile the pole was submitted to dynamic oscillations. One being fixed on the pole and the other on the top platform. The results of this test are shown on an external website .
   On May 13, 2009, Google Japan announced that it would modify their cameras to scan from a lower height of 2.05 meters above ground level, 95 centimeters lower than the original height of the camera head. The new height is intended to avoid having cameras view over fences in front of homes and into homes. This reduced height is to apply immediately, and all areas previously visited will be rescanned from the reduced height. Scans taken at the original height will remain available until they are replaced with the new images. 
   Inside the car body is a transmitting RF module (Richwave "RW67TX-NA03") and a black-and-white camera module (based around the OmniVison OV5116 IC). Similarly, the remote control unit contains a corresponding video receiver (Richwave "RW67RX-NA03") and a 3.5 mm phono jack which carries the video signal to the headset. The headset is based around the Kopin CyberDisplay 300M LV LCD and A300 controller IC. It contains simple optics and a diffused, white LED backlight. All of the components run on a 9v DC source (each has its own voltage regulator), and the Rx/Tx set operates on the 2.4 GHz range.

  A HMD system has been developed for Formula One drivers by Kopin Corp. and the BMW Group. The HMD displays critical race data while allowing the driver to continue focusing on the track as pit crews control the data and messages sent to their drivers through two-way radio. Recon Instruments released on two head-mounted displays for ski goggles, MOD and MOD Live, the latter based on an Android operating system.
  
  Section::::Applications.:Training and simulation.
   This system is linked by an industry-standard fibre optic network known as Media Oriented Systems Transport or MOST and an electronic network system known as CAN bus. A similar system is also used on Land Rover Discovery and Range Rover Sport.
   The first time a live onboard camera was used in a Formula One race was at the 1985 German Grand Prix, where one was attached to François Hesnault's Renault. Previously, cameras had only been mounted to F1 cars during testing, but since then, more and more cameras have been fitted. Since 1998, all Formula One cars have been fitted with at least three onboard cameras (usually more) and they form an integral part of the television coverage.

  Section::::Active systems.:Toyota.
  
  In 2002 Toyota Night View was the first worldwide series production active automotive night vision system, introduced on the Toyota Landcruiser Cygnus or Lexus LX470. This system uses the headlight projectors emitting near infrared light aimed like the car's highbeam headlights and a CCD camera then captures that reflected radiation, this signal is then processed by computer which produces a black-and-white image which is projected on the lower section of the windshield.
   The tall spar contains the Sony HD camera, the pan and tilt motor, and stabilization sensors. Weighing , the package also includes a power distribution module and electronics for fiber optic signaling.
  
  Section::::Technical overview.:Central control.
   Digital eye-tracking cameras – designed around state-of-the-art CMOS image sensors – are interfaced to a dedicated processor board in the host PC via bi-directional, high speed digital transmission links (400 Mbit/s). This PCI plug-in board carries the front-end processing architecture, consisting of digital signal processors (DSP) and programmable logic devices (FPGA) for binocular, online image and signal acquisition.
   In a common omniview system, there are four wide-field cameras: one in the front of the vehicle, one in the back of the vehicle, one in the left rear view mirror, and one in the right outside mirror. The four cameras cover the whole area around vehicle. The system synthesizes a bird view image in front of the vehicle by distortion correction, projection transformation, and image fusion. The images shown below are input and output of a common omniview product.

   Cameras are another electronic safety device used for press brake safety. The camera can detect an intrusion between the upper and lower dies. If an intrusion is detected, a signal will stop the downward movement of the ram. A camera safety system uses a linear scale to calculate the upper beam's position, velocity, and the stopping distance.

   To form an image of the antenna above it, the ground plane need not be grounded to the Earth. Many antenna types, such as reflective array antennas, use flat surfaces of metal or metal screen to reflect radio waves from the antenna elements, and these can be analyzed using image antennas. If there is more than one reflective surface in the antenna, as in a corner reflector antenna, each surface forms its own image of the antenna elements. In order to form an image, the ground plane surface must generally have dimensions of at least a quarter-wavelength of the radio waves used.
   Each car must know where it is in relationship with other cars; it does this by transmitting its position to the control tower and receiving the positions of other cars over a spread spectrum radio to avoid the noise of power pickup wipers arcing along the bus bar. The vehicle also responds to programming selections indicated by a section of track and reports which subprogram it is currently running.

   Section::::Cable-mounted camera systems.
  
  Skycam is the original, elevated cable-controlled camera system that was invented by Garrett Brown in 1984; who also invented the body-mounted Steadicam system.
  
  Because of its ability to carry heavy loads and provide smooth, precise camera movements and maintain steady camera positions, the Skycam and CableCam-type systems are primarily used as a remote-controlled camera, for mobile television productions, at major stadium events. The Skycam utilizes the buildings superstructure to anchor its cable and pulley system.
   BULLET::::- Top-mount sliding sunroofs (rail mount topslider) have been a popular factory option in Europe for many years. A large glass panel slides open in tracks on top of the roof, with no loss of headroom. Most feature an integral wind deflector to eliminate wind noise. Examples include Donmar's original Skyroof topslider (aftermarket system), the London Taxi and Renault 5 cars.
   Often with alignment equipment, these "heads" can be a large precision reflector. In this case, the alignment "tower" contains the cameras as well as arrays of LEDs. This system flashes one array of LEDs for each reflector whilst a camera centrally located in the LED array "looks for" an image of the reflectors patterned face. These cameras perform the same function as the other style of alignment equipment, yet alleviate numerous issues prone to relocating a heavy precision camera assembly on each vehicle serviced.

  In 2007 Nissan introduced their "Around View Monitor" on the 2008 Infiniti EX35, which uses four cameras to give a bird's eye view of the vehicle. Other automobile manufacturers have since offered similar systems. BMW introduced their competing system called Surround View in 2009 on the F10 5 Series.
  
  Wireless Backup Camera
   The new generation of robots conceived by the inventor has cameras set in their “eyes” and “shoulders” that film traffic continuously. Thanks to the antenna fixed on top of their head, data can be transmitted to a control center via an Internet Protocol (IP) transmission.
   Much of the original development work which led to the onboard cameras used today was performed by Australia's Seven Network, which introduced the technology at the 1979 Hardie-Ferodo 1000 endurance race at Mount Panorama. 
  
  The original, Channel Seven, development team of John Porter and Peter Larsson moved to the states and formed Broadcast Sports Technology Inc.. BST then proceeded to recruit other staff from Channel Seven, notably Michael Katzmann.
   To capture as much telemetry data as possible, custom circuitry termed 'sensor nodes' were developed. Sensor nodes are designed so they can all communicate to each other across the length of the vehicle, as well as each individual node being able to interface with over 20 different sensors each. This also allows some data to be relayed to the driver via the dashboard.

   As far as resolution goes, WAMI systems usually have a 0.5 meter ground sample distance (GSD)—enough to detect and track moving targets throughout the scene. Should a user need to take a closer look at a subject, the WAMI system can cue other available sensors, such as hi-res full-motion video cameras, to make the identification.
   The first backup camera was used in the 1956 Buick Centurion concept car, presented in January 1956 at the General Motors Motorama. The vehicle had a rear-mounted television camera that sent images to a TV screen in the dashboard in place of the rear-view mirror. 
  
  Later the 1972 Volvo Experimental Safety Car (VESC) had a backup camera. However, the camera element did not make it into the following Volvo 240 model.
