Hi Eduardo,
Well, I believe that would require more complex lenses,
Yes. "No free lunch" :>
and might also introduce other problems into the system.
Possibly.
Why do you say that using the same clock for both cameras
will not work?
Because there are several "clock" involved in video that are
all "harmonicly" related (bad choice of words).
An image is composed of frames/fields (depends on whether the
image is interlaced or not). These occur at a fixed "frame/field"
rate. I.e., think of a "clock" that marks the start of a field/frame
and repeats as often as fields/frames repeat!
Fields/frames, in turn are composed of *scan lines*. Some number of
scan lines per field/frame. So, there is a fixed *line* rate! Think
of (another) clock that runs at some MULTIPLE of the field/frame clock
rate that marks the start of each successsive "scan line" and repeats
as often as the scan lines repeat!
Each scan line consists of some number of dots (pels). Some number of
dots per scan line. So, there is a fixed *dot* rate! Think of (yet
another!) clock that runs at some multiple of the scan line clock
rate that marks the start of each *dot* and repeats as often as the
dots repeat.
Which eventually determines how often the scan lines repeat.
Which eventually determines how often the field/frames repeat.
The "clock" you are thinking of is probably most closely related to
(though not necessarily identical to!) the dot clock.
If you drive two identical cameras with an identical clock signal,
all you can guarantee is that the dots are *sampled* at the same
rate. But, on any particular clock, camera 1 could be sampling
dot 27 of line 19 in field 0 while camera 2 is sampling dot 294 of
line 300 in field 1!
They aren't "looking" at the same thing at the same time.
If you can tolerate this, then you can probably tolerate the skew
that will invariably exist between two "free-running" cameras!
The project goal is to obtain good quality depth information using
the stereo system, and the images are not necessarily static.
Then if one "snapshot" of he image is 1/100th of a second skewed from
the other, in time, it will have moved relative to the image the other
camera is reporting.
In fact, I'm assuming the cameras can move at fairly high speeds.
Regarding the frame rate, I can achieve up to 30 fps with the C310 cams.
29.97 is all RS170 equired :>
