@wong how can i change the minimum distance, and can i do it ? if it yes show me which program should i change, and i’ll ask again, is this distance data already in centimeters ? because the data is still in matrix form, please reply ASAP, thank you.

The minimum distance depends on the size of the baseline and is currently fixed.
But you can increase the search range when configuring parameters. -
Yes, the z unit should currently be cm
Did you test whether the distance is accurate in the case of a long-distance?
@wong please answer my question regarding to changing the minimum distance, and how many meters away, i don’t have much time, thank you
@wong, yes i have done that and this is my result, and the actual distance is around 150-160cm for each steps, and how can i increase the search range when configuring parameters ? is it from dm tunes or do you have another way ? and can it decrease the minimum range ? please reply ASAP, thank you. 
Since the hardware is fixed, you cannot modify the baseline, so the minimum distance cannot be changed. The current minimum distance is about 0.8m.
The parameter modification method is as follows:
