Abstract: A recognition device includes a data extraction unit, a recognition unit, and a ratio estimation unit. The data extraction unit acquires related information related to a target in a recognition target image which is a post-image obtained through photographing before and after treatment on a container that stores the target, and extracts recognition target data which is a combination of the recognition target image and the related information The recognition unit accepts the recognition target data as an input to a model learned in advance and outputs a recognition result obtained by recognizing an area where at least the container, the target, and a portion other than the target are divided by an output of the model. The ratio estimation unit estimates a ratio of the target in the recognition target image based on the recognition result and an area ratio in a pre-stored pre-image obtained through the photographing before and after the treatment.
