What are Point Clouds?
Simply put, point clouds are plotted data points that represent space. A single point is plotted in an X, Y, Z coordinate and will represent an underlying sampled surface. Multiple data points will collate into multiple spatial measurements and therefore can effectively represent entire interior or exterior spaces. Sometimes, additional data, like color and luminance value, can be stored in an RGB format.
Laser scanners emit infrared light waves that reach out and touch the surrounding surfaces. Objects in the laser path then reflect the light back to the sensor. The sensor uses this information to determine how far away the object is. This is called a “time-of-flight” measurement. The time-of-flight measurement is calculated for every surface of the object. A laser scanner can collect millions of data points in just a few seconds. The distances measured on the structure are made into coordinates. When these coordinates are processed, they build a digital model of the spaces that were scanned. The model includes accurate dimensions, topographic features, and objects, providing a full scope of object data.
At Robotic Imaging, we use LiDAR technology to collect point cloud data. A laser scanner can collect millions of data points in just a few seconds. The distances measured on the structure are made into coordinates. Each point from a LiDAR scan represents a single scanned measurement, which is highly accurate then stitched together to accurately capture the built environment. This process is called “registration.”
Point clouds are typically converted and then translated into BIM models, which are valuable to architects, developers, and construction managers. It's ideal for construction and restoration projects given the precision guaranteed by the LiDAR technology.
Point clouds are the most accurate, pain-free method of measuring buildings and their properties. These measurements produce the most precise and detailed data in comparison to other surveying technology.
