How to make DLP4710EVM-LC project a custom picture on a computer folder. I want to use a projector to achieve a 3D reconstruction of the fringe projection then I need to write a picture of the stripes into the projector

I have purchased DLP4710EVM-LC projector of your company, and I want to use it to carry out phase shift fringe + gray code projection for 3D reconstruction, but I don't know how to write the images in the folder into the

projector, make them projected in sequence and use external trigger of the camera

Hello Danilo,

Welcome back to the E2E forum.

I may not know the customer's project well. According to the description, they should be able to use internal pattern mode on the EVM to pre-load patterns in flash memory and a host command is sent to DLPC3479 controller to display the patterns. In internal pattern mode, they can use trigger in/out signals. Please note that the internal pattern mode only supports 1D patterns.

Please use the documents below for more information:

Please let us know if they have any further questions.

Lori

Hi Lori,

Thank you for your response. Please see the feedback of our customer below.

First of all, thank you for your help. I still met some problems in the operation process. As shown in the figure, I can project normally when I add a set of stripes, but when I add more than one set, the projection will appear as a flash. Do you know why?

Regards,

Danilo

Hi Danilo,

Does the failure occur whenever the pattern is not stripes? In other words, is the second set used here also a stripe pattern?

Hello Danilo,

What the firmware version are they using?

If they only display pattern set (2), can they display the stripe pattern normally?

Lori
