Software unlocks the full potential of 3D scanning applications


 A big part of my job at TI is speaking to customers about their design needs related to DLP® technology and then connecting them with the right tools to get them started. As a result of meeting with so many diverse customers, I can identify key areas of technical content and support that we can focus on to make the design process easier, and hopefully faster.

Most engineers immediately think of the physical digital mirror device (DMD) and hardware design needs when first considering DLP technology. But, another area that is fundamental to ensuring a successful experience for our customers is software tools. That’s where our software development kits (SDK) address a key need.

Our new DLP Advanced Light Control SDK for LightCrafter™ series controllers gives designers the ability to develop their own code using intuitive APIs and integrate DLP technology into their designs. By using this SDK, engineers can start software development faster and implement advanced pattern modes when working across DLP platforms.

We initially designed this SDK to be focused on a particular method of structured light 3D scanning that uses Gray-coded binary patterns and a global shutter monochrome camera. Through speaking with designers in the field and on the TI E2E™ forums, there was a demand to expand on the initial SDK offering. We’ve made several enhancements based on this feedback.

Here are just a few highlights:

Sinusoidal scanning: In addition to binary scanning, this SDK adds hybrid sinusoidal pattern scanning. Sinusoidal patterns can improve the accuracy of point cloud results and offer a way to reduce the required pattern set, which can increase the speed of a 3D scanning application.

Rolling shutter control: While we have previously supported a Point Grey global shutter camera solution, the updated SDK adds support for a rolling shutter and a generic OpenCV camera option. The addition of OpenCV camera interface support greatly increases the number of compatible cameras that can be evaluated, thus helping during system development and optimization.

Compatibility across multiple DLP chips: Users can more easily migrate their application design across multiple DLP technology platforms. In addition to the DLP LightCrafter4500, this new SDK supports the DLP LightCrafter and DLP LightCrafter6500. In other words, customers can scale their solution from small form factor WVGA to larger, brighter 1080p resolution.  

I’m excited to see this modular approach provide developers with the flexibility to adapt pieces of functionality instead of building something from the ground up each time. Our vision is simple – it’s all about making it easier for developers to get started on whatever designs they have in mind.
