Why the made dataset is inaccuracy?

Why the made dataset is in accuracy? Sorry to bother you, I use the labelfusion make some datasets, but the dataset is inaccuracy, I don't know why, I think maybe the camera Intrinsics what I used is inaccuracy, but the prime sense's Low rgb camera resolution, so the camera calibration can't get a good result. Could you give some advice on how to solve the problem, thank you very much
