内置RVC2

此OAK设备基于 RVC2 架构构建,主要特性包括:

功耗

大部分功耗由RVC2消耗,因此功耗主要取决于VPU的工作负载:
  • 基础功耗 + 摄像头流:2.5W - 3W
  • AI子系统功耗:最高1W
  • 立体深度管线子系统:最高0.5W
  • 视频编码器子系统:最高0.5W
为降低功耗,可以降低整个管线的帧率(FPS),这样子系统不会满负荷运行,功耗也会降低。

IMU

此OAK相机集成有BNO086,一款9轴IMU(惯性测量单元)。 有关如何使用的API详情,请参阅IMU node

工作温度

基于 RVC2 的设备在完全使用 VPU 时的环境工作温度介于 -20°C 至 50°C 之间。功耗类似,最高工作温度取决于 VPU 使用率。VPU 使用率越高,VPU 产生的热量就越多。RVC2 VPU 可连续在 105°C 下运行,超过此温度后,depthai 库将自动关闭设备(以避免芯片损坏)。如需了解更多信息,请参阅我们的 工作温度文档。

Theoretical depth accuracy

As M12 lenses are swappable, user can easily change lenses to achieve wider FOV, or longer depth perception (narrower FOV):
HFOV [°]< 2% depth error< 4% depth error< 8% depth errorMinZ

2027.2 m68.1 m136.1 m95 cm

4013.2 m33.0 m65.9 m46 cm

904.8 m12.0 m24.0 m17 cm
1004.0 m10.1 m20.1 m14 cm
Note: we haven't tested all of these combinations, but calculated theoretical depth error and interpolated those values with our previous real-world tests when enabling subpixel disparity:
  • < 2% error - 20th disparity pixel, which has 5% full-pixel error (~2% with subpixel enabled)
  • < 4% error - 8th disparity pixel, which has 12.5% full-pixel error (~4% with subpixel enabled)
  • < 8% error - 4th disparity pixel, which has 25% full-pixel error (~10% with subpixel enabled)
Maximum depth was calculated by using the large (15cm) baseline, while MinZ was calculated by using the small (5cm) baseline of the OAK-D-LR. You can further decrease MinZ by lowering the resolution, or using disparity shift (docs here). MinZ values are already using Extended Disparity Mode.

Tested lenses

Lenses from 3 different lens kits were tested with the OAK-D LR device. The tables below show which lenses fit the device enclosure, what is their (measured) HFOV and if they match the sensor's size.In the device OAK-D LR, the sensor AR0234 with the size of 1/2.6'' is used. The lenses need to be wide enough so the light reaches the entire sensor. The Notes columns in the tables show whether the lens is big enough for the used sensor. The vignetting effect link is seen where the lens doesn't fit the sensor's size.
