Abstract
Disclosed are an apparatus and method for adjusting a steering wheel, the apparatus including an image capturing unit configured to capture images of a current state of a steering wheel at multiple angles, an analysis unit configured to create leveling information on zero adjustment of the steering wheel by processing the image acquired by the image capturing unit, and a control unit configured to calculate an error from preset reference leveling information depending on the leveling information created by the analysis unit and performing the zero adjustment on the steering wheel by controlling a drive unit for operating the steering wheel depending on the calculated error.

An apparatus configured to adjust a steering wheel, the apparatus comprising:
- an image capturing module comprising a camera configured to capture images of a current state of a steering wheel at multiple angles;
- an analysis module configured to create leveling information on zero adjustment of the steering wheel by processing the image acquired by the image capturing module;
- and
- a control module configured to calculate an error from preset reference leveling information depending on the leveling information created by the analysis module and to perform the zero adjustment on the steering wheel by controlling a drive module configured to operate the steering wheel depending on the calculated error;
- wherein the analysis module further comprises a shape learning module configured to create reference leveling information by extracting a plurality of feature points related to a wheel shape from an image of a front side of the steering wheel;
- wherein the analysis module is configured to create the leveling information on the zero adjustment of the steering wheel by extracting the plurality of feature points related to the wheel shape from the image of the front side of the steering wheel acquired by the image capturing module;
- wherein the shape learning module is configured to create the preset reference leveling information by extracting the plurality of feature points from a reference image and measuring the angles between the plurality of feature points,
- wherein the analysis module is configured to create the leveling information by extracting the plurality of features from the image acquired by the image capturing module and measuring the angles between the plurality of feature points,
- wherein the control module is configured to calculate an error between an angle of the preset reference leveling information and an angle of the leveling information,
- wherein the analysis module is configured to measure a tilting angle of the steering wheel by processing an image of a lateral side of the current state of the steering wheel acquired by the image capturing module and create the leveling information on the zero adjustment of the steering wheel corresponding to the measured tilting angle, and
- wherein the control module is configured to control the drive module to set the tilting angle again, based on the error between the reference leveling information based on the neutral state and the leveling information, and
- wherein the shape learning module is configured to learn the wheel shape by performing rule-based learning or deep-learning-based learning on a database related to the image of the front side of the steering wheel.
