Re: SLS on a budget - camera and lens choice

Alright... I made myself some panels using din A4 cardboard with printed markers and some wooden panels. Calibration worked right away. Then i went on to make a first testscan... I sacrificed my trusty rubberduck for the cause and this is the result. 30 Scans (360° loop) were made on a single height...

Re: SLS on a budget - camera and lens choice

I thought i'd keep you guys updated... My parts from china finally arrived. I went with OBNRacers recommendation and bought the 12mm ZLKC lens which fits nicely with the YW500U3 camera. The FOV is also perfect. The setup works so far, but i now need calibration plates. I printed them on cardboard as...

Re: Does david support GigE interface camera?

Greetings. Afaik it doesn't out of the box. GigE is a proprietary standard used by different manufacturers across the industry. However, if the cameras software supports an output format which David can make use of, then it might work. David should be able to recognize any camera which behaves like ...

Re: SLS on a budget - camera and lens choice

I went further and modelled all parts and viewing angles in CAD as i'll need that anyways for my mounting brackets. Here's what it looks like with 1/2.5" sensor (YW500U3) and 12mm lens (ZLKC HM1214MP5). The blue rectangle is the FOV of the camera (~1150mm distance to object) and the yellow one is th...

Re: SLS on a budget - camera and lens choice

Thanks for your response. I'm aware that usually the focal length is stated for a certain sensor size, i'm also familiar with the crop-factor on regular photocameras. Luckily ZLKC states the FOV of their lenses for different sensor sizes which makes it a lot easier to calculate everything. Here's wh...

SLS on a budget - camera and lens choice

Greetings all, i'm a long time lurker on this (and the "old") forums, but never managed to register. I'm currently in the process to build myself an extremely low-buget SLS scanner (~300 bucks). I've read a lot of posts on here and noted that OBNracer uses a low-budget 5mp C-mount camera and lens. T...
