Problem with usb Light microscope for capturing images

[zahidkjatoi]

Hello All,

I want to connect small Usb 2.0 microscope with Labview. It is a cheap one, 5MP USB Microscope 20x-300x Digital microscope. The goal is to take pictures automatically after some time duration.

In its specifications, Directshow is not mentioned. It does not provide any api for labview. It has its own software which can show images and video. The software is MicroCapture Pro. can be downloaded from http://www.mustcam.com/download/MicroCapture-Pro-Windows.exe. It has opencv_ffmpeg dll file which is not usable as i don't know the commands. There is an open source dll from  https://ffmpeg.zeranoe.com/builds/ .  I can run ffmpeg with ' system Exe vi ' but the i could not really get any image. I am not sure whether this works with hardware or not. I don't want to capture, edit or manuplate videos as ffmpeg works for video format. I just need to see and save images.

Can anyone guide me how to solve this issue.

Thanks in advance.

Hello zahidkjatoi,

have you seen this side

FFMPEG scripting in LabVIEW (.NET)

there are examples for doing this with LabVIEW and your DLL (assembly). You can acquire a avi and then extract the picture from them.

So why LabVIEW if you are not using it to capture or manipulate the images?  I presume you are using LabVIEW to do something with your microscope, and want to integrate Image viewing (and possibly acquisition?) with whatever LabVIEW is doing for you.

Does your Camera show up in MAX?  [I should have first asked if you have installed the Vision Acquisition Toolkit and IMAQ drivers in your LabVIEW installation].  Getting LabVIEW to show images and save them to AVIs is not difficult (providing you have the drivers and Toolkit/Modules].
