Laundry treating apparatus having camera, and control method thereof
The present application relates to a laundry treating apparatus. More specifically, the present application relates to a laundry treating apparatus having a camera and a control method thereof. One embodiment of the present application provides a method including: causing a drum to move laundry inside the drum; generating time-series images of movement of the laundry by capturing an inside of the drum while the laundry moves over time; determining a movement state of the laundry based on the generated time-series images while the drum rotates at a revolutions per minute (RPM); controlling the RPM of the drum based on the movement state of the laundry to increase a laundry spread value; and after the laundry spread value has increased, increasing the RPM of the drum to perform a spinning process.
1. A method comprising:
causing a drum to move laundry inside the drum;
generating time-series images of movement of the laundry by capturing images of an inside of the drum while the laundry moves over time;
determining a movement state of the laundry based on the generated time-series images while the drum rotates at a defined revolutions per minute (RPM);
analyzing the generated time-series images to determine a current laundry spread value related to the movement state of the laundry;
determining, based on the time-series images, laundry spread value evaluation information related to the movement state of the laundry, wherein one of the laundry spread value evaluation information includes the current laundry spread value;
displaying the laundry spread value evaluation information on a display to a user;
controlling the RPM of the drum based on the movement state of the laundry to achieve a first laundry spread value from among a plurality of values; and
after the first laundry spread value is achieved, increasing the RPM of the drum to perform a spinning process,
wherein displaying the laundry spread value to the user comprises:
generating an augmented reality image corresponding to each of the laundry spread value evaluation information; and
displaying, on the display, the augmented reality image of each of the laundry spread value evaluation information to permit the user to determine a laundry spread state in the drum.
2. The method of claim 1 , further comprising displaying the time-series images on the display.
3. The method of claim 2 , wherein the time-series images are generated by capturing images of the inside of the drum at a first time interval and extracting discontinuous time-series images having a second time interval from the time-series images, wherein the second time interval is larger than the first time interval.
4. The method of claim 1 , further comprising transmitting the time-series images to an external terminal through a communication module.
5. The method of claim 1 , further comprising:
displaying, on the display, the time-series images and each of the augmented reality images superimposed on the displayed time-series images.
6. The method of claim 5 , further comprising:
displaying, on the display, an animation corresponding to each of the laundry spread value evaluation information to illustrate the laundry spread state in the drum.
7. The method of claim 1 , further comprising obtaining, via a user interface, RPM information of the drum for feedback-control from the user.
8. The method of claim 7 , wherein the laundry spread value is increased based on analyzing the RPM information of the drum.
9. The method of claim 8 , further comprising re-extracting laundry spread value evaluation information after the feedback-control, and providing the re-extracted information to the user.
