Live pig body size measuring method and device based on machine vision

The invention discloses a live pig body size measuring method and device based on machine vision. The live pig body size measuring method comprises the following steps: collecting identity information of a live pig; obtaining a target three-dimensional pig body image corresponding to the current position and image data of a live pig measuring station; inputting the target three-dimensional pig body image and the image data of the live pig measurement station into a pre-trained body size measurement model, performing prediction operation on the target three-dimensional pig body image and the image data through the body size measurement model, and outputting pig body size parameters; and generating body size measurement data of the live pig according to the body size parameter of the pig and the identity information of the live pig. The accuracy of measuring the body size of the live pig can be improved. 本申请公开了一种基于机器视觉的生猪体尺测定方法及装置。该生猪体尺测定方法包括：获取生猪的身份信息；获取当前位置对应的目标三维猪体图像，以及生猪测定站的图像数据；将所述目标三维猪体图像和所述生猪测定站的图像数据输入至预
