DLP2010EVM-LC: Outdoor metrology

Bruno Kempf

Part Number: DLP2010EVM-LC

Hi,

we would like to use the DLP2010EVM-LC for outdoor metrology where the light conditions are unconstant. The system moves from location to location whereas the effect of light changes. Is the DLP2010EVM-LC capable to provide a solid pattern for high-accuarcy metrology (height, width, depth)?

We were experimenting with more simple light sources but the changing of effect of light destroyed the pattern and did not allow high-accuracy metrology.

Also is there a recommended camera EVM for high-accuracy metrology / high-accuracy 3D scanning?

Best regards

Bruno

Hello Bruno,

Please see your other post where we address this question: e2e.ti.com/.../737970

Hi Kyle,

I deleted this post right after psoting it because it referenced the wrong EVM part number. I am unable to access this post. Sorry for the trouble :-/

Hi Kyle,

is there a way to reactivate the deleted post? Because I still have no access and therefore can't read your answer.

Best regards

Hello Bruno,

I apologize, I misunderstood what you meant when you said that post was deleted. Here is my answer below:

The DLP3010EVM-LC typically outputs 125 lumens while the DLP2010EVM-LC typically outputs 25 lumens. Obviously the 3010 provides more light and therefore may be more suitable. However, you may find that even more lumens are needed depending on your application, especially if you plan to have it project over a large area. This may only be suitable if projecting over a relatively small area if you are in direct sunlight.

While this EVM is designed with structured light applications in mind, we do not have suggested cameras or indications of how accurate you can make it. Any camera can be used that is able to be synchronized with the trigger signals output from the EVM. Additionally, accuracy will depend upon many factors such as your software, distance to the object, lighting conditions, etc. We do not have 3D scanning software, but we hope this EVM will be easy to integrate with your own code.

Thanks,
Kyle

Hi Kyle,

Seems like there is only one way to find out if it works outdoor. Try!

Thanks a lot Kyle!

Best regards
