Stereo Imagery - AT Project Format

BruceJohnson — Fri, 17 May 2019 13:57:24 GMT

I hope someone can offer me some guidance regarding stereo imagery in ArcGIS Pro. I am currently acquiring orthophotography of my county and after having seen an article about stereo mapping using Image Analyst, I asked the vendor if they could provide the aerial imagery formatted as stereo pairs. They are able to do that, but have asked me in which format I would like the ATed image frames. They can provide;

PAT-B
SummitEV
SSK/Intergraph
Inpho

I have no experience in this area, and having checked the documentation, have not found any answers. Can someone with some experience offer some help? The vendor indicated that they most commonly use PAT-B. Will that work with Image Analyst?

Thanks,

Bruce

Optimum is if you have a Aerial Triangulation project file that provides, the interior and exterior orientation parameters as well as the camera calibration. PAT-B format only provides the exterior orientation. ArcGIS has a Raster type specifically for Match-AT (Inpho) and ISAT (SSK/Intergraph). I would recommend going with the Match-AT/Info option if your vendor provides. Then you only need to create a mosaic dataset and use the Match-AT raster type. You will probably need to do a search/replace on the filenames in the provided .prj file. Also consider optimizing the format of the imagery by using say OptimizeRasters (output as TIF) to ensure best performance.

Thanks very much Peter. Exactly the information I needed.

Hi!

I'm trying to do stereo models with "ortho mapping workspace" workflow.

I have the Match-AT (inpho) project file and my overlapped images.

I put in my project file in the project file field but what is the camera file? Do i have to create one or do i need to ask my provider for it?

Regards Mattias

Mattias,

Match-AT, older Versions, have CAMERA files with them - my data in same Folder as *.prj file ... in newer versions (5+) camera information seems to be included in the prj file.

if you have Match-AT files, you would not need to start your workflow in the OrthoMapping part (your screenshot) ... you could just create a MosaicDataset, add your data using the Raster Type "Match-AT" (and ideally specifying a DEM with it) - see this description Match-AT workflows: https://pro.arcgis.com/en/pro-app/help/data/imagery/aerial-imagery-raster-types.htm#GUID-C17727AB-D9A6-408D-8A26-0F7CD01E7551... then you could enter the OrthoMapping Workflow with the " Import and use existing image collection" check box on the first screen.
BTW: Make sure that the paths to the images in your Match-AT project file are correct!

Regards
Guenter

Just to add. Note the DEM if provided just provides a better base. It is not needed to see stereo. If you provide the DTM (or constant elevation) then when you open the mosaic dataset and zoom in you should be able to see the imagery rectified to the ground in approx the correct location. This is a good way to ensure the coordinate system etc is correct. Also you do not need to use the OrthoMapping workflow. Just use the Build Stereo Model Tool. This is required to define the stereo models. In it you can also define parameters so as to limit the stereo models to only the forward overlap if required. Once the stereomodel table is created you can open the mosaic dataset in the stereo tool and the stereo models will become accessible.

Thanks for all the help. It now works perfectly

Question for all of you, i have stereoscopic aerial photographs from 1938. Any recommendations on where i can scan them. I'm located in Southern California. Thanks.

Hi Mattias,

Is it possible to give me a short summary about your worflow to import a stereo-model of Match-AT (Inpho)?

Thanks, Abiy

Hola a todos. Necesito crear el dataset de raster para realizar una fotointerpretación con el Stereo, pero no sé cómo hacerlo. Podrían ayudarme?

Por favor, perdone mi mal español. Usé https://translate.google.com/.

Solicitaste ayuda para crear el "conjunto de datos ráster", pero creo que te refieres al "conjunto de datos en mosaico". El dataset de mosaico es una estructura de datos específica en ArcGIS para acceder a imágenes y se utiliza para administrar imágenes para visualización estéreo. El dataset de mosaico se crea dentro de una geodatabase y se vincula a las imágenes de origen. Las imágenes de origen no tienen que estar dentro de la geodatabase.

Puede comenzar aquí con respecto a cómo crear el conjunto de datos de mosaico https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/creating-a-mosaic-dataset-pro-.htm y tenga en cuenta Tendrá que utilizar el "Tipo de ráster" adecuado para agregar imágenes junto con datos de orientación para habilitar la capacidad de visualización estéreo.

Si está utilizando imágenes de satélite, el tipo de ráster tendrá el nombre del satélite. Si está utilizando imágenes de una cámara digital, el tipo de ráster debe aparecer aquí https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/aerial-imagery-raster-types.htm

Si está utilizando imágenes de drones o películas históricas escaneadas, háganoslo saber y le podremos asesorar más.

Cuando tenga un dataset de mosaico configurado correctamente, puede calcular pares de imágenes para visualización estéreo usando esta ayuda https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/build-stereo- modelo.htm

Hello Cody,

I tell you that I am working with aerial photographs for a photointerpretation, and I have already created the mosaic, but I cannot yet use it for the stereo.

This is where I am stopped and I cannot move forward because I do not know how to construct the stereo model to begin the photointerpretation.

In ArcMAP there is an extension called stereo analysis, where the photogrammetric block can be imported to be used

so those are the ".blk (LPS)" file types that I need to make but in ArcGIS Pro

LPS has the ability to export the BLK project to either MATCH-AT format or SOCET format. Please export to MATCH_AT. Once exported you may need to update the image paths in the *.prj. Following that you are able to import the MATCH_AT project in Pro using the workflow found at https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/aerial-imagery-raster-types.htm#GUID-C17727AB-D9A6-408D-8A26-0F7CD01E7551. I hope this helps. If not please send me an email at cpatterson@esri.com.

Hello, I tell you that I could not do it the way you indicated, since LPS does not allow me to export to MATCH-AT format.
I created the data set mosaic, now I want to know how to build the stereo model. Greetings
