Abstract: With continuously extending of pig breeding scale and quantity in China, husbandry informatization will be an important supervise model for pig breeding industry at present and in the future. As an effective support technology for information processing, computer vision technology has provided a behavior recognition method with automatic, non-contact, low-cost, high profit and yet non-injury and non-stress for animals. It is capable for assessing pig health condition, timely preventing and diagnosing diseases. This paper introduced pig behavior recognition vision system; reviewed the application of vision technology in pig target extraction and individual recognition, behavior recognition analysis, and algorithm; and analyzed the existing problems in accuracy, effectiveness and applicability of existing visual system and behavior recognition method. Before ending, the paper put forward several strategy for improving visual system, and key research direction for applying computer vision technology in pig individual and behavior recognition.
