Image processing device, image processing method, and non-transitory storage medium
The present invention provides an image processing apparatus ( 10 ) including a detection unit ( 12 ) that detects a plurality of predetermined points of a body of each of a plurality of persons from an image in an image circle of a fisheye image, a gravity direction determination unit ( 13 ) that determines a gravity direction in a position of each of the plurality of persons from the plurality of predetermined points, a reference point decision unit ( 14 ) that decides a reference point, based on the gravity direction in the position of each of the plurality of persons, a complementary circular image generation unit ( 16 ) that generates a complementary circular image that is a circular image acquired by adding a complementary image to the image in the image circle of the fisheye image, and that has, as a center, the reference point different from a center of the image in the image circle, and an expansion unit ( 17 ) that panoramically expands the complementary circular image, based on the reference point, and generates a panoramic image.
1 . An image processing apparatus comprising;
at least one memory storing instructions and
at least one processor configured to execute the instructions to:
receive a fisheye image;
determine a reference point regarding the fisheye image based on information related to a person shown in the fisheye image; and
generate a panoramic image based on the reference point regarding the fisheye image.
2 . The image processing apparatus according to claim 1 , wherein the information related to a person shown in the fisheye image includes a gravity direction in a position of the person.
3 . The image processing apparatus according to claim 1 , wherein the at least one processor further configured to execute the instructions to generate a complementary circular image,0 wherein the instruction to generate the panoramic image uses the complementary circular image for generating the panoramic image.
4 . The image processing apparatus according to claim 3 , wherein the complementary circular image is used in a case where the reference point dose not coincide with a center of an image regarding the fisheye image.
5 . An image processing method executed by a computer, the method comprising;
receiving a fisheye image;
determining a reference point regarding the fisheye image based on information related to a person shown in the fisheye image; and
generating a panoramic image based on the reference point regarding the fisheye image.
6 . The image processing method according to claim 5 , wherein the information related to a person shown in the fisheye image includes a gravity direction in a position of the person.
7 . The image processing method according to claim 5 , wherein the computer generates a complementary circular image, wherein the computer uses the complementary circular image for generating the panoramic image.
8 . The image processing method according to claim 7 , wherein the complementary circular image is used in a case where the reference point dose not coincide with a center of an image regarding the fisheye image.
