LRF3000A1 · 905 nm Laser Rangefinder Module

LRF3000A1 精度与量程测试条件

量程数字必须连同目标和条件一起看。LRF3000A1 的公开值为 ≥3,000 m (70%-reflectivity building target; clear weather; visibility ≥4 km.)。精度:±0.7 m (D ≤ 100 m); ±(0.7 + 0.003D) m (D > 100 m)。

怎么看测试条件

反射率是目标返回激光的比例:白板约 90%,建筑约 70%,草地和土壤 10–30%。能见度限制远距指标,因为雾霾会双程吸收脉冲。两款模块标的目标不同时,先换算到同一目标再比较;开放模块数据库 把每家厂商的条件列在数字旁边。
