Abstract：Growth performance measurement is an important part of pig breeding work,and the indicators for evaluating pig growth performance include body size and body weight.A large amount of regular body size measurement and specific nurturing period body weight measurement are carried out in actual breeding process.At present,body size measurement mainly relies on manual measurement,which is time-consuming and laborious,low efficiency and with many subjective errors.And manual measurement restricts the auxiliary role of phenotypic traits in breeding and production management.Computer vision technology has become the fastest developing research field in assisting automatic determination of phenotypic and body size traits in livestock.Considering the development status and measurement positioning errors of 3D vision technology in pig body measurement,this paper proposes the 3D point cloud segmentation technology for pig body size measurement,that achieving precise positioning and improving the accuracy of automatic body measurement by dividing the pig body point cloud into different parts.
