Abstract
Provided are an image alignment apparatus and an image alignment method using the same. The image alignment apparatus includes a first conversion function estimation unit for estimating a first conversion function based on feature point information that is extracted from a first image, which is captured by using a first image sensor, and a second image, which is captured by using a second image; and a second conversion function estimation unit for estimating a second conversion function based on motion information that is extracted from the first image and the second image.
Claims19
An image alignment apparatus comprising a hardware processor to implement:
- a first conversion function estimation unit configured to estimate a first conversion function based on feature point information, the feature point information being extracted from a first image, which is captured by using a first image sensor, and a second image, which is captured by using a second image sensor that is different from the first image sensor;
- a second conversion function estimation unit configured to estimate a second conversion function based on a similarity between a first motion vector in the first image and a second motion vector in the second image;
- and
- an alignment unit configured to align the first image with the second image by using the first or second conversion function.
An image alignment method comprising:
- estimating a first conversion function based on feature point information, the feature point information being extracted from a first image, which is captured by using a first image sensor, and a second image, which is captured by using a second image sensor that is different from the first image sensor;
- estimating a second conversion function based on a similarity between a first motion vector in the first image and a second motion vector in the second image;
- and
- aligning the first image with the second image by using the first or second conversion function.
