View Full Version : General Hardware Setup question - Sensors needed?

I have a general question regarding hardware setup.

Currently, I have a DMK 42BUC03 camera setup that takes video images of objects I wish to capture. However, the images I want to capture move pass the camera at a much higher rate than what the camera can reasonably pick up through video so I’m left with an image that cannot be imaged/read. The camera has a shutter speed that could match my speed requirements if the camera captures the image at the correct time the object passes the camera. Truthfully I don’t have the slightest clue what hardware/software/sensor applications I would need to look into to have the camera sync with this sensor so that the shutter can open and obtain an image that I could use for processing. Does Imaging Source have any solutions in place and if not where should I look?

Thanks,

Hello

If the objects move too fast, then a faster camera could help. The USB 3.0 camera DMK 23UP1300

http://www.theimagingsource.com/en_US/products/cameras/usb-cmos-ccd-mono/dmk23up1300/

is much faster than the DMK 41BUC03, it runs with 115 fps at the same resolution, see the following table:



Video format Norm Frame rates max, med, min
-------------------------------------------------------------------
RGB24 (16x16) 6968.641 3485.535 5
RGB24 (320x240) 1084.599 545.0186 5
RGB24 (640x480) 395.4601 200 5
RGB24 (1024x768) 181.3993 95.00014 5
RGB24 (1280x960) 122.8199 65.00007 5
RGB24 (1280x1024) 115.3043 60.00024 5
Y800 (16x16) 6968.641 3485.535 5

Y800 (1280x1024) 115.3043 60.00024 5
Y16 (16x16) 58.00027 30.00003 5
Y16 (320x240) 58.00027 30.00003 5
Y16 (640x480) 58.00027 30.00003 5
Y16 (1024x768) 58.00027 30.00003 5
Y16 (1280x960) 58.00027 30.00003 5
Y16 (1280x1024) 58.00027 30.00003 5


If you choose a 640x480 resolution, you will receive 395 images per second via USB 3.0. I think, this could be fast enough for you.

Hi Stefan,

I would prefer not to purchase another camera and lens unless imaging source offers returns for never-used cameras/lens? DM if so.

Are you aware of any hardware applications that would work in tandem with the camera to trigger the camera to open the lens when the hardware detects something passing by the FOV? Couldn't taking a still photo to image prevent the need to increase FPS on the camera if synced properly? Does such hardware exist?

thanks,

This depends on the point of time, when you purchased the camera.

Usuall light barriers are used for this. If the light beam is interrupted, an electronic generates a TTL trigger pulse, that triggers the camera to expose an image.
Your camera supports externak triggering.
Also it has global shutter, which is in your case very helpful. The other camera P1300 has a rolling shutter.

I would like to point out, the above listed frame rates of the DxK 23UP1300 are preliminary and are a subject to change for the release version of the DxK 23UP1300.
Also I was wrong about the rolling shutter: The P1300 has a global shutter.

I am very sorry for caused confusion.
