How do we start running cBathy and does it related to UAV tool Box?

[sivaiahborra]

Dear All, I have successfully done sample run in UAV Tool Box and could produce Timex, Bright and Dark images, I got stuck to proceed further to produce bathymetry by using cBathy tool box. I have a query that how UAV tool box is connected with cBathy tool box? I mean are the outputs of UAV will be used as input for cBathy like that? I got stuck there. Please anyone let me how to proceed further and how to run cBathy tool box? Thanking you.

I am having the same issue.

If you created a 'grid' pixel instrument during the UAV Toolbox collection, then there should be a .mat output timestack with the 'mBW' string in its filename. That is the timestack over the grid that cBathy uses as the signal to process. Other site-specific cBathy input should be modified in a file like argus02a.m Follow along some of the demo files to see how cBathy is used in context. E.g. cBathyDemoWithPlots.m

Good morning, Mr. Harrison. Thank you for your response. I have posted in the UAV Toolbox Forum as well about this issue:

I have been able to run the demoCbathy or either the cBathyDemoWithPlots. But at the time the analyzeSingleBathyRunNotCIL function is called I am having this type of error. For some reason, the sampleAerielleVideoDemoPIx script is calculating wrongly the first r.cam.xyz.

There is also another issue I am finding when using the UAV Toolbox: in the demoInputFile, if the xyCam and zCam are inputs in a real world coordinates, the algorithm does not work well for undistorting the UV coordinates.
