How to set the maxdisp value for a custom dataset?

[hillaric]

Does the maxdisp value has a influence on the result of inference time or the performance? Besides, the result does not work well on my own dataset, I guess it is the problem of maxdisp value.

Yes, different maximum disparity demands of your data could be the reason for bad performance.
Did you fine-tune the model on your data? This is often necessary for good performance, especially on data that does not closely resemble the traffic scenes of KITTI or DrivingStereo.
