Fast Mode#
运作原理#
In normal operating mode, blaze cameras take eight subframes per frame (image) at different frequencies. If the FastMode parameter is enabled, only four subframes are taken. If the OperatingMode parameter is set to ShortRange, the subframes are taken at high frequencies (100 MHz). If the OperatingMode parameter is set to LongRange, the subframes are taken at low frequencies (15 MHz).
这允许增加帧速率。它还减少了正常操作模式下使用八次曝光引起的运动伪影。不利的一面是，所得的深度数据将不太准确。在“长距离”模式下工作时，这最为明显。
By default, the FastMode parameter is disabled. The general recommendation is to only enable it if you require higher frame rates or you want to reduce motion artifacts.
启用 Fast Mode 的效果#
| 范围 | 精度 | Temporal Noise | |
|---|---|---|---|
| Short Range | 0.3–1.5 m（30 m 无模糊） | ±5 mm (0.5–1.5 m) | <0.3 mm (up to 1.5 m) |
启用 Fast Mode 时的短距离 | 0.3–1.5 m | ±5 mm (0.5–1.5 m) | <0.3 mm (up to 1.5 m) |
| Long Range | 0.3–10 m（30 m 无模糊） | ±5 mm (0.5–5.5 m) | <1 mm (up to 5.5 m) |
启用 Fast Mode 时的长距离 | 0.3-10 m | ±5 mm（最长 5.5 m） | <6 mm (up to 5.5 m) |
