No camera output

The O3D311 is a stainless steel version of the O3D301 (40 deg opening angle). The 301 and 303 differ only in opening angle. We should see no data difference between all of these articles.

@aswinhope I apologize for the confusion. All articles in the O3D3 series have the ability to view both depth and amplitude data.

Articles ending in a "0" or "2" are considered sensors and work directly with the ifm Vision Assistant. An example is O3D302.

Articles ending in a "1" or "3" are considered cameras. These are designed to be used in conjunction with ROS, Halcon or with the ifm SDK.

I hope this helps.

I'm going to assume the O3D311 resembles the O3D303 enough that the info below applies...

It looks like you are looking at the "Raw Amplitude" image which could be difficult to interpret. Turn on the "Amplitude" image (in rviz), which is actually the "Normalized Amplitude" image. This will look more like an image from a grayscale camera as you would expect.

Thank you Tom, but the Amplitude image shows the same thing. I guess I have the wrong camera. Its really hard to find the difference between the 30x and 31x models in datasheet. As recommended, will try to get a 303 model and try it out

A few other things...

You don't necessarily want to update to the latest firmware, but rather run a supported software stack (i.e., IFM Firmware + libo3d3xx + o3d3xx-ros). The project README files have a matrix that lays this all out.

You may want to play with your imager settings to get a better picture. There are various permutations of number of frequencies, number of exposure, exposure times (short and long), etc. You likely just need to play with those settings to get something usable.

Finally, be mindful of what you are trying to image -- surface material, reflectance properties, distance to it, etc. Take a look at the "Good Bad Pixels" image. This is a binary image that will show you the count (and spatial location) of good vs bad pixels.

Hmm. Ok will give it a go again 2moro. Im hoping its just out of focus. Thanks guys

@aswinhope what scene you are looking at? Your image looks really strange. I recommend mounting the camera looking at the ceiling in ~2m distance in this set-up you can use your hand to check the sharpness of the camera. The recommended way is to double check the camera with the ifm Vision Assistant.

Hi,
I wasnt able to view the camera output in ifmVisionAssistant. I chose both 2D and 3D options, but I saw nothing like a grayscale image

Dont know how true this is, but I was just told by an ifm sales person that the 313 cannot view image
