Best software for going from scene to orthophotos

Post by Wannascan » Sun Mar 12, 2017 8:24 pm

What is the best software solution for going from scene to orthophotos? I am looking at PointCab since it seems to be geared for this in particular. Are there any other more efficient solutions?
I have a project due asap that requires 1-2 hundred orthos.


Thanks

The SCENE APP does that.

I sometimes use JING a free PC program to click and drag a portion of the screen I want. It creates a. Png file. The size of the image is dependent on the screen pixels selected in the click and drag box you selected.
I have a 4X screen and set the view in SCENE to Ortho view.

You may want something more accurate depending on your screen and graphic card settings. Check the results you get. Mine are good enough for what I need and they look better that what the SCENE app makes.

I need something accurate as it will be used by architect that doesn't want to learn how to use pt cloud.

Scene, although you can edit the amnt of pixels to make it look better, takes 10 minutes or so to make one ortho and in the Pointcab demo it can be done in around a minute.

I can see how architects would want just orthos if they just want something simple and light on their systems. Of course I would prefer to just sell pt clouds but that is not the case :|

I suggest you give my method above described a try and just compare it for accuracy against the ortho SCENE makes. JING take just a few seconds to get a very good looking ortho image. If you have hundreds to make you will be done before lunch!

Good topic.
I have a license to Scene and PointCab, but work with Scene more regularly due to its better image clarity.

Architects routinely use ortho-images for 2D plans, elevations, sections, and section-elevations. With BIM we have the ability to extract these ortho-images, as needed, from the 3D solid models (as they are from point clouds). With a good clipping box, one can cut a plane vertically, horizontally etc. to isolate views of interest. Even a good clipping box can't do a segmented section cut, however. We have 2D section markers to indicate complex sections, but no easy way to create them from our point cloud models, unless they are first brought into CAD or BIM platforms. Nor can we easily create vectorized polyline outlines of plans, elevations, sections, and section-elevations from our orthophotos. Tracing certainly works, but it is inaccurate, time consuming, and just plain tedious. With vectorized polylines, one has the ability to snap to corners, centerlines, and midpoints for smart dimension chains etc. Working with rasters from .jpeg, .tiff, and .png images is sloppy -that's why we have better tools in CAD/BIM platforms. That said, I'd still like to have great annotation tools within Scene (it has the nicest images) to easily generate 2D documents from the point cloud used in the background. Text, symbols, and dimension chains are just as important as the image one is looking at. It's all a complicated business, so I'm sympathetic as to why the scanning and AEC software has been historically separated. We all have our wish lists...

Hi William,

SCENE WebShare Cloud also has a functionality to create Orthophotos. Since they are generated on a compute cluster, the number of scans and the scale (detail level) are almost unlimited.
For a description, refer to the user manual:
http://manuals.faro.com/documentation/f ... orthophoto

Some examples: Best regards
Martin
