Abstract
An image matching method and apparatus are disclosed. The method according to the present embodiment comprises: a step of acquiring source image; a step of acquiring a transformation image, by converting the display mode of the source images into a top view and adjusting the brightness thereof through auto exposure (AE); a step of acquiring image information; and a step of generating a target image comprising a first area and a second area in an overlap area in which pixels of a corrected transformation image are disposed on the basis of the image information, wherein the correction comprises gradation correction of the pixels of an image disposed in the first area and pixels of an image in the second area.

A method of processing an image, for generating one matching image from first and second images acquired by a plurality of cameras of a vehicle, wherein the matching image includes:
- a first region with the first image disposed thereon;
- a second region with the second image disposed thereon;
- and
- a boundary formed by the first region and the second region,
- wherein the first region includes a third region to a preset position from the boundary, and
- wherein brightness of the third region is increased or reduced based on brightness of the first region and brightness of the second region.
An image matching method for a vehicle, the method comprising:
- extracting a plurality of pieces of image information including first image information and second image information using a plurality of cameras installed in the vehicle;
- and
- correcting and matching the plurality of pieces of image information to output a target image,
- wherein the target image includes a first region with an image formed using the first image information disposed thereon, and a second region with an image formed using the second image information disposed thereon and including a boundary formed to contact the first region, and
- wherein the first region includes a region with brightness that is increased or reduced away from the boundary.
An image matching apparatus comprising:
- a setting unit configured to set an overlapping region and a non-overlapping region in two different images;
- an extraction unit configured to extract image information of the overlapping region in each of the two images;
- a determination unit configured to determine a correction reference value based on the extracted image information;
- a correction unit configured to apply gradation according to the correction reference value to correct brightness of the overlapping region;
- and
- a matching unit configured to match the two images based on the corrected overlapping region.
