Objective:Using point-cloud processing technology,the 3D model of live pigs was reconstructed,which provided necessary conditions for the research of automatic body size measurement and weight estimation of live pigs in the later stage,reduced the risk of disease transmission and stress reaction caused by manual measurement,and reduced the economic loss of pig farms.Methods:The multi-view video data acquisition platform was developed to realize the simultaneous acquisition of video data from different angles by two depth cameras,and the point-cloud data of two perspectives was obtained after processing.The 3D model of live pigs was reconstructed by studying the accurate matching technology of point-cloud images.Results:The accurate and complete 3D model of live pigs could be generated by the fine registration of the point-cloud image of live pigs,and the body size measurement results were improved by 0.6％compared with the coarse registration of the 3D model.Conclusion:3D pig model provided an efficient and non-contact solution for body size measurement in the later stage of live pigs,which had broad application prospects and potential practical value.
