Cognex 3D vision software for robotics, assembly and inspection
Cognex Corporation's 3D-Locate is a library of 3D vision software tools, that expands application possibilities in vision-guided robotics, assembly, and inspection.
3D-Locate uses multiple sets of two-dimensional features found by Cognex's geometric pattern matching tool, PatMax, to determine an object's precise three-dimensional orientation, even when the object is stacked or tilted. It can eliminate the need for expensive mechanical fixtures or measurement devices.
PatMax tolerates non-uniform lighting and remains reliable even when patterns are partly covered, ensuring accurate part location, even in challenging settings and conditions. Cognex 3D-Locate can also use input from other Cognex location tools, such as SearchMax 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 3D 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 is particularly suited for:-
• Single camera applications, that need more information than a 2D approach can offer;
• Robot-mounted single or stereo camera guidance systems;
• Work cells with multiple fixed-mount cameras, to eliminate mechanical fixtures;
• Dimensioning, sorting and picking applications on conveyor lines.
The vision software can also be used in combination with Cognex code reading, gauging, and inspection tools.
