Image acquisition
Select the camera, lens, field of view, resolution, trigger and enclosure around the feature that must be seen. Camera specification follows the inspection or guidance requirement—not megapixels alone.
Direct answer
A fixed camera often suits a stable repeated scene and can capture independently of robot movement. An eye-in-hand camera can reach several viewpoints or inspect a larger work area. Cycle time, lighting, calibration, cable routing and maintenance determine the better arrangement.
Field of view, working distance, feature size and depth of field determine the useful image scale. We calculate the required pixel resolution and select optics around the smallest meaningful feature.
2D vision is often the most direct route when the relevant feature lies in a controlled plane. 3D can add value when height, pose, overlap or variable presentation is central to the task.
System sequence
Every stage is tested against the product, timing, interfaces and agreed response.
Define the smallest feature and acceptable variation.
Set field of view, distance, angle and depth range.
Control motion blur, focus, exposure and triggering.
Relate image coordinates to the robot or line.
Typical applications
Final suitability and performance are confirmed only after review of the complete production application.
Application questions
These answers provide a starting point. Product trials and line data determine the project specification.
No. Many conveyor and planar applications are solved more simply with calibrated 2D vision. 3D is considered where depth, random pose, overlap or height variation makes it useful.
Yes. Eye-in-hand vision can inspect from several viewpoints or refine a final approach. Cable routing, robot motion, calibration and cycle-time impact must be engineered.
Resolution is derived from the field of view and the smallest feature or positional change that must be detected, with an appropriate engineering margin.
