INTERACTIVE LAB · PERCEPTION

LiDAR geometry. Explore it.

Measure ideal ray intersections with an obstacle.

Educational browser model

Calculations run on this device. This does not execute ROS, Gazebo or hardware commands.

Explore the model

17 ideal rays across 180°. Circle radius 0.35 m. Maximum range 4 m. No noise or occlusion model beyond this circle.

Ready. Choose Run calculations to begin.

Calculated result

Nearest ray
1.36 m
Forward ray
4.00 m

What to investigate

Move the obstacle sideways and compare the forward ray with the nearest ray. Maximum-range output means no circle intersection within range in this ideal geometry, not a promise of safe travel.
