1. An image analysis apparatus for analyzing a camera image, which analyzes a fisheye lens camera image, the image analysis apparatus comprising:
a memory; and
a processor, wherein the processor, when executing program instructions stored in the memory, is configured to perform:
a pre-processing operation of segmenting an input image into segmented images with a preset size field of view so that some regions of the displayed image overlap in the segmented images, performing dewarping on each of the segmented images, then combining the segmented images on which the dewarping is performed using a preset combination method, and to generate an analysis image;
an image analysis operation of receiving the analysis image and detecting an object; and
a post-processing operation of removing a result recognized as a duplicate from a detection result of the object of the image analysis operation,
wherein the analysis image is generated by concatenating the segmented images on a predetermined grid,
wherein the segmented images are images of different areas of a fisheye lens camera image, and
wherein the post-processing operation includes determining a duplicate object on the basis of coordinates of a region of the object in the fisheye lens camera image converted from coordinates of the segmented image of a bounding box and removing the result recognized as the duplicate from the detection result of the object.
