1. Lidar Introduction
1.1 T-mini Plus Lidar
The lidar used in this product is the T-mini Plus, a 360° 2D lidar. Based on the pulsed ToF ranging principle, together with associated optical, electrical, and algorithmic design work, the T-mini Plus achieves high-frequency, high-precision distance measurement. At the same time, its mechanical structure rotates 360 degrees to continuously acquire angle information, thereby achieving 360-degree scanning ranging and outputting point cloud data of the scanned environment.
1.2 Lidar Features
- 360-degree all-around scanning, 6-12Hz adjustable scanning frequency
- High-speed ranging, ranging frequency 4000Hz
- Small ranging error, good ranging stability
- Strong resistance to ambient light interference
- Class I eye safety standard
