Montreal, Quebec – High-Tech Digital Inc., a Matrox Imaging distributor, will be at MD&M West from February 5-7, 2019, demonstrating guided welding of metal mesh used for blood vessel stents.
From booth #780, High-Tech Digital will showcase Matrox Image Library (MIL) software and a Matrox Rapixo CXP frame grabber powering a CoaXPress (CXP) camera to perform high-resolution image capture at high speeds. The demonstration centers on the use of machine vision as an ideal solution for high-precision laser guidance for metal mesh welding.
Optimized stent mesh welding with MIL software tools, CXP frame grabber & camera
High-Tech Digital’s demonstration highlights typical challenges in this type of process; for example, because of the highly reflective nature of the metal, reflective “hot spots” caused by illumination can create erroneous positioning and thus impact production. MIL tools are ideally suited to alleviate these issues. The Color Projection tool converts the color image of the metal mesh to monochrome, to combat the illumination issues that cause such “hot spots”. Pattern recognition was used to precisely locate the welding points for laser position feedback – specifically Geometric Model Finder (GMF) – identifying the position and orientation of the mesh peaks.
This demo also includes a Matrox Rapixo CXP frame grabber paired with a CXP camera, namely, CP70-16-M/C-148 from Optronis, that can acquire 16MP images at 300fps. The Matrox Rapixo CXP’s four channels acquires those images at a rate of 50Gbps, ensuring the high-resolution, high-speed image capture integral for the system’s performance.
Product overviews
MIL is a comprehensive collection of software tools for developing machine vision, image analysis, and medical imaging applications. It features tools for every step in the process, from application feasibility to prototyping, through to development and ultimately deployment. Carefully optimized for speed, these tools help address the severe time constraints encountered in many applications. Interactive coding and programming functions facilitate image capture, processing, analysis, annotation, display, and archiving tasks.
Matrox Rapixo CXP is a new generation of frame grabbers, supporting version 2.0 of the CoaXPress (CXP) digital interface standard for machine vision applications. With support for data rates of up to 12.5Gbps (CXP-12), the Matrox Rapixo CXP also includes four connections for interfacing to independent cameras as well as for handling higher data rates through connection aggregation. Power-over-CoaXPress (PoCXP) support on each connection simplifies system configurations.
