Abstract
A simulation system includes a camera attached to an articulated robot and a simulation device. The camera transmits an image of a landmark arranged at a base in a manufacturing line in a real world to the simulation device. The simulation device analyzes markers evenly arranged on the landmark, estimates distortion of the base based on a shape of each of the markers and arrangement intervals between the markers viewed from the camera, reproduces distortion of the base in the manufacturing line reproduced in a 3D space, corrects teaching data in a process for working by the articulated robot on a workpiece on the distorted base in the 3D space, and gives a result of correction of the teaching data to a control device.

A simulation system comprising:
- a camera attached to a robot;
- and
- a simulation device, wherein
- the camera transmits an image of a landmark arranged at a base in a manufacturing line in a real world to the simulation device, and
- the simulation device
- analyzes a plurality of markers evenly arranged on the landmark in the image,
- estimates distortion of the base based on a shape of each of the plurality of markers and arrangement intervals between the plurality of markers viewed from the camera,
- reproduces based on a result of estimation, distortion of the base in the manufacturing line reproduced in a three-dimensional (3D) space,
- corrects in the 3D space, teaching data in a process for working by an articulated robot on a workpiece on the distorted base, and
- gives as feedback, a result of correction of the teaching data to a control device for the articulated robot.
A simulation method comprising:
- shooting an image of a landmark arranged at a base in a manufacturing line in a real world with a camera attached to an articulated robot;
- transmitting the image to a simulation device;
- analyzing a plurality of markers evenly arranged on the landmark in the image;
- estimating distortion of the base based on a shape of each of the plurality of markers and arrangement intervals between the plurality of markers viewed from the camera;
- reproducing based on a result of estimation, distortion of the base in the manufacturing line reproduced in a 3D space;
- correcting in the 3D space, teaching data in a process for working by the articulated robot on a workpiece on the distorted base;
- and
- giving as feedback, a result of correction of the teaching data to a control device for the articulated robot.
