Contactless scanning device for constructing synthesis image of apple in e.g. industrial field, has camera including sensor placed in optical axle, where distance between sensor and mirror is less than distance between pattern and mirror

摘要

The device has a projector (8) including a light source (10) e.g. filament type white light source, and a test pattern (12) defining an undeformed speckle effect comprising multitude of predetermined color and/or light intensities, where the pattern is in the form of a translucent/transparent plate. A camera (9) has a photosensitive sensor (17) i.e. charge coupled device type sensor, placed in a main optical axle (13) of the projector, where a distance between the sensor and a semi-reflecting mirror (18) is less than a distance between the pattern and the mirror.
