阅读说明：本技术 图像生成装置、图像生成方法、程序以及记录介质 (Image generation device, image generation method, program, and recording medium ) 是由 陈斌 沈思杰 于 2019-11-12 设计创作，主要内容包括：提供一种图像生成装置,其能够用计算处理能力不太高的装置轻松地生成合成图像等,并能够抑制合成图像所表现的被摄体的再现性的降低。该图像生成装置基于由飞行体拍摄到的多个拍摄图像来生成合成图像,包括进行与合成图像的生成相关的处理的处理部。处理部获取由飞行体具备的拍摄装置拍摄到的多个拍摄图像,基于多个拍摄图像,生成三维模型,获取拍摄多个拍摄图像时的拍摄装置的各个姿势,基于拍摄装置的各个姿势和三维模型,计算拍摄多个拍摄图像时的拍摄装置的各个位置与三维模型之间的距离,并根据拍摄装置的各个位置与三维模型之间的距离,调整多个拍摄图像的尺寸,对尺寸调整后的多个拍摄图像进行合成而生成合成图像。(Provided is an image generation device capable of easily generating a composite image or the like by a device having a low computational processing capability and suppressing a reduction in reproducibility of an object represented by the composite image. The image generation device generates a composite image based on a plurality of captured images captured by a flying object, and includes a processing unit that performs processing related to generation of the composite image. The processing unit acquires a plurality of captured images captured by an imaging device provided in the flying object, generates a three-dimensional model based on the plurality of captured images, acquires the respective postures of the imaging device when the plurality of captured images are captured, calculates the distances between the respective positions of the imaging device and the three-dimensional model when the plurality of captured images are captured based on the respective postures of the imaging device and the three-dimensional model, adjusts the sizes of the plurality of captured images based on the distances between the respective positions of the imaging device and the three-dimensional model, and generates a composite image by combining the plurality of captured images after the size adjustment.)
