| Abstract: | Commonly grasp verification approach involves using the opening width of the robot's gripper. However, methods based on the opening width of the gripper may not apply to slender objects. In this study, we propose a grasp verification method using background subtraction. Our proposed method uses depth information to mask the background, isolating only the images of the gripper and the grasped object. Subsequently, a difference image is created by comparing the current image with the pre-grasp state, and the grasp state is detected based on the magnitude of the observed changes. The method minimizes environmental influences by masking the background, enabling highly accurate grasp verification even for complex objects. Through experiments, we validate the effectiveness of the proposed method. |
