A control method of a fastening tool for fastening a component part includes photographing a fastening portion of the component part through a camera portion mounted on the fastening tool. The control method includes pre-processing that rotates an input image, which has been photographed by the camera portion, to match with representative model image. The control method includes estimating the fastening portion through an inference process through a convolutional neural network (CNN) algorithm-based image classification work on a video input image of a same fastening portion finished with the pre-processing work. The control method also includes setting a torque value that is matched with a recognized fastening portion when a probability value of the fastening portion in the inference process exceeds a predetermined reference ratio.

Fastening tool system and control method thereof

A fastening tool system for fastening a component part by using a supplied power includes: a camera portion mounted on a fastening tool to photograph a fastening portion of the component part; an image input portion for inputting an image photographed from the camera portion when a distance with the fastening portion measured through a distance measurement sensor is within a predetermined distance; a communication portion for transmitting data by wireless communication; and a fastening portion determining portion that recognizes the fastening portion through machine learning algorithm-based image classification work for an input image of the camera portion and sets a torque value matched with the recognized fastening portion.

A wheel alignment measuring device using a body center line of a vehicle includes: front laser sensors provided at both sides of a front of a workbench on which the vehicle is disposed to measure positions of side panels each provided at both sides of a front of the vehicle; rear laser sensors at both sides of a rear of the workbench to measure positions of the side panels each provided at both sides of a rear of the vehicle; and a measuring unit configured to connect a center point A of a connection line connecting two points of a front of the side panels measured by the front laser sensors and a center point B of a connection line connecting two points of a rear of the side panels measured by the rear laser sensors to obtain a body center line C of the vehicle.
