Does Javad have standalone photogrammetry software?
I see that there is an option under the Triumph LS to purchase both the Camera Offset and Photogrammetry ($1500 each). Is the Photo option a software purchase?
At $1500 it would be much less than Datumate, and right about where the other competitors are.
(With their advertisements about the UAV market, I would expect that there would be photogrammetry software included, but perhaps from a third party.)
This is something that I don't know much about.
Here is the LITTLE I know:
The Camera Surveying that this unit is a FORM of Pixelated B/B int.
We take the focal length of a camera, and from that , we determine the ANGLE between Pixels.
So, we are now determining bearings from angles, derived from Pixels. And, generating coordinates on remote objects.

I believe it's all software, but at least for now it's limited to the Triumph-LS hardware.
Hello dmyhill,
JAVAD GNSS does not currently offer a standalone photogrammetry software package like Datumate.
Camera Offset Survey is a software option available for the TRIUMPH-LS RTK rover GNSS receiver system which allows you to perform photogrammetry in the field or back in the office using its internal camera. An excellent example of putting this functionality to work was documented by Shawn Billings, titled "Complete the Job with One Complete Tool," is available for your review on the JAVAD GNSS homepage.
The Camera Offset Survey option was originally named Photogrammetry. These options are the same. The TRIUMPH-LS online ordering page has been updated to remove the redundant Photogrammetry entry.

Good answers above, D.
The Javad Photogrammetry option doesn't automatically produce point clouds. Users manually identify common points in photos. This reduces processing overhead substantially, and is probably the more pragmatic approach for most users. (Point clouds would be useful for volumetrics). It looks like the Datumate software works similarly, although I don't know, I'm just guessing from the screen captures.
There has been discussion about making the same onboard software available in a desktop version, for easier user interface. The LS works great and is highly portable, but it would be simpler working at a PC, selecting points. The Javad Photogrammetry software is specifically limited to photos collected with the LS. The camera is calibrated and the photos include the RTK position of the internal camera (solved from the antenna to the camera based on manufacturing specs, compass direction and tilt readings), which makes for better results with fewer (or even no) photo control points, whereas Datumate appears to work with various cameras (fixed lens most likely a requisite). Also, I suspect that with Datumate the photos don't require precise positioning (given the platforms described). This probably means that additional photo control is required to orient and scale the resulting points.
I hesitate to limit the perceived usefulness of the photogrammetry option, but I believe it particularly excels at remotely determining coordinates of structures, such as buildings, utilities, fences, towers, overpasses, etc. From my limited testing, it is capable of remarkable accuracies - in some cases better than RTK alone would produce.
