A real-time 3D visualizer for the VL53L5CX multi-zone time-of-flight sensor, with IMU orientation tracking for basic room mapping.
The VL53L5CX measures 64 distances simultaneously in an 8x8 grid, from 2cm to 4m. Combined with a BNO085 IMU for orientation, we can accumulate points into a 3D map of the environment.
