Choosing the right camera for my machine

[Rick (Technical Evangelist)]

I am sorry you feel as if we have not provided you with answers. I did a quick search to find that we have been engaging you here and have tried to provide you with responses to your inquires. First link returned this response we provided just 19 hrs ago:

Camera calibration

That camera is only 1920 x 1080. Assuming that it gives you the full resolution when capturing, the best possible accuracy you can hope for is about 1.5 to 2.0mm - you have about 1 camera pixel for each mm of your bed size, ideally you need two or more for 1mm precision or lower. If the image looks stretched in the middle or curved, it’s a fisheye lens.

and this as well, which clearly states: “A 170 degree camera is incredibly low resolution at the edges of the image because of the lens distortion. We don’t recommend using anything more than a 160.”

Best Camera Degree

actually I have same bed (1600mm × 1000m) and i have wide angle lens camera ( it’s probably 170 degree )… and same problem i don’t get perfect result and i don’t know ideal mounting distance this is my camera : https://www.amazon.com/gp/product/B00KA7WSSU

I also see several members have also chimed in with valuable information that addresses your questions. So I am confused,…

Let us try again because we do want you to have a satisfactory experience when using LightBurn or interacting with us directly.

Here is the information we provide to determine the best camera solutions for a given environment.

Use this to determine the best lens choice based on your mounting location.

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 …

And this might help in visualizing these choices.

Visual Guide for Cameras

As many of us are upgrading features on our lasers to include a camera, I thought I would share a guide to complement the math on the LB site. This is a visual guideline in comparison with the lid/bed, which includes brief print instructions in the file. The angles should be fairly close to spot on, but there may be some approximation, depending on your printer/settings. I placed it at the center of the lid in the open position and at the front of the bed to get an idea of coverage at both angle…

Once you have chosen a workable camera and lens choice, use this detailed video to setup and calibrate camera use within LightBurn.
