D405 as a stereo camera
Hello,
I am looking to use the D405 as a stereo camera for facial capture to be processed with Unreal Engine 5. I can not make use of the depth tracking hardware with this software, I will only be using a stereo pair of images.
Am I correct in thinking what this camera outputs is two 16bit monochromatic images, that at 720p can record at a maximum of 30fps.
The camera will be mounted to a facerig, so will be at about 30cm from the face which seems to be optimum for this camera.
The camera is inobtrusive and that is what has attracted me to it for this purpose. Do you think that this is the most suitable one ion the range?
Many thanks,
Josh

Hi Josh The D405 camera model can output high quality depth, infrared and RGB color images at 1280x720 (720p) and 30 FPS. The monochrome images (the ones that you plan to use) are infrared, and the camera can provide a pair of left and right infrared images. The 16-bit depth stream is the blue one below.
The ideal depth sensing range of the D405 model is 7 cm to 50 cm. This distance limitation does not apply to the left and right infrared images though, so the distance of the camera from the face will not matter.
In regards to which RealSense model will be the most suitable, the D405 model is not equipped with an infrared projector component. So if you anticipate that the camera may be used in low-light or dark locations and the depth image is not going to be used, the D435 or the D455 (which has a wider field of view than D435 and can see more of the scene) would be suitable. If your scene will be well illuminated though then the D405 will be an appropriate choice.
