LiDAR stands for Light Detection and Ranging. It is a remote sensing method that uses laser light to measure distances and create 3D models of objects and landscapes.
LiDAR uses a laser beam to measure the distance to an object by calculating the time it takes for the laser light to reflect back to the sensor. If an object is falling, the distance measured by the laser will decrease over time, indicating that the object is falling.
LiDAR can accurately detect the position and velocity of falling objects, which can be used for early warning systems and monitoring purposes. It can also differentiate between different types of objects, such as rocks and debris, which can help with identifying potential hazards.
LiDAR can only detect objects that are within its range and that have a reflective surface. It can also be affected by weather conditions, such as heavy rain or fog, which can reduce its accuracy.
By analyzing the data collected by LiDAR, it is possible to identify areas where falling objects are more likely to occur and take preventative measures, such as installing protective barriers or implementing warning systems. LiDAR data can also be used to track changes in the environment and identify potential hazards before they become a danger.
