Inquiry Regarding Camera Positions and Distances in Nutrition 5K Dataset.

[umairharon]

In the dataset, there is a custom scanning rig utilized to capture videos, featuring four Raspberry Pi cameras labelled A, B, C, and D. We are inquiring about the specific locations of these cameras e.g. (x,y,z) and distances of each camera (A, B, C, D) from the object or centre of the rig where the plate or dish is placed.

We kindly request your assistance in providing this information or directing us to the relevant documentation where such details may be available.

Thank you for reaching out. If you take a look at Section 3.5 of the paper we published we have some details about the configuration and positioning of the cameras on the rig. https://arxiv.org/pdf/2103.03375.pdf I hope this helps. Best, Wade

Apologies for not making it clear, what I mean by my question is that I want to know the exact position of the camera in centimeters.
For example, I want to identify it in real-world camera coordinates such as X=1, Y=0.5, and Z=0. Can I have such information? AFAICT, I cannot find them in the mentioned sectioin.

Hi @wnorris,

Could we have the camera dimensions? I read section 3.5 and couldn't find the information I wanted. More briefly, I wanted to know the distances of the camera from the origin. I assume the overhead camera is the origin, and all side-angle cameras are points on a circle that is rounded in 360 in different degrees. Can you provide the information on the camera's full hand length?
