How to use known Projection Matrices of cameras to generate new fundamental matrix located correctly in 3D space?

I have a few cameras which have been calibrated (using a checkerboard) so I know the fundamental matrix between an origin camera and each remaining camera

I wish to take pairs of camera with no fundamental matrix – but each has a projection matrix – and calculate the fundamental matrix with the view to reconstruct the stereo pair in 3D. To clarify – as all cameras have a projection matrix – I should be able to take any combination and generate a Fundamental matrix – so I can reconstruct and combine stereo pairs in 3D using as many pairs as possible

currently I use this formula: enter image description here

(decomposing Projection matrices from camera to get C)

but that didn’t quite work with stereo pairs that don’t include the origin. I noticed that to calculate the fundamental matrix that rotation was relative so I added the relative rotation formula when recalculating P from K/R/T (intrinsic camera params, Rotation matrix, Translation matrix)

enter image description here

but now each reconstruction appears on the camera position (I think) instead of all stereo pairs being mapped into same space to give a dense reconstruction

Does anyone know what I am doing wrong? thanks for any help

How to set a variable to all the numbers located in a list?

Lets say I have a variable set to this:

set myVar to {"asdf", "qwerty24", "23", "22", "21abc" "20"} 

How can I set a variable to the numbers in myVar, including those with text inside of the item–but without keeping the part that is text. Each item should only contain one number, if an item were to consist of multiple numbers ie “302 303” then the outputted result would preferably be just combined to “302303”. Any spaces in the item need to be removed to, just like the text. If each number needs to be an integer so “0abc.1200” needs to have it’s period removed and result with “1200”. The result would be preferably listed as {“24”, “23”, “22”, “21”, “20”}, instead of being listed as {24, 23, 22, 21, 20}.

Exchange web services Error – The Autodiscover service couldn’t be located

I am using Exchange Web Services(EWS) to create outlook meeting invite in SharePoint Visual Web Part. Following is the code snippet to get the instance of EWS.

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013); service.UseDefaultCredentials = true; service.AutodiscoverUrl("firstName.Lastname@xxxxxxxx.com", RedirectionUrlValidationCallback); 

When I use it in test console application, it is working properly. But if I use it in Visual Web Part on same server with same user account, then it gives following error.

Microsoft.Exchange.WebServices.Data.AutodiscoverLocalException: The Autodiscover service couldn’t be located. at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.InternalGetLegacyUserSettings[TSettings](String emailAddress, List`1 redirectionEmailAddresses, Int32& currentHop) at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.GetLegacyUserSettings[TSettings](String emailAddress) at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.InternalGetLegacyUserSettings(String emailAddress, List`1 requestedSettings) at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.GetUserSettings(String userSmtpAddress, UserSettingName[] userSettingNames) at Microsoft.Exchange.WebServices.Data.ExchangeService.GetAutodiscoverUrl(String emailAddress, ExchangeVersion requestedServerVersion, AutodiscoverRedirectionUrlValidationCallback validateRedirectionUrlCallback) at Microsoft.Exchange.WebServices.Data.ExchangeService.AutodiscoverUrl(String emailAddress, AutodiscoverRedirectionUrlValidationCallback validateRedirectionUrlCallback)
