Is there a way to fine tune the radar beam width?

  • I tend to use partial (not 360') projections. Depending on the projection mode there is a better or poorer fit of the radar beam width / rotation rate with the associated pano. Tweaking the image parameters in the xml does some cotrection but at the expense of pano cropping.

    Is there any clean way to get this mapping tuned?

    cheers

  • Hi,

    an interesting request!
    normally the size of radar beam should be automatically correct...

    is the image hfov of "103" degree correct ?

    maybe try tweaking that value (the vfov don't need to be set, it will be calculated automatically)
    e.g.

    Code
    <image type="SPHERE" hfov="93" multires="true" tilesize="991" baseindex="0">

    best regards,
    Klaus

  • Thanks Klaus

    I had tried twiddling both the <view> and <image> parameters - but just succeeded in getting cropping or "blinds" at the edge of my image. But realised I needed to tweak both together and seem to have achieved an ok outcome. The Image angle I have been using has been determined by AutopanoGiga - and I have been assuming it was accurate based on its inputs from the EXIF lens info. Perhaps there is a bit of a drift, or perhaps I used a cylindrical mapping by mistake and the distortion happened there... (with krpano assuming spherical)

    THANK AGAIN!

    great product; I promote it whenever I get the chance.
