Time of flight (ToF) sensors are preferred over other sensors due to their simplicity, efficiency, speed, cost effectiveness, and ease of installation. ToF sensors have various applications including 3D scanning and modeling, agriculture monitoring from drones, depth and distance measurements, industrial scanning, security through people counting, and object detection. However, limitations of ToF sensors include relatively high power consumption and heat generation during operation, as well as depth measurement accuracy of only about 1 cm.

1. TIME OF FLIGHT SENSOR
WHY ToF SENSORS IS
PREFFERED?
ROLL NO: 15251510-002

2. FOLLOWINGS ARE THE MAIN REASONS DUE TO
WHICH TOF IS CONSIDERED
Simplicity
Efficient
Better speed
Cost effective
Easy to install
Fast working

3. APPLICATIONS
3D shape by scanning by ToF cameras:
Used to create 3D models of structures and monuments. For examples in 2015
a drone with ToF setup successfully created a 3D image of Jesus Christ the
Redeemer statue in Brazil.

4. CONT…
In agriculture:
Drones with multispectral scanners are used by formers to manage the corps. Data
taken from multispectral sensors to protects crops from disease and infections. Also
help formers to calculate the correct amount of water, fertilizers and spray to use to
crops. Drones are changing the face of UK agriculture and the benefits of the
farming industry adopting drone technology as a crop monitoring tool.

5. CONT…
For depth measurement of water or distance measurements:
provide rapid measurement of distance between object and ToF sensors.
As a scanners in industries:
In industries these sensors are used for scanning of products and detect the
leakage and any defects in processing of packaging and then apply suitable
measurements to cover this defects.

6.  SECURITY:
Person-counting at secured gates for detection of undesired intrusions
Person-counting at airports and in mass transits systems for security or
statistical purposes.
Object detections in sensitive areas

7. LIMITATIONS:
The power consumption and heat generation of components are relatively
large at work. Long-term work requires good heat dissipation conditions, and
it needs to be continuously optimized for use on consumer electronic devices.
Depth accuracy is upto 1cm which is not too much satisfied
