Title: OBJECT MULTI-PERSPECTIVE INSPECTION APPARATUS AND METHOD THEREFOR
Abstract:
It is therefore an objective to provide an object multi-perspective inspection apparatus (1) and a method therefor. The apparatus (1) includes an image capture device (10); an inspection site (11) and at least two reflection devices (12), being arranged for reflecting simultaneously to the image capture device (10) at least two different side views of the object located in the inspection site (11); wherein: the image capture device (10) has a field of view including the at least two different side views of the reflection. By introducing reflection devices (12) into the inspection apparatus (1) to enable the image capture device (10) to "see" the part from multiple views at once, multiple surfaces can be inspected at once, in one image frame, without having the need to reposition the reflection device (12), the camera (10) and/or the object for every single surface. There are more than one reflection devices (12) placed in the camera's field of view to assist the inspection process by exploiting otherwise hidden surfaces of any given solid object. The effort inspecting every single part from multiple sides is reduced. Therefore, the period of the inspection cycle time can be reduced and inspection on the level of multi-surfaces becomes possible increasing overall quality.
