Technical and Delivery Questions
Is 3D vision always more suitable than 2D vision?
No. 2D is often sufficient for appearance, print and planar features. 3D becomes relevant when height, depth, volume or spatial pose is part of the requirement.
What determines 3D measurement accuracy?
Sensor capability, field of view, optics, calibration, surface material, vibration, installation stability, algorithm settings and the reference method all contribute.
Can the output connect to a robot?
Yes, when the coordinate chain and interface are defined. Outputs may include target position, pose, grasp candidates or obstacle geometry through an agreed API or robot interface.
