Measuring, Gauging, and Verifying Tolerances
Manufacturing requirements for measurement range from presence verification to checking high-precision dimensional accuracy and geometrical tolerances. Attention to the inspection environment and image quality is as important as the vision algorithms themselves. DALSA sub-pixel measurement tools, combined with the right optics and stable lighting, provide the precision and repeatability to ensure manufacturing accuracy.
Measurement Applications
Teledyne DALSA Machine Vision Capabilities and Tools
• High speed, low light, high resolution image capture
• position (search) tools to accurately landmark measurements on moving parts
• Calibration tools to remove camera misrepresentation and translate sub-pixel measurements locally or globally into real world units
• Preprocessing tools to manipulate or improve the camera image to highlight features to measure
• Edge finding tools to accurately find edge transition on parts for gauging
• Shape finding tools to locate distinct shapes like corners on parts
• Geometric fitting tools to fit lines, angles, arcs, and circles to edge points
• Math tools to create custom measurements that span multiple cameras
• Laser tools for measuring height on parts determined by angle of projected laser lines
• Bead tool to measure thickness and uniformity of adhesive beads or similar applications
• Color tools for verifying the amount and location of colored elements.
