In this ppt you will know about LIDAR and IOT and also relation between both.

1. IOT FOR BETTER
UNDERSTANDING LIDAR

2. WHAT IS IOT?
➤ The Internet of Things (IoT) describes
the network of physical objects—
“things”—that are embedded with
sensors, software, and other
technologies for the purpose of
connecting and exchanging data with
other devices and systems over the
internet.
➤ IoT is the part of Embedded system, In
Embedded system we learn about how
to embed hardware to the software as
per our convenient.

3. WHY IOT IS HELPFUL IN
MY PROJECT
➤ Since I’m using Arduino or Raspberry pi with
LIDAR so here must me need to transfer data.
➤ For showing LIDAR’s output We must need to
use a screen, so developing a screen which I
will install in the vehicles we need to use IoT.

4. Working of LIDAR
LIDAR system incorporates a laser device, a navigational Inertial Measurement Unit
(IMU),a high-precision airborne Global Positioning System (GPS), and a computer
interface. The technology uses ultraviolet, visible, or near-infrared light to image objects.
The laser emits light pulses and detects the light reflected by the objects. The sensor
measures the time between the emission and return of the laser pulse and calculates the
distance travelled. Distance travelled is then converted to elevation. These measurements
are made using a LiDAR system's key components, including a GPS that identifies the X, Y,
Z location of the light energy and an IMU that impart the orientation. This process is also
called 'Time of Flight'(ToF) measurement (Figure 2). Contemporary LiDAR systems are
sufficiently powerful to fire up to 900,000 pulses every second.

5. A LiDAR replicates this process a million times per second and summarises the results in a
high-definition 3D map system. This 3D map contains data that is utilised for making decisions.
A LiDAR system measures the elapsed time it takes for emitted light to travel to the ground
and back.

6. LIDAR and IoT:
A few facets of LiDAR make it particularly useful in specific Internet of Things (IoT)
applications. LiDAR solutions play a pivotal role in delivering on the IoT's promise –
increasing safety, productivity and efficiency across a wide variety of applications for
smart cities, infrastructure, agriculture, medical, retail and beyond
LiDAR technology is an active remote sensing system which means that
the system itself generates energy which will be light in the form of a
rapidly firing laser to measure ranges and the exact distance of an object
on the Earth’s surface.
