    Hi jss

    play with the settings a bit as there is not precise guideline as the settings depend on per project data.

    Change their "weight" form default X=1 Y=1 Z=0,8 and change them in steps up to X=100 Y=100 Z=100 recommend to go with at least 2-3 steps. when you finish step 2, remove the first alignment COMPONENT so only latest COMPONENT is in the project and do this after every step. Make incremental project save, so can inspect the results later.

    i need to know what exactly you are saying - i have to adjust the values for each project even if i am using the same equipment

    this makes no sense - can you explain what these values are and how they work - i saw in another post that gcps have a value of 10 for each - is that because the gcps are considered accurately located - and if this is the case and the drone camera is also accurately located then a value of 10 is appropriate

     

    thanks

    Hello,

    I'm doing some work with underwater images and I'm getting a banana effect on the solution. I have INS data, which should be in the cm range for X,Y,Z and tilt values that should be within 5 degrees. I've loaded these flightlogs in and it looks like the settings may have changed slightly since they were discussed in this thread. I have some questions regarding Camera Prior Settings:

    Position X accuracy - this states that it is measured in the coordinate system value, so is it the accuracy in meters (less being more accurate) or is it a weighted value (higher = more accurate)?

    Position Prior Hardness - is there a value in which the program will take these values as absolute?

    When I run the process with an extremely high Camera Prior Hardness, I still see the orange lines vary from the supplied locations, why does this happen?

    Which accuracy does the program use if you give accuracies in the flightlog import menu as well as the camera prior settings?

    If I have pre-existing components and align again, will the program use positions of the old components, or will it start from scratch? I ask because I'm trying to compare results to determine what each setting does and although I see some variation, it isn't what I would expect.
