TRAINING DEVICE, TRAINING METHOD, STORAGE MEDIUM, AND OBJECT DETECTION DEVICE

A training device includes a storage device that has stored a program, and a hardware processor, in which the hardware processor executes the program stored in the storage device, thereby acquiring a captured image of a road, adding a computer graphic image of an object present on a road to an actually captured image based on the captured image, and training parameters of a model to output a type of the object when an image is input using a type of the added computer graphic image as teacher data.
