Help with oblique imagery - setting up the Cameras table

[FilipJung]

Hi,

I would like to test the Oblique viewer sample and for that I need to prepare the Mosaic Dataset and publish it. I have found some sample datasets here: https://www.sensefly.com/drones/example-datasets.html

I have tried the sample called "Oblique imagery"

I created and populated Cameras and Frames tables and created Mosaic Dataset using these tables. Rasters are loaded, but the distortion parameteres seem to be not set up properlly because Footprints looks unreal:

My Camera table looks like:

OBJECTID

CAMERAID

FOCALLENGTH

PRINCIPALX

PRINCIPALY

A1

A2

B0

B1

My Frames table sample is:

OBJECTID	Omega	Phi	Kappa	SRS	CameraID	NCols	NRows	NBands	PixelType	Raster	PerspectiveX	PerspectiveY	PerspectiveZ
1	45.899019	-7.362863	175.289717	32632	[0]	4000	3000	3	8_BIT_UNSIGNED	...\IMG_7719.JPG	313636.698978	5162861.933003	714.078282
2	45.912378	-2.495157	171.893432	32632	[0]	4000	3000	3	8_BIT_UNSIGNED	...\IMG_7720.JPG	313643.441509	5162858.355595	713.06864

Can anyone please check my values?

Thanks in advance.

Hi Cody and thanks for your answer.

I will explain what i want to achive with the oblique viewer so maybe you can tell me if this is the right solution or not.

I want to create a webapp with oblique images from north-south and east-west with images taken from a drone (DJI RTK) with 45 degree angle.

I want to do simple measurements on the buildings in the images that i view in the webbapp. Is this possible?

If it is, do you have any workflow for this? Where do i begin?

I have arcgis pro advanced with image analyst and access to agisoft metashape and drone2map.

sorry I haven't had time to work with you on this.  We may need to set up a meeting to discuss details and your objectives (short term and long term).  

To start, I would need to be sure what "oblique viewer" you mean.  If you're building a Javascript 3x app using this widget ObliqueViewer | API Reference | ArcGIS API for JavaScript 3.33  and Web AppBuilder, note that the focus for the development team is JS 4 in the new Experience Builder.  So if this is something you need for long term, we should work in JS 4, but I don't believe an oblique viewer widget exists at this time. 

Another key issue is serving the imagery.  If you're seeking to use the image coordinate system (ICS) and share a mosaic dataset with the images using the frame camera raster type, you'll need ArcGIS Image Server.  (Perhaps you already know that?).

The mosaic dataset that you need is created directly in Drone2Map - the "dynamic mosaic" added in Drone2Map version 2.0 is configured for this purpose (e.g. to use on Image Server to access images using ICS, or to use locally in Pro for viewing in ICS or for stereo viewing with the Image Analyst extension).  Note you and I had a previous conversation (May 2019) about the sample script at http://esriurl.com/D2Mmanagement which will also create and configure a mosaic dataset, but as of v2.x this mosaic dataset is created by Drone2Map.

Could you send me an email to discuss?
