Which RealSense product is right for me? D455 or L515?
Hi,
In https://support.intelrealsense.com/hc/en-us/community/posts/360051746714-Which-RealSense-product-is-right-for-me- I asked which RealSense product is right for me and MartyG kindly replied that amongst the D4xx series, his view was that the D455 was an excellent fit for my application.
Now, my question is, what are the pros and cons of the D455 vs the L515? Which of those two models would be the best fit for my application?
To recap my application from the previous post, I want to surface map hand or face geometry from between 2 and 8 devices from 3-5 metres away from the object, at HD resolution, at 30 frames per second or better. The cameras will be fixed-position. The actor will be relatively stationary (generally standing rather than walking or running).
I will be combining the data from the devices using something like PatchMatch multi-view stereo [Galliani et al. 2015] or our own algorithm working along similar lines.
The devices will be used indoors in a green screen film studio with controlled, diffuse lighting.
I am aware of this Intel white paper: https://www.intelrealsense.com/download/13722/?_ga=2.51045933.524337036.1610892839-1069553977.1610746190
Would the D455 or the L515 be best suited to this task?

Hello Michael,
Update: I just noticed you want HD depth resolution. The L515 does not offer 1280x720 depth resolution. The highest depth resolution available for the L515 is 1024x768.
The D455 offers 1280x720 depth resolution.
I recommend you read this paper before you decide: https://www.intelrealsense.com/which-device-is-right-for-you/
Both cameras may work for you. The L515 is very sensitive to ambient light so it works better with less light. If lighting is minimal, then the L515 may give you better fidelity at those distances.
I recommend purchasing a couple of units of each type of camera and testing them. The code-base is the same.
Sincerely,

@... many thanks for your reply.
We want to use the camera in an environment where we are controlling the lighting. We are using a mixture of LED and fluorescent lighting - the area will be well lit but we can carefully grade the lighting to minimise the presence of light sources at 860nm by placing IR cut-off filters over each light source. There won't be any natural light on the scene.
Am I correct in thinking that the L515 sensor is very sensitive to light at 860nm but any light hitting the sensor that is from the visible band or UV frequencies, shouldn't cause any problems?
