How to make the coordinate system in the test generation visualization file the same as that in the data set? #15

Hello，Your work is excellent.I found that the coordinate system in the visual file generated by the test is different from that in the data set. I want the two coordinate systems to be the same. How can I operate? Your answer is very important to me. I look forward to your reply.It's important to me. Thank you in advance.

@bukeyan4318 you can reference the answer in #5.

@dlinzhao hello,In other words,How to make the XYZ coordinate system generated by the test consistent with the XYZ coordinate system in the original data set ? The XYZ coordinate system generated by the test is not based on the original data set.I look forward to your reply.It's important to me. Thank you in advance.

@bukeyan4318 At the preprocessing, the coordinate xyz will subtract its minimum. So, you can add the minimum from original data to the coordinate of test results. Please reference the preprocessing.

@dlinzhao Thank you very much. I understand. However, what makes me curious is why the XYZ coordinate should subtract its minimum value. I tried not to subtract the minimum value before retraining, and the code operation reported an error. I wonder why the minimum should be subtracted?

@bukeyan4318 Because the input data will be split into multi-blocks, you can refer to room2blocks.
