In a similar manner you can test the Vision Works install
cd ~/VisionWorks-SFM-0.88-Samples/bin/aarch64/linux/release/
./nvx_sample_sfm
You should see a running example of Structure From Motion in what appears to be a parking lot.
On the NVIDIA TX-2, the process is slightly different.
The samples are saved in /usr/share/. You must move them to a desired location before you can build them.
./usr/share/visionworks/install_samples.sh ~
This will move the samples to your $HOME directory. Navigate to this folder and issue a make command to build all VisionWorks-1.6 samples as shown above.
NOTE: At the time of writing, I was unsuccessful in installing VisionWorks 1.6 on my most machine. I was only able to install it on the TX-2. Code written in OpenVX using the NVXIO library will not move over perfectly from a TX-1 to the TX-2 because the NVXIO library has now been split into NVX and OVX, so editing of function calls and such will be required.
