LRF1831C 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。LRF1831C 的公开值为 a) Under line-of-sight conditions, with visibility not less than 15 km and humidity not greater than 80% (at 30 °C), the ranging distance for Target 1 (5 m × 15 m) is ≥ 6,500 m. b) Under line-of-sight conditions, with visibility not less than 15 km and humidity not greater than 80% (at 30 °C), the ranging distance for a target with diffuse reflectance not less than 30% (20 m × 20 m) is ≥ 12,000 m.。精度：±2 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。
