Purpose[edit | edit source]
The purpose of this tutorial is to assist students who are trying to create a depth image or point cloud using The Xbox Kinect.
Kinect: Procedures[edit | edit source]
Using Xbox Kinect's point cloud feature to scan objects for 3D Printing
Steps[edit | edit source]
- 1. Download Processings from http://processing.org/. The is a free IDE for creating interactive programs using 2D, 3D or PDF output.
- 2. Create a folder in "My Documents" and name is Processing
- 3. Create another folder inside Processing and name it “Libraries”, this is the folder where all the libraries associated with running depth data and cloud point data software will be stored
- 4. Download drivers and software from https://github.com/diwi/dLibs, download and unzip in the "libraries" folder
- 5. Install Drivers using the device manager and manually install each driver from "C:\Documents\Processing\Libraries\dLibs_freenect\library\kinect_driver_windows" folder. This path can be used to find all three drivers.
- 6. Install all three drivers manually using the device manager(Plug in the Kinect First).
-Follow the steps in the InstallingDrivers image. -Repeat the process for all three drivers.
- 7. Open Processing and navigate to file > sketchbook > libraries >dlibs_freeKinect > Examples > kinect_basic_3D_export_scan. This will open the code that will be able to scan and save a depth image. Press the run button at top left hand corner and a new window will appear showing the depth data. Press the M key to export mesh, data is saved in the kinect_basic_3D_export_scan folder in the processing folder in my documents.
Saving Point Cloud Data From Kinect[edit | edit source]
- 8. Open the point cloud library in the processing IDE
- 9. Press the "M" key to save the point cloud data. The file is saved in the kinect_basic_3D_export_scan folder in the processing folder.
- 10. The file extension is .obj. This means that the point cloud files are saved as object files and can be opened in any 3D software package.
Alternative Method[edit | edit source]
Purpose[edit | edit source]
With the proper easy to follow procedure one will be able to use the Kinect to capture a 360 degree 3D view of an object
RGB-Demo[edit | edit source]
- 1. Visit the RGB-Demo website, go to the "Download" page and download the all in one driver package named "Zigfu"
- 2. Extract the files from the .zip folder and install each driver manually going through the Control Panel > Device Manager > Kinect (Plug in/Disconnect the USB to the computer to find the right Com port if it is not recognized)> Properties > Hardware > Properties > Driver > Update Driver > Browse my computer... > Browse... > Find the extracted driver (Repeat for each driver, installing them in the order they appear in the Zigfu folder)
- 3. Download and extract the RGB-Demo software
- 4a. For 360 degree views try using calibrate-kinect-ir.exe. I have not had success with this execution file, but this may be because I did not install the drivers manually. I just realized this as a possible solution after reading my partners tutorial above. After calibrating the Kinect (or perhaps calibration is an unnecessary step), 3D scanning using rgbd-scan-markers should work to capture a 360 degree view point cloud. I will update this tutorial if I get this step working. Otherwise, the following steps will stay for a simple procedure to create a point cloud, mesh, and object file for a perspective view of an object.
- 4b. Use the rgbd-viewer or rgbd-reconstructor to see a color image and a RGB (red-green-blue) image through the Kinect
- Note: Use the execution files one at a time, otherwise they crash
- 5. Use the grab-mesh (automatically captures mesh) or rgbd-reconstructor (use start button) to capture a point cloud which is saved as a .ply (polygon) mesh in the RGB-Demo folder
- 6. Download and install MeshLab (search google)
- 7. Refer to our tutorial on cleaning up Point Clouds in MeshLab to push your project towards 3D printing
