@5aou Maybe it's a little late now about your question as you may have purchased one, but i think ueye camera is a good choice.

@jingpang ,
I also have the similar camera model, which is iDS UI-1221LE
http://en.ids-imaging.com/store/ui-1221le.html

But I came across the following issue.
When it is used in outdoor scenario, it suffers from overexposure issue, in which I only see the plain white screen under daylight. But it is OK when it is used in indoor scenario under moderate lights.

Did you come across this issue when you use iDS monocular camera? And how do you handle it?

THX~

^ Which Logitech camera are you using? I have gotten decent indoor results with Logitech c310 and c920. It has been answered before that it's recommended to use a global shutter camera with a wide angle lens, see #24.

However it is possible to get decent results with a consumer grade web camera as well. Be sure to calibrate it correctly (http://wiki.ros.org/camera_calibration). It is important to calibrate in a well lit room as low light rooms might cause the blurry images. The TUM RGB-D datasets are all recorded on Kinect and Asus Xtion cameras, where the RGB part is nothing better than most affordable web cameras.

While it might be worth it to invest in a more expensive camera unit, I would advise you to make sure that your system is running correctly first.

thank you for you response,I'm using a Logitech QuickCam S5500, I managed to calibrate it by installing "ros-indigo-usb-cam"' , but I cant resolve the last problem (Fixed Frame No tf data. Actual error: Fixed Frame [ORB_SLAM/Camera] does not exist) mentioned at #42 , do you have some suggestions ?

from orb_slam.

OK. I don't think that's a good camera, but you should be able to get some results that at least makes some kind of sense. Also see my answer which I will give you in #42 now

@amiltonwong ,
You can try auto exposure instead of fixed.

I use the ueye_cam package to read frames.
(sudo apt-get install ros-indigo-ueye-cam , see 'http://wiki.ros.org/ueye_cam' )

Below is my ros launch file in which the exposure and other modes can be configured.
