Apparatus and operating method for displaying augmented reality object
A display apparatus and an operating method thereof obtain at least one first sensor data of a first point in time, receive a first image frame including a first augmented reality (AR) object corresponding to the first point in time, the first AR object generated by a first processor, based on the first sensor data, obtain second sensor data of a second point in time subsequent to the first point in time, correct the first AR object to a second AR object matched to the second point in time, based on the second sensor data, and display a second image frame including the second AR object.
1. A display apparatus, comprising:
a communication interface configured to receive a first image frame, including a first augmented reality (AR) object generated by a first processor at a first point in time, at a second point in time;
at least one sensor configured to obtain first sensor data of the first point in time and second sensor data of the second point in time subsequent to the first point in time;
a second processor configured to correct the first AR object to a second AR object matched to the second point in time, by controlling an operating frequency of the at least one sensor used to sense the first sensor data based on a result of comparing the first sensor data and the second sensor data; and
a display configured to display a second image frame including the second AR object,
wherein the second point in time and the first point in time have a difference greater than 16.6 ms, and wherein the second processor has a lower computation power than the first processor.
2. The display apparatus of claim 1 , wherein the second processor is configured to correct the first AR object to the second AR object by performing an operation for the image processing, based on a difference between the first sensor data and the second sensor data.
3. The display apparatus of claim 1 , wherein the second processor is configured to perform partially rendering the first AR object corresponding to a partial area in the first image frame; and
match the partially rendered first AR object to the second image frame corresponding to the second point in time.
4. A display apparatus, comprising:
a communication interface configured to receive a first image frame, including a first augmented reality (AR) object generated by a first processor at a first point in time, at a second point in time following the first point in time;
at least one sensor configured to obtain first sensor data of the first point in time and second sensor data of the second point in time subsequent to the first point in time;
a second processor configured to correct the first AR object to a second AR object matched to the second point in time, by controlling an operating frequency of the at least one sensor used to sense the first sensor data based on a result of comparing the first sensor data and the second sensor data; and
a display configured to display a second image frame including the second AR object,
wherein the second point in time and the first point in time have a difference greater than a predetermined reference time, and the second processor has a lower computation power than the first processor.
5. The display apparatus of claim 4 , wherein the predetermined reference time is 16.6 ms.
6. The display apparatus of claim 4 , wherein the second processor is configured to correct the first AR object to the second AR object by performing an operation for the image processing, based on a difference between the first sensor data and the second sensor data.
7. The display apparatus of claim 4 , wherein the second processor is configured to perform partially rendering the first AR object corresponding to a partial area in the first image frame; and
match the partially rendered first AR object to the second image frame corresponding to the second point in time.
