LR1200D23 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。LR1200D23 的公开值为 4 m – 1,200 m (max. 1,200 m) (Target reflectivity, target dimensions and atmospheric test conditions are not stated in the reviewed public technical table; confirm the applicable controlled document.)。精度：δ ≤ ±1 m, 4 m ≤ d < 1000 m¹) (Standard version: ±1 m)。
公开的量程、精度与更新率
| 参数 | 公开值 | 条件 / 备注 |
|---|---|---|
| Measurement range | 4 m – 1,200 m (max. 1,200 m) | Target reflectivity, target dimensions and atmospheric test conditions are not stated in the reviewed public technical table; confirm the applicable controlled document. |
| Ranging accuracy | δ ≤ ±1 m, 4 m ≤ d < 1000 m¹) (Standard version: ±1 m) | The reviewed public technical table carries a ¹) marker without defining that footnote. Target reflectivity, target dimensions and atmospheric test conditions are not stated there; confirm the applicable controlled document before using this accuracy figure. |
| Measurement frequency | 2–10 Hz | |
| Ranging Resolution | Typical resolution: 10 cm | |
| Valid measurement rate | ≥ 98% | |
| False alarm rate | ≤ 1% | |
| Baud rate | 115200 bps |
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。
