Installing OpenNI and OpenNI2 Libraries

The OpenNI and OpenNI2 libraries are essential, and they should have already been installed when you downloaded PCL 1.8.0 (page 18). However, sometimes they get skipped, so you can make sure by installing them directly, one at a time, as follows:

1. Open the following URL in a web browser to automatically download OpenNI: http://openni.ru/wp-content/uploads/2013/11/OpenNI-Win64-1.5.7.10-Dev.zip

2. Navigate to the computer’s Downloads folder where the zip file was saved.

3. Double-click the zip file, then double-click the file inside to launch the setup wizard.

4. In the Destination Folder window that appears, confirm the automatically generated path or change it, then click the Install button (Figure 34 left).

5. In the Windows Security window that pops up to confirm your intent to proceed, click the Install button (Figure 34 right).

6. During the rapid installation process:

• A visual timer indicates the remaining time.
• An error message may indicate the library is already installed.

7. When the installation process is complete, the Completed the OpenNI... window appears. Click the Finish button (Figure 35).

8. Repeat the above steps of this procedure to install the OpenNI2 library, substituting the following URL in Step 1 above. The Setup Wizard windows are nearly identical. http://openni.ru/wp-content/uploads/2013/01/OpenNI-Windows-x64-2.1.0.zip
