Light Detection and Ranging (Lidar) imagery offers high resolution models of ground elevation, with vertical accuracy.  As  Lidar sensors have gotten smaller and lighter for use on drones, the use cases have expanded. Lidar imagery is flexible and precise, which makes it useful for professionals who want to understand a surface.  With Lidar, users can see the ground beneath the tree cover, or with Bathymetric LiDAR, the riverbed beneath the water.  Lidar’s high resolution maps are used for applications that range from archeology to disaster management.

Lidar data can be tricky to understand, however.  Without the context of traditional imagery, Lidar requires users to interpret what they are seeing.  Lidar scanners don’t typically capture color, including only elevation or intensity values.

SimActive Software Used to Colorize Lidar

 Now, SimActive Inc. announces the use of its lidar point cloud colorization capabilities by users of multi-sensor systems developed by LiDARUSA. SimActive’s Correlator3D™ software allows to profit from imagery and Lidar data in a complimentary fashion: making Lidar data easy to understand.

Lidar point clouds are first imported in Correlator3D™, to which the collected imagery is automatically registered.  The lidar data are used as control for the registration process.  Each lidar point is then colorized using the images.

“While lidar is great, everyone understands imagery. Colorizing lidar makes the data much more understandable”, said Jeff Fagerman, CEO at LiDARUSA.  “Correlator3D allows our clients to easily colorize lidar point clouds from their multi-camera system.”

SimActive is the developer of Correlator3D™ software, a patented end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including drones.
