Multicamera Fusion-Based Leather Defects Marking System

الملخص EN

Real-time acquisition of ultra-high wide view video images is essential in leather defects marking systems because this enables either the leather manufacturing process or an inspector to identify leather defects.

The major challenge in this work is blending and stitching the multiple camera views to form a single fusion image map.

In the fusion video image, the viewer is quite sensitive to incorrect stitching and blending when the marking pen is passing through the border between views.

Hence, a set of geometric and photometric corrections have to be applied to each camera view in addition to careful blending of the image borders.

In this paper, we present a real-time image capturing system that uses four cameras at 30 fps and stitches their views together to create a panoramic video with a resolution of 1280×960 px.

The real-time fusion video image can be observed on a large screen next to the leather defects marking system and no manual alignment is necessary, resulting in savings in both labor and time.
