XGRIDS L2 Pro, K1, & PortalCam Comparison
A comparison of Precision, Purpose, Portability and Perception
The XGRIDS Vision
XGRIDS makes LiDAR 3D scanners with cameras and AI to digitize buildings—giving architects, engineers, and builders quick, accurate models for every part of the project.
What Do Accuracy Metrics Mean?
Relative Accuracy: How much your measurements match each other within a scan—great for checking changes or seeing if parts line up.
Absolute Accuracy: How well your 3D scan matches up with true survey points or site plans.
3σ RMSE: Most points (about 99%) will be within this error range—so if it’s listed as “1 inch,” almost the whole dataset is that close to reality.
16 vs 32 Channels: What’s the Difference?
LiDAR “channels” are like individual lasers. The more you have, the more dots you get, making your 3D models smoother and able to capture bigger sites faster.
16 channel is best for smaller buildings and basic jobs.
32 channel is for complex sites, bigger areas, or projects demanding premium point density.
Point Cloud Thickness and Density
L2 Pro (16 & 32 channel): Point cloud thickness is about 0.4 inches—meaning models resolve individual surfaces very well and reduce “fuzziness” between walls or structural details.
PortalCam & K1: Exact published thickness is not listed, but point cloud resolution is expected to be similar or slightly less, since both are designed for rapid walk-throughs and site visualization, offering dense coverage especially in smaller/interior spaces.
