Turn a Time-of-Flight Sensor into a 3D Scanner

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. ⏱️ TIMESTAMPS 0:00 - Intro & hardware overview 0:56 - Starting the viewer 1:24 - Understanding zone rays 2:24 - Clip to measurement 3:35 - IMU orientation tracking 4:17 - Filtering noise 5:58 - Plane fitting (Least Squares vs RANSAC) 8:19 - Mapping mode demo 10:31 - Limitations & wrap-up 🛒 COMPONENTS (~£24 / $30 / €28 from AliExpress) • ESP32 dev board: ~£4 • VL53L5CX ToF sensor: ~£5 • BNO085 IMU: ~£15 💻 CODE GitHub: https://github.com/ferrolho/VL53L5CX-... #VL53L5CX #TimeOfFlight #ESP32 #3DScanner #IMU #PointCloud #Arduino #BNO085 #ToF #RoomMapping #DIYElectronics #RANSAC #PlaneFitting #Robotics #SensorVisualization
