このような外観不良によって、網目状投影20(縦格子20aと横格子20b)が正常な形状と異なる形状を呈する。撮像手段がこの容器外観の網目状投影の画像20を取得する。
FIG. 1 shows an example of mesh projection. FIG. 1A shows a reticulated projection 20 of a container 14 having a normal appearance. The mesh projection 20 in this example is composed of a vertical grid 20a and a horizontal grid 20b.
FIG. 1 (b) shows a reticulated projection 20 of a container 14 having a poor appearance. The container 14 having a bad appearance has disadvantages such as a container bulge 22a, a container dent 22b, a flap peel 24a, and a fin twist 23b.
Due to such an appearance defect, the mesh projection 20 (vertical lattice 20a and horizontal lattice 20b) has a shape different from a normal shape. The imaging means obtains a mesh-like projection image 20 of the container appearance.

画像処理手段は、網目状画像20を入力し、この画像を濃淡画像を白黒2値にする「2値化」若しくは濃度変化から物体の境界を見出す「エッジ検出」を行って、網目形状データを得る。
この態様の良否判定は、正常な容器の網目形状データを、多数のデータから統計上に得、この正常容器の基準データと、被検査容器のデータとの対比で行う。
網目形状データを対比して容易に処理・判定することができる。
The image processing means inputs the mesh image 20 and performs “binarization” for converting the grayscale image into a black and white binary image or “edge detection” for finding the boundary of the object from the density change. obtain.
The quality determination of this aspect is performed by statistically obtaining the mesh shape data of a normal container from a large number of data and comparing the reference data of the normal container with the data of the container to be inspected.
It is possible to easily process and determine the mesh shape data in comparison.
