Information estimation method and device, model retrieval method and device and model alignment method and device

The invention provides an information estimation method. The method comprises the steps of obtaining a first image; and performing attitude and/or key point estimation on the object in the first imageby using a neural network. The invention furthermore provides a model retrieval method, which comprises the steps of obtaining an image, and carrying out model retrieval according to the image to obtain a target model matched with an object in the image. The invention further provides a model alignment method, which comprises the steps of obtaining a first image; and combining the object in the first image with a target model. 本公开提供一种信息估计方法，包括获取第一图像；以及利用神经网络对所述第一图像中的对象进行姿态和/或关键点估计。本公开还提供一种模型检索方法，包括获取图像，以及根据所述图像进行模型检索，获得与所述图像中的对象匹配的目标模型。本公开还提供一种模型对准方法，包括获取第一图像；以及将所述第一图像中的对象与目标模型。
