MOTION CONTROL: Cognex Corp. 3D-LocateTM is a library of 3-D vision software tools that expands application possibilities in vision-guided robotics, assembly, and inspection.
Cognex 3D-Locate delivers accurate, real-time, three-dimensional position information that enables automation equipment to work with a wider variety of parts, including items that are stacked or tilted. Using 3D-Locate can improve vision performance for challenging applications such as logistics, robot-guided de-palletizing and precision assembly, and it can eliminate the need for expensive mechanical fixtures or measurement devices. Cognex 3D-Locate can also be used in combination with Cognex code reading, gauging, and inspection tools.
Cognex 3D-Locate uses multiple sets of two-dimensional features found by Cognex’s patented geometric pattern matching tool, PatMax®, to determine an object’s precise three-dimensional orientation. PatMax tolerates non-uniform lighting and remains reliable even when patterns are partly covered, ensuring accurate part location even in the most challenging settings and conditions. Cognex 3D-Locate can also use input from other Cognex location tools such as SearchMaxTM and PatFlex® to help determine part orientation.
Application performance is enhanced by high-precision Cognex calibration tools that adjust for optical distortion and camera position, and synchronize cameras with moving elements like robot grippers - key to the success of any 3-D application. PC-based 3D-Locate can handle high throughput applications, and users have the option to choose from a wide range of industrial cameras.
3D-Locate can be used in: single camera applications that need more information than a 2-D approach can offer; robot-mounted single or stereo camera guidance systems; work cells with multiple fixed-mount cameras, to eliminate mechanical fixtures; and dimensioning, sorting and picking applications on conveyor lines
3D-Locate is available as part of the Cognex CVL software library.
