So are you simply walking around the vehicles while keeping the sensor pointed at them, sort of like a SLAM setup?
Anyone want to see something specifically?
Curious to hear how light depended the visual tool will be.
* sun in the lens will make pictures worthless?
* idem dito with low light conditions
* how well do rainy pictures work.
* same question with windy conditians, waving trees and brush?
don??t get me wrong, this is innovative and I think it has potential.

Exactly, however this is a time limit and the sensor will need to have a fix while you are walking.?ÿ The Point cloud is generated in the Leica office software call Infinity.?ÿ?ÿ

I think this is going to be the limitation with this antenna as its using cameras and not lidar. I have bright sun right now, and rain tomorrow.?ÿ
?ÿ
Ill make a quick video to show the results
?ÿ
Not ringing any bells at the moment but I just asked my dad Ray and he knew right away!?ÿ
Thank you for your business!?ÿ
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.?ÿ
Things I've learned playing with it.?ÿ
The Good
- It works!?ÿ
- Works great in direct sunlight?ÿ
- Works great in the rain and darker areas?ÿ
- 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.?ÿ
- 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.?ÿ
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.?
SHG
A tilt sensor and camera attachement for the top of a GRZ122 360 prism on a detail polle would be interesting, along with tracking mode on a TS16.?ÿ I wonder what sort of accuracy and definition that could obtain...
Perhaps on the TS20??!!
@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.
SHG
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?
