Hitachi Smart Data – 3D LiDAR

By Hubert Yoshida posted 07-27-2020 23:10


3D LiDAR is an excellent data source that complements many other types of data
to achieve smart spaces and smart operations. These additional data types could include video intelligence, internet of things (IoT) sensors, business data from ERP systems and so forth. We leverage IoT, video, lidar and data management solutions that help our customers reach the out- comes they seek.


Here’s how it works: A laser beam reflects off objects and people and is picked up by an extremely accurate charge-coupled device sensor that determines the time it takes the beam to return. This process allows the near infrared sensors to calculate the size, shape and position of objects. By repeating this process multiple times per second, 3D-LiDAR sensors track movement, referred to as Time of Flight (TOF). The sensors accurately track multiple objects at the same time and produce a 3D image of the space around those objects. Unlike traditional cameras that use visible light to capture details such as colors and facial features, the sensors record only the outline of people, thereby protecting privacy.


This technology has been widely used in autonomous vehicles (AVs) and geo- graphical mapping from drones. And new innovations have dramatically reduced costs to enable lidar for use in smart spaces such as retail, airports, event spaces, facilities, healthcare campuses and so forth. With the addition of machine learning techniques, this data can provide a wealth of valuable insights for enhancing operations, safety and customer experience.



Lidar is an ideal solution for gathering business, operational and safety insights and alerts in a variety of environments, without capturing private information.

o   Retail: Understand customer behavior and product interactions, including journey paths and dwell times for store optimization.

o   Smart Cities: Gain pedestrian data and alerts, and public space usage insights to optimize public services.

o   Healthcare: Gain GDPR-compliant patient alerts and behavior insights, handwashing verification for surgeons, and campus insights.

o   Manufacturing: Ensure assembly quality and gain slip-and-fall or safety alerts with movement analysis.

o   Transportation: Provide real-time vehicle occupancy, station usage and hazard alerts.  

o   Airports: Ensure on-time performance and customer experience with luggage volume sizing, gate analysis and lounge insights.

o   Critical Infrastructure: 3D scanning of infrastructure detects defects, obstructions and foliage to prevent damage or safety issues.

o   Physical Security: Detect tailgating, intrusions, dangerous objects, violent interactions and more in buildings, elevators and other areas.


New uses for LiDAR are being developed every day.

o   Differential Absorption LiDAR (DIAL) offers a new method of oil and gas exploration that is still in development. It uses Lidar ability to detect gases and particles

o   LiDAR pulses can penetrate deep into structures like bridges to identify faults that would otherwise go unnoticed.

o    LiDAR in combination with radar is being used to identify tumors in the body.

o   LiDAR can detect particles in both air and water, which makes it particularly adept at identifying pollutants like carbon dioxide, sulphur dioxide and methane

o   LiDAR can study the gas composition of the atmosphere, necessary for weather forecasting, climate modelling and environmental monitoring.

o   LiDAR can be used for topographic analysis and prediction of soil properties in agricultural landscapes. Using these insights, farmers can analyze, model and predict crop yields in any given place. 

o   It is ideal for monitoring social distancing without violating privacy
