Image processing device, image processing method, and image processing program

An image processing method by an image processing device for stitching a plurality of pieces of image data obtained by capturing portions of an image capturing region with an overlap, the image processing method comprising:

• acquiring a plurality of pieces of frame data captured at the same time, from the plurality of pieces of image data;
• detecting a target object in an overlap region in which pieces of the frame data adjacent to each other overlap each other;
• setting, in the overlap region, a prohibited region through which a seam does not pass;
• and
• outputting connection frame data by connecting the plurality of pieces of frame data to each other in accordance with the seam,
• wherein setting the prohibited region comprises:
• (i) determining, in the overlap region, a first region that encompasses the detected target object, (ii) determining a second region which spans from a side of the first region to a side of the overlap region on an entrance direction side of the target object, and (iii) setting the prohibited region as including both of the first region and the second region.

A non-transitory computer readable storage medium having stored thereon an image processing program for causing one or more processors of an image processing device to perform an image processing method for stitching a plurality of pieces of image data obtained by capturing portions of an image capturing region with an overlap, the image processing method comprising:

• acquiring a plurality of pieces of frame data captured at the same time, from the plurality of pieces of image data;
• detecting a target object in an overlap region in which pieces of the frame data adjacent to each other overlap each other;
• setting, in the overlap region, a prohibited region through which a seam does not pass;
• and
• outputting connection frame data by connecting the plurality of pieces of frame data to each other in accordance with the seam,
• wherein setting the prohibited region comprises:
• (i) determining, in the overlap region, a first region that encompasses the detected target object, (ii) determining a second region which spans from a side of the first region to a side of the overlap region on an entrance direction side of the target object, and (iii) setting the prohibited region as including both of the first region and the second region.
