Embodiment Construction

[0022] figure 1 It is a schematic hardware configuration diagram showing a main part of the inspection device 1 according to one embodiment of the present invention. The inspection device 1 is, for example, a device that performs an appearance inspection of a processed workpiece. The inspection device 1 includes a CPU 11 , a ROM 12 , a RAM 13 , a nonvolatile memory 14 , an interface 18 , an interface 19 , a bus 10 , an input / output device 60 , and an imaging device 70 .

[0023] The CPU 11 is a processor that controls the inspection device 1 as a whole. The CPU 11 reads the system program stored in the ROM 12 via the bus 10, and controls the entire inspection apparatus 1 in accordance with the system program.

[0024] The ROM 12 stores in advance system programs for executing various controls of the machine and the like.

[0025] The RAM 13 temporarily stores calculation data, input and output data, and the like.

[0026] The nonvolatile memory 14 is backed up by, for exam...

Abstract

It is possible to provide an inspection apparatus having a function of automatically checking a validity of an appearance inspection result without manual operation. An inspection apparatus for performing an appearance inspection using a plurality of images obtained by imaging an inspection target includes a determination unit that estimates an inspection result on each of the plurality of imagesbased on a predetermined relationship model between the image and the inspection result and calculates a comprehensive inspection result based on reliability of each of the inspection results on the plurality of images.

Description

technical field [0001] The present invention relates to an inspection device, and more particularly, to an inspection device having a function of confirming the validity of an automatic visual inspection result independent of manual labor. Background technique [0002] In the visual inspection process of inspection objects (workpieces after processing, etc.), inspections have been performed by human eyes. In recent years, inspections in which an image of an inspection object is captured by a camera and the image is processed to perform inspection have been widely performed. [0003] Recently, machine learning such as deep learning is used for appearance inspection. By using machine learning, it is possible to accurately perform inspections, such as the judgment of damage and dents, where human beings cannot precisely define the judgment criteria with numerical values. [0004] Japanese Patent Application Laid-Open No. 2011-007553 describes changing optical conditions for e...
