Abstract: Provided is a highly reliable X-ray inspection device having two line sensors, in which accurate inspection results can be obtained even when there is displacement of the mounting position of the line sensors. The X-ray inspection device is provided with a conveyor unit for conveying an article, an X-ray emitter, a first line sensor, a second line sensor, a detection unit, and a corrected-image generation unit. The X-ray emitter emits X-rays to the article conveyed by the conveyor unit. The first line sensor detects, in a low energy band, X-rays that have passed through the article. The second line sensor detects, in a high energy band, X-rays that have passed through the article. The detection unit detects positional displacement of the second line sensor with respect to the first line sensor in horizontal direction and vertical direction.

Abstract: [Problem] To enable overlapping products to be distinguished.[Solution] A method of generating training data 40 is a method of generating training data 40 used to generate a computing unit X for a product identification apparatus 10 that computes, from a group image in which there are one or more types of products G, the quantities of each of the products G included in the group image. The training data 40 includes plural learning group images 41 and labels 42 assigned to each of the plural learning group images 41. The method of generating the training data 40 includes a first step of acquiring individual images 43a1 to 43a6, 43b1 to 43b6, 43c1 to 43c6 in each of which there is one product G of one type and a second step of generating the plural learning group images 41 including one or more of the products G by randomly arranging the individual images. The plural learning group images 41 generated in the second step include learning group images 41 in which the individual images at least partially overlap each other.
