D455 RGB Color Problem

Follow
Silvio Foschi

I recently bought 2 D455s but they both have problems with the RGB sensor with daylight, I am attaching some images to better understand, how can I solve this problem? the cameras are new and with updated firmware

 

while indoor it seems to behave correctly

There are configuration problems?

Regards

    Hi Silvio Foschi  This is a known issue with the D455 that Intel have investigated.  The Chief Technical Officer for the RealSense Group at Intel (agrunnet) provides information about it in the link below.

    Hi, I have the same issue with my newly purchased D455 as shown below, and wonder how to resolve it. Can I get a replacement or get it repaired?

    Hi Hanme Kim. This is not a fault or bug and the D455 does not need to be returned.  I will refer your case to a member of Intel who can provide specialist advice about this issue.

    Hi again Hanme Kim   Due to the sensitivity of the high quality D455 RGB global shutter sensor, there are extreme corner cases where the RGB image may have a hue or have reddish colors.  Intel believes this is a rare corner case and most customers and use cases will not see this issue.

    For customers who wish to utilize the D455 in extremely bright sun light then Intel suggests the option of attaching a Neutral Density Filter just over the RGB camera.  More details on filters and their usage with RealSense products can be found here:

    I'm sorry but I disagree with these reasons, I bought 2 cameras that show the indication that they can be used outdoor, for our project we should have used these cameras outdoor. By purchasing a new product I expect that this has been tested and optimized also for outdoor use and I would have expected from Intel a resolution to the problems without incurring costs, therefore I would have expected that the filter will be provided to me directly by Intel for the resolution

    Hi, I'm suffering from the same issue when I'm trying to reconstruct HDR RGB images in indoor scenes using my new D455 Camera. The first several images with low exposure time clearly have reddish area around the lower right corner. And I found that the reddish area occurs every time I set the exposure time to lower than 1ms. I don't like to use a Neutral Density Filter because that will increase the exposure time of high exposure time images. Is there a better way to solve this problem, like updating the Firmware? Or will D435i do better with low exposure time?

    Hi!

    I have the same problem and let me elaborate on this issue.

    I'm founder of a multispectral camera company and we had this exact issue with some filter producers back in 2017. Their filters advertised as "stabldge" (you can search the name of the company) but in reality their products weren't. I'm 100% sure Intel using the same filters to block out the NIR because it has the same problem. The NIR light bleeds through horizontal-vertical edge of the filter and causes this problem.

     

    This is a production issue and intel must recall and replace all of the affected units like we had to.

    Intel; You can't solve this issue with firmware update.

    I'm returning my D455 and I'll advise my customers NOT to buy them.

    Regards

    Hello,

    we were testing several 3D-sensor-devices (PMD, Stereo, LiDAR) including the D435 and D455. The D455 in particular aroused our interest, as it was explicitly advertised for outdoor use (!). We are satisfied with the 3D result of the camera, but the color distortion, which also appends on cloudy days, really disappoints us! I have read your article about using a ND-filter, but that sounds to me like an ugly hack.
    The least I expect from Intel is that this filter, including the holder, is provided free of charge. Or are there already replacement cameras that have been optimized in this respect? 

    Best regards

    FYI, I tried a ND filter as shown below. Beside extra $50.45 (a ND filter inc. shipping) and its ugly looking, I found that can't be a solution at least in my case (a moving platform). Basically, it increases the exposure time eliminating the color issue, but consequently it becomes easier to get motion blur. I bought a D435i instead to give it a try, but not sure yet because of its rolling shutter (RGB). Definitely, I wouldn't recommend D455 for outdoors.
