    Hi Götz

    the triangle signifies that the sensor used is not in the database.
    And we add there mostly just the "problematic" sensors.
    But I will prepare a short tutorial on how to add you sensor there

    Yellow triangle indicates a minor issue, we will add a tool tip which says what is wrong soon.

    To cast a more light into this one -

    focal.JPG


    If you can see 35mm equivalent in the image info (either 1ds or 2ds popup panel), then its OK. The yellow triangle is shown because there is a focal length w.r.t. chip size in the image EXIF/XMP but the chip size itself is neither in the EXIF/XMP nor in our database (sensorsdb.xml). However, EXIF/XMP contains 35mm equivalent and we can use it.

    We use 35mm equivalent as a soft prior during image registration/alignment. If the 35 mm focal is missing we simply do not use the prior. This may cause problems if there is a lack of depth in the image/planar scene or camera undergoes a critical/close to critical motion. Then the camera pose tend to be slightly off.

    If you do not see 35mm equivalent in our app but you have "focal length" in EXIF/XMP, then you can help app to calculate 35mm equivalent by adding a camera/lens model to our database. Select image in 1ds

    sensorsdb.JPG


    edit sensorsdb.xml (located where you have installed the app) and add a line with

    <camera model="NIKON CORPORATION NIKON D60" ccdWidth="23.6000" />

    between other cameras. Model is exactly what you see in 1Ds and ccdWidth is size of the chip in millimeters. You can search web for this easily. Save sensorsdb.xml and restart the app.

    If you made it right, you would see 35mm equivalent focal length and the yellow triangle should not be there.

    Thank you both for the quick replies!

    Since there is the right focal length (27mm) and camera name in the info box, I assume that everything is ok in my case.

    Does anyone have the ccdwidth for the Phantom 4 pro? I see a 1" cmos sensor, but I can't seem to find the actual width vs. diagonal...

    Hi,

    I added this " <camera model="NIKON CORPORATION NIKON D5000" ccdWidth="27.0" /> " to sensorsdb text, but it still gives me the error of the yellow triangle. Is there anything else that I can additionally do to avoid it? I am attaching a screenshot of my settings.


    Thank you in advance,

    Maria-Christina

    The sensor size for my Canon PowerShot A590 IS in sensorsdb.xml had ccdWidth="22.2" The sensor width is actually 5.744. Changing it to the correct value made a huge difference in the resulting model.

    Here's the link to the FAQ for editing the sensorsdb.xml  file:
