DLS-1 Module - Exactly Synchronized Frames by One Single Electronics
ViALUX Scanning Modules
The DLS‑1 Module is equipped with one DLP® projection and one image sensor that can be slightly tilted to adjust the working distance in the range 1 300 - 3 000 mm. The distance between projection lens and imaging lens is 410 mm.
System Architecture
The DLS-1 Module schematic shows the architecture with the main data flow. The ViALUX FPGA logic controls both, the high‑performance DLP® chip for fast and accurate pattern projection and the image sensors for digital imaging. In that way pattern generation and image recording are precisely synchronized, also for partial sensor readout in a region of interest. Frame rates vary from 166 fps to 5 000 fps (ROI) for each camera in parallel.
A sequence of user-defined projection patterns is uploaded into the DLS Module memory (RAM) and the data can be used for a single projection or for a projection loop. The illuminated object is recorded by the sensors and the images are buffered in the on-board RAM that holds up to 1 592 pictures (10 bit, 1 920 x 1 200 pixels), ready for download to the PC for further processing. All data flow operations are executed by one FPGA device enabling the outstanding real-time precision.
Streaming data to and from the on‑board RAM is realised by the USB 3.0 SuperSpeed transfer implemented on the DLS Module system. The upload is further improved by lossless compression during the loading process and pixel binning is available as an option for the image download.
System Control of DLS Modules
An easy‑to‑integrate application programming interface (API) supports rapid system development. The DLS API functions are designed to build an application with a minimum of programming effort providing maximum control capabilities at the same time. The user can define any type of pattern sequence that may differ in bit depth, number of pictures, and frame rate. The DLS API is implemented as a dynamic-link library (DLL), it is portable and can be used in various programming environments.
Extended Software Option
An additional software package zSnapper® SDK (zSn.dll) is available as an optional extension for DLS Modules enabling high-speed and high‑precision 3D coordinate acquisition. This powerful 3D measurement software has been developed for the ViALUX 3D scanners and is now released on module level. It delivers (x, y, z) coordinates directly and automatically for use in 3D machine vision.
