CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of priority to Korean Patent Application No. 10-2019-0096900, filed on Aug. 8, 2019, the entire contents of which are incorporated herein by reference.

FIELD

The present disclosure relates to a device and a method for recognizing a motion in a vehicle.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

A device control technology using motion recognition has recently been introduced into a vehicle. Some vehicle manufacturers have even made mass production of a vehicle equipped with the motion recognition technology using a camera. Users may use the motion recognition technology to more conveniently control various devices in the vehicle.

However, a recognition rate of the motion recognition technology is still low, and misrecognition occurs when motions generated from a plurality of users in the vehicle are recognized.

SUMMARY

The present disclosure has been made to address the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.

An aspect of the present disclosure provides a device and a method for recognizing a motion in a vehicle that may recognize motions generated from a plurality of users in the vehicle.

Another aspect of the present disclosure provides a device and a method for recognizing a motion in a vehicle that may improve a recognition rate of a motion generated from a user in the vehicle.

Technical problems to be addressed by the present inventive concept are not limited to the aforementioned problems, and any other technical problems not mentioned herein will be clearly understood from the following description by those skilled in the art to which the present disclosure pertains.

In one aspect of the present disclosure, a device for recognizing a motion in a vehicle is provided. One form of a device includes a camera configured to acquire a user image, and a controller that is configured to divide the user image into a first region, a second region, and a third region in which the first region and the second region overlap each other, and to recognize a motion of a user occurring in at least one of the first region, the second region, or the third region.

In some implementations, the first region may include a first main region and a first sub region, and the second region includes a second main region and a second sub region.

In some implementations, the controller may assign a higher priority to a motion of the user recognized in the first main region than a motion of the user recognized in the first sub region, and assign a higher priority to a motion of the user recognized in the second main region than a motion of the user recognized in the second sub region.

In some implementations, the controller may generate a control command corresponding to the recognized motion of the user based on the priority.

In some implementations, the controller may generate a corresponding control command when the motion of the user occurring in the first region is recognized as a motion associated with control of driving of the vehicle, and not generate the control command when the motion of the user occurring in the second region is recognized as the motion associated with the control of the driving of the vehicle.

In some implementations, the controller may generate a corresponding control command when the motion of the user occurring in the second region is recognized as a motion associated with control of an infotainment system while the vehicle is traveling, and not generate the control command when the motion of the user occurring in the first region is recognized as the motion associated with the control of the infotainment system.

In some implementations, the controller may determine the motion of the user as a motion of a user in the first region or the second region when the motion of the user occurring in the third region is recognized, not generate a control command when the motion of the user is recognized as a motion associated with control of an infotainment system of the user in the first region, and generate the control command when the motion of the user is recognized as a motion associated with control of a navigation of the user in the second region.

In some implementations, the controller may determine priorities of the motion of the user recognized in the first region and the motion of the user recognized in the second region based on a traveling environment of the vehicle.

In some implementations, the controller may recognize at least one of a first motion of the user occurring in the first region, a second motion of the user occurring in the second region, or a third motion of the user occurring in the third region, and generate a corresponding control command when at least two of the first motion, the second motion, or the third motion correspond to a preset motion combination.

In some implementations, the controller may set a size or width of the first region, the second region, or the third region based on a frequency or pattern of the motion of the user occurring in at least one of the first region, the second region, or the third region.

In some implementations, the user may include a first user in a driver's seat and a second user in a passenger seat, wherein the first region may be defined as a region including the driver's seat, and wherein the second region may be defined as a region including the passenger seat.

In some implementations, the controller may recognize the motion of the user occurring in the third region as the motion of the user occurring in the first region or the second region based on a direction of entry of the motion of the user into the third region or a pre-stored user image.

In some implementations, the camera may include a first camera for capturing a user image of the first user, and a second camera for capturing a user image of the second user.

In some implementations, the controller may recognize the motion of the user occurring in at least one of the first region, the second region, or the third region based on priorities preset to the first region and the second region.

In another aspect of the present disclosure, a method for recognizing a motion in a vehicle is disclosed. In one form, a method includes acquiring, with a camera, a user image; dividing, with a controller, the user image into a first region, a second region, and a third region in which the first region and the second region overlap each other; and recognizing, with the controller, a motion of a user occurring in at least one of the first region, the second region, or the third region.

In some implementations, the first region may include a first main region and a first sub region and the second region may include a second main region and a second sub region.

In some implementations, the recognizing of the motion of the user occurring in at least one of the first region, the second region, or the third region may include assigning a higher priority to a motion of the user recognized in the first main region than a motion of the user recognized in the first sub region, and assigning a higher priority to a motion of the user recognized in the second main region than a motion of the user recognized in the second sub region.

In some implementations, recognizing of the motion of the user occurring in at least one of the first region, the second region, or the third region may include generating a corresponding control command when the motion of the user occurring in the first region is recognized as a motion associated with control of driving of the vehicle, and not generating the control command when the motion of the user occurring in the second region is recognized as the motion associated with the control of the driving of the vehicle.

In some implementations, recognizing the motion of the user occurring in at least one of the first region, the second region, or the third region may include generating a corresponding control command when the motion of the user occurring in the second region is recognized as a motion associated with control of an infotainment system while the vehicle is traveling, and not generating the control command when the motion of the user occurring in the first region is recognized as the motion associated with the control of the infotainment system.

In some implementations, recognizing the motion of the user occurring in at least one of the first region, the second region, or the third region may include recognizing the motion of the user occurring in at least one of the first region, the second region, or the third region based on priorities preset to the first region and the second region.

Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
