another fun SRV-1 Blackfin firmware extension - real-time frame differencing
Just added a couple of functions for storing a reference frame and differencing that reference frame against the most recently captured frame. This will be useful for laser range finding, by comparing frames with and without the lasers on, and it will also be quite useful for motion detection.
Here's an example frame sequence:
#1 - normal capture
#2 - normal capture with lasers on
#3 - reference frame captured with lasers off, frame difference shown
#4 - lasers now on, frame difference shown
Here's a motion detection example:
#5 - normal view before capturing reference frame
#6 - differencing enabled, no motion
#7 - differencing enabled, motion detected
More details on this test version of SRV-1 Blackfin firmware are found on the Surveyor Robotics Forum and code is posted to our SVN repository
