Custom tracking algorithm

[Matty]

Hello,

I want to use sharpcap to capture and track on custom features, for example fit a circle and track that (for solar limb tracking).
Is there anywhere an example for both parts, fetching a frame while recording, and send tracking commands back to the mount?

I have the algorithm already ready (tested in post-processing after capturing).

Kind regards,
Matthias

Hi,

you can get notified of each frame like this

Code: Select all

def Handler(*args)
	bitmap = args[1].Frame.GetFrameBitmap()
	// do stuff with the bitmap
	bitmap.Dispose()

// register for the event
SharpCap.SelectedCamera.BeforeFrameDisplay += Handler


// unregister later
SharpCap.SelectedCamera.BeforeFrameDisplay -= Handler

You can also move the mount - like this

Code: Select all

// the parameters match the ASCOM MoveAxis call - https://ascom-standards.org/Help/Developer/html/M_ASCOM_DriverAccess_Telescope_MoveAxis.htm
SharpCap.Mounts.SelectedMount.MoveAxis(axis, rate)

Hope this helps, Robin

Hello Robin,
yes, that will help, thank you!
I'm basically trying to implement limb/circle tracking, for example for solar photography with high gain/exposure time (i.e. solar disk is white, and (currently) you only have very few features on the limb), because in this case feature tracking likes to track on noise.

Other question, is there some kind of official Sharpcap-Repository?

Kind regards,
Matty

Hi,

No, sadly no official place to put script snippets and samples except for in the forums here.


Cheers, Robin
