Point Cloud in view port flickers and disapears

[Bryan3D]

After i do the Align Photos my viewport is blank. If i rotate the control sphere every once and awhile i will see the point cloud flicker in and out. It is pretty much impossible to actually view the point cloud and rotate around it. Ive also added a screen shot of my camera cal settings. Is this a legit setting?

Disregard, I figured it out. I believe the camera on my LG G2 does not give the EXIF info. I'm a total newb to this but im pretty sure thats the issue. I was able to use the wifes camera on her phone with no issue.

Bryan,  Don't mind if I chime in do you?

I don't think EXIF is critical.  I have shot aerial movies, converted them to  TIFF sequences (and in the process stripped out all the EXIF data) and had the model come out beautifully.

I am familiar with the phenomena you are describing however.  In my experience, it comes from Photoscan attempting to build a model from your entire shot, inclusive of everything behind the object.  So you get this point cloud that is super-deep and you are stuck in the middle of it.  As you rotate around, it comes into view and then quickly disappears again.  I hope this is making sense.  Why your project works with your wife's camera is a mystery to me.

Are you masking your images?  I bet if you took your original set and just drew a very loose marquee around the subject that you are trying to model that you'd get much better results.  Believe it or not, the mask does NOT have to be accurate.  Like I said, just draw a box around the subject and see how that goes.

Hello Bryan3D,

According to the "symptoms" and the information that can be seen on the screenshots I assume that the problem is related to the built-in GPS unit that writes coordinate information directly to the image EXIF. PhotoScan loads the coordinates by default from EXIF to the Reference pane and then use this data for the model referencing and scaling. If the object is rather small and the measurement accuracy in low, you'll likely have exactly the same coordinates for all the camera positions.
If it is the case, then do the following: clear the contents of the Reference pane for camera coordinates, switch to the Local Coordinates in the Reference pane settings, Reset transform from the context menu for the active chunk (after right-clicking on the chunk's label in the Workspace pane).

Boom! Thanks dude.
