360 Degree Lidar Security System Range Upto 8m

The 360-degree LiDAR security system operates by combining active optical distance measurement with continuous rotational scanning, controlled via a Raspberry Pi 5. At the heart of the system is the YDLIDAR X2L module, which emits pulsed laser light and measures the time of flight or phase shift of the reflected beams to determine the distance to surrounding objects. Because the sensor physically rotates through a full 360-degree field of view, it continuously samples the environment across a radial plane, generating a dense array of distance and angle coordinates. Data from the YDLIDAR is transmitted to the Raspberry Pi 5 via serial communication over connecting cables. On the software side, the YDLIDAR SDK interfaces with the hardware to parse the raw data stream into usable coordinate points. Python 3 scripts utilize NumPy to efficiently process these coordinate arrays, translating polar data into Cartesian space for spatial analysis. Finally, Matplotlib renders these data points in real-time, visualizing the surrounding environment as a dynamic point cloud on a connected computer or monitor. When stationary objects shift or new objects cross the scanned perimeter, the software detects these anomalies against a baseline scan, enabling real-time perimeter monitoring and motion tracking.
