ESP32 Drives Real-Time 3D Room Mapping With Tiny TOF Array and IMU
The article showcases a real-time 3D room-mapping setup using ST’s VL53L5CX 8×8 multi-zone TOF sensor, an IMU for orientation, and an ESP32 that streams orientation-augmented scan data as JSON to a PC. A Python viewer and ESP32 firmware on GitHub accompany the project, leveraging the sensor’s 4 m range and 60 Hz sampling, along with noise filtering and plane fitting to generate room maps.
