In the previous article, I set up a stereo vision rig. Now, its time to take pictures with it. The most important thing to do is to set things up so that the synchronized capture works correctly.
The cameras I used are Blackfly S cameras which use the Spinnaker API. I’ve opted to use the python version of the API because python is great for tinkering. The first thing to do is to go onto Flir‘s website, search for Spinnaker, and then download and install the SDK and Spinnaker for python. I’ve opted to use Ubuntu 16.04 with Spinnaker version 220.127.116.11.
After you install the SDK and python extension, take a look at the documentation for synchronized capture. If you scroll down to configuring Blackfly S cameras, you must:
- For the primary camera: 1) enable the 3.3V output for line 2
- For the secondary camera: 1) set the trigger source to line 3, 2) set the trigger overlap to “read out”, and 3) then set trigger mode to “on”.
