setSubpixel(True) only get 3 fractional bits

Hi,

I tried to enable subpixel setting by following code:

pipeline = dai.Pipeline()
depth = pipeline.create(dai.node.StereoDepth)
depth.setSubpixel(True)

But when I check the output of disparity, the maximum disparity only 760 not 3040, which implies I only got 3 fractional bits.

But the document say, I should get 5 fractional bits precision. What am I missing?

If default is 3 fractional bits, then how can I set 5 fractional bits?

Please help.

Thanks.

buried in algorithmControl API:

to set desired disparity fractional bits (3 by default) to 5:

currentConfig =  depth.initialConfig.get()
currentConfig.algorithmControl.subpixelFractionalBits = 5
depth.initalConfig.set(currentConfig)
