How to save the Kinect Cloud data faster?

[OsuQQ]

I found that saving a cloud frame is quite time-consuming. For tha resolution of 1920*1080, it takes about 15 seconds! My computer has 16G ram and GForce980. I think other computers with lower computation power my cost more time. Do you have any suggestions for improving the real-time performance of the "Cloud Save.vi"?

Saving a 3D cloud is expected to be time consuming. 15 seconds seem a little bit on the slow side though but certainly not impossible. Speed will depend mostly on the speed of your hard drive.

To make things as fast as possible, you should

1.       Select a more reasonable resolution. With the 1920*1080, you over-sample the resolution of the Kinect by a factor 8. The sensor is 424*512. If you select 960*540, you over-sample by a factor slightly over 2. If you selection 480*270, you under-sample by a factor slightly below 2.

2.       Select the format PLY Binary.

3.       Select a rate of data saving that is reasonable.

4.       Consider using a producer-consumer pattern (one or two loops for data acquisition and UI, another loop just for data saving.

5.       Select a fast hard drive, solid-state if possible.

6.       Make sure your drive is defragmented…

Good Luck
