For more information on the procedure of "Extending Camera Database" see the respective Help section built in your RC. a yellow question mark appears in the 1Ds panel next to an image when the system has incomplete camera information.Īdd a new line to the sensorsdb.xml file with the camera model name, focal length (and camera distortion). adding priors helps registering images more precisely lens distortion is directly noticeable in input images your image files contain focal length other than 35mm equivalent, with respect to its chip size If a camera stores the 35 mm equivalent focal length into an image file, RC will read it from there. It is not necessary to add every camera to the database. Then the camera pose tends to be slightly off.ĭo I need to add my camera information into the database? This may cause problems if there is a lack of depth in the image/planar scene or camera undergoes a critical/close to a critical motion. If the 35 mm focal is missing, it simply does not use the prior. RC uses a 35mm equivalent as a soft prior during image registration/alignment. Adding this information will remove the yellow triangle. In case you do not see the 35mm equivalent there and you have the "focal length" in EXIF/XMP, then you can help RC to calculate the 35mm equivalent by adding a camera/lens model into its database. If you can see a 35mm equivalent in the image info (either in the 1Ds or 2Ds panel), then it is all right. It means that your camera (objective/chip size) has not been added to the software's database yet, which is a minor issue. Yellow triangle with an exclamation mark in it in my image list in the 1Ds panel. UPDATE: automatic sensorsdb.xml update since version 1.: Version 1.
