    Abstract: Provided are a method and a device that can efficiently generate a training dataset. Object information is associated with a visual marker, a training dataset generation jig that is configured from a base part and a marker is used, said base part being provided with an area that serves as a guide for positioning a target object and said marker being fixed on the base part, the target object is positioned using the area as a guide and in this condition an image group of the entire object including the marker is acquired, the object information that was associated with the visual marker is acquired from the acquired image group, a reconfigured image group is generated from this image group by performing a concealment process on a region corresponding to the visual marker or the training dataset generation jig, a bounding box is set in the reconfigured image group on the basis of the acquired object information, information relating to the bounding box, the object information, and estimated target object position information and posture information are associated with a captured image, and a training dataset for performing object recognition and position/posture estimation for the target object is generated.

    Abstract: To provide a method whereby viscoelasticity of an object can be measured nondestructively and in non-contact fashion in a short time. By this method, elastic waves and light are radiated to an object and the viscoelasticity of an object is measured nondestructively and in non-contact fashion using a shadow change based on a change in the direction of a line normal to the surface of the object. Specifically, the present invention has an elastic wave transmission step for pressurizing or exciting the object by elastic waves and causing a minute displacement of the object surface shape, a photoirradiation step for radiating light to the minutely displaced object surface, an image acquisition step for acquiring a shadow change based on a change in the direction of a line normal to the object surface, and a viscoelasticity estimation step for processing an image of the acquired shadow change and calculating a viscoelasticity.
