How to select Camera Field of view

[xerotolerant (Kheenan Walkins)]

What is the calculation that I need to use for deciding which camera FOV to select on checkout?

I am setting up a 1500mm x 1000mm work surface. The camera will be in a fixed position above the work surface and not on a movable cover.

I swear I saw the calculation before somewhere on the official light burn website.

Would the image be improved by adding some strip LEDs to the door to increase the light intensity and uniformity on the bed and material?

Quick Tip - Best place to mount a USB camera to use with Lightburn?

We get asked this a lot. Straight down, in a stable location above the bed, with the whole bed in view, with a little extra room to allow for pixel loss when correcting distortion is “best”. If your lid opens to a set and consistent location, mounting with the lid open works well for clearance and reduces the requirement for extreme fisheye. With a well focused and calibrated camera, it is possible to correct an awful lot, but extreme angles or extreme fisheye will test the limits of it. Mount…

Lightburn Camera Calculator

I whipped up a Lightburn Camera Calculator to help determine which camera focal length might be appropriate for any given machine. Give it a whirl & let me know if you see any issues! I hope this helps everyone answer the question, “Which camera do I need?” https://tinyurl.com/LightburnCamera [LightBurn%20Camera%20Calculator%20Screenshot]

What is the best camera lens to choose for my bed size?

To answer this question requires one additional piece of information: The height above the bed that you plan to mount the camera. LightBurn now has a helper that will do the ugly math for you. Go to Help > Camera Selection Help and the software will use the current workspace size by default, and show you the minimum mounting heights for all the cameras we sell: [image] This number is the absolute minimum required for the camera to see the whole working area. You will need to allow a little …

We have learned along the way, and now have a built-in helper tool in LightBurn to assist as @fred_dot_u identifies.
