IPC: G01N21/88
Filed: 1988-12-28
Abstract: PURPOSE:To decrease the amount of data and to make it possible to perform checking at a high speed by dividing the inner surface of a container having a seamed part into a plurality of fields of view in the specified direction, picking up the image, taking out the specified data for every scanning line of the binary coded image, and compressing the image data. CONSTITUTION:The inner surface of a container 1 such as paper cup having a seamed part 2 is divided into a plurality of fields of view within specified angle ranges in the specified direction so that the seamed part is not in parallel or close to parallel with the scanning direction. The image of the container is picked up with a two-dimensional image sensing device 6 such as a TV camera. The obtained image signal is made to be an at least binary coded signal. The initial rise-up and the final fall of the image, their positions and the length of the line are taken out for every scanning line of the binary coded image. The image data are compressed. The data are stored in addresses corresponding to the coordinates of the scanning line in the vertical direction in a specified memory. Finally, the seamed part and a contaminated part are separated, and pass or fail is judged. Thus the amount of data is decreased, and a high speed is obtained.
