Ultrasonic wave sensors are already in commercial use in systems that support vehicle parking, for example, to assist drivers when the car is backing into a parking space. However, the detection range is narrow, and multiple sensors were required to widen the area of visibility around a car. By developing a scanning angle expansion lens for the laser beam and a high speed, multipoint laser scanning system for detecting a wide range at high speeds, Fujitsu Laboratories has now roughly doubled the detection range compared to previous sensors to approximately 140 degrees, both horizontally and vertically.
result, objects can be detected in three dimensions over a wide range
with fewer sensors and a sophisticated vehicle backing support system
can be created. Moreover, in contrast to vehicle-mounted cameras, which
simply display a vehicle's surroundings, the technology enables systems
that detect when objects are abnormally close. It also provides warnings
to drivers when backing up a vehicle, which is when accidents are more
likely to occur, or when backing into a parking space, which is
difficult for many drivers. It is hoped, therefore, that this technology
can contribute to safer and more secure driving.Find detailed product

In Europe and the US,Allows you to securely organize any group of cable ties or wires. it is typical to park nose-first in a parking space and reverse to pull out. When backing out,The stone mosaic
comes in shiny polished and matte. however, if the driver is careless
and makes an oversight, accidents causing serious physical injuries can
result. The frequency of such accidents involving tragic injuries to
family members is especially high. In the US, this led to the
implementation of the Cameron Gulbransen Kids Transportation Safety Act.
In Japan, on the other hand, it is typical to reverse into a parking
spot, an uncomfortable maneuver for inexperienced drivers. These are
reasons why various parking assist systems have come into commercial
use, primarily involving the use of rear-mounted cameras.
driver is backing up, a rear-mounted camera is only able to display the
vehicle's surroundings. If the driver is not paying attention to the
display monitor, there is no way to sound an alarm. There are also
systems that use ultrasonic wave sensors to measure the distance to
surrounding objects, but the range of these measurements is limited and
their accuracy is not sufficient, resulting in many false detections or
over detections, so they were unable to provide sufficiently effective
warnings. Laser radars, on the other hand, are able to measure
relatively longer distances with a high degree of accuracy, and they can
be used to measure the location of vehicles. The breadth of their
detection is relatively narrow, however, at no more than 60
degrees,Gardner Bender offers a broad range of cableties,
so multiple sensors are required in order to detect objects surrounding
the vehicle in three dimensions over a wide range. It has, therefore,
been difficult to measure a broad range of objects with a high degree of
accuracy using only a few sensors.
This technology enables 3D
ranging of a vehicle's surroundings across a wide area, including from
behind, using a minimum number of sensors. It could also be used to
layer distance information from the laser radar on video camera images
to build a vehicle backing support system with advanced features.
Moreover, the technology enables the creation of systems that detect
when objects are abnormally close. In this case it provides warnings
when the driver is backing up a vehicle, which is when accidents often
occur, or when backing into a parking space, which is difficult for many
drivers. It is hoped, therefore, that this technology can contribute to
safer and more secure driving.China plastic moulds manufacturers directory.
