The evaluation of body size parameters and morphology based on body size parameters can reflect the growth and development characteristics, production performance and genetic characteristics of sheep. Therefore, studying the measurement of body size parameters and morphological evaluation is an effective way to determine the reasonable breeding of sheep farms and improve the breeding efficiency. In the measurement of human body size based on machine vision, the change of posture has a great influence on the human body size parameters. In this paper, a segmentation algorithm of sheep head, body and legs based on the sheep contour is proposed. Through this algorithm, five posture features are extracted, which are the angle between the hip point and the lower right corner coordinate of the head, the angle between the hip point and the lower left corner coordinate of the head, the angle between the lower right corner coordinate of the body and the lower right corner coordinate of the head, the angle between the lower right corner coordinate of the body and the upper left corner coordinate of the head and the length-width ratio of the circumscribed rectangle. The test results show that the accuracy of the program compiled by the hierarchical vector machine algorithm reaches 95.68%.
