At least you know instantly when the images are fine for further processing and calculations! That a good thing for sure!
I have struggled to make a video as my screen capture software is only showing half the screen. I have some rough videos i can post but its not great.
Things I’ve learned playing with it.
The Good
- It works!
- Works great in direct sunlight
- Works great in the rain and darker areas
- Works great on edges of things or places with different color like a line line for example
- The field and office side of it is very easy to use, especially the field side.
The Bad
- You need to have good RTK data obviously. If you lose lock you will need to stop and re-walk that section. Not that big of a problem but i think it needs to be mentioned.
- It a little difficult to get good data in direct sunlight into a dark shaded area.
- doesn’t work well on areas that don’t have a defining feature. This makes sense, it needs something to define in multiple photos.
@eric-kara
thanks, appreciate te feedback!
@eric-kara
After a bit of testing, are the photo points still 0.1 feet? Is that true for well defined paint stripes, angle points in parking lot lines, etc.?

@nate-the-surveyor here is a link to the brief wiki explanation.

They aren’t quite on par with mechanical IMU’s yet (as far as drift rates), but dang close, especially in an application where they are steered by GNSS positioning, good enough at a fraction of the cost with no moving parts.

A lot of new Chinese receivers offer IMU tilt compensation up to 60 degrees without calibration.
Has anyone experience with this new technology? Is it reliable?
