Technology selection guide
Choose the image information the application needs—not the most complex camera available. This guide compares planar 2D imaging with depth and spatial 3D vision for UK manufacturing projects.
Direct answer
2D vision analyses a flat image for contrast, shape, colour, code and planar position. 3D vision also measures depth, height or spatial pose. A 2D system can be the better choice when products stay on one plane; 3D is considered when height, tilt, overlap or a full spatial pose affects the robot action.
2D vision can inspect features, read codes, locate objects on a conveyor and calculate planar robot coordinates. It is often easier to light, calibrate, process and maintain where product height is controlled.
3D methods measure surface height or spatial position. They can support random bin picking, dimensional profiles, depalletising and tasks where the robot must approach a tilted or stacked object.
Decision to action
Each stage is designed against representative products, real timing and the required physical outcome.
Define exactly what must be detected or located.
List the height, pose, surface and presentation range.
Prove the simplest suitable imaging method.
Validate calibration, timing and physical response.
Application opportunities
Final suitability follows from the product, presentation, rate, environment and acceptance criteria.
Questions manufacturers ask
Use these answers to frame the first application review and the evidence needed next.
Not automatically. Accuracy depends on the camera method, optics, calibration, field of view, surface and working distance. The application determines which measurement is meaningful.
Yes when the required target information is planar or when the missing coordinates are otherwise constrained. A six-axis robot does not automatically require a 3D camera.
Yes. A 3D sensor might locate a part while a 2D camera verifies identity or surface detail. The extra complexity should be justified by a clear production requirement.
3D is usually considered because parts vary in height, tilt and overlap. The exact sensor and grasp strategy still need trials with representative parts and bins.
