Abstract: Based on machine learning algorithm, an intelligent method and monitoring system for individual identification of rodents in the nighttime environment are studied. According to the SSD target detection algorithm, the rat individual identification model was designed and optimized; the low-light night vision monitoring system was built to carry out the imaging monitoring experiment of the rat individual in the weak light environment. The experimental results show that under the given conditions for different mouse individual targets, the average accuracy rate of the optimized mouse individual intelligent recognition model can reach 98.14%, and the average recall rate is 98.62%. It shows that the researched intelligent identification method and monitoring system can be used for further research on rodent individual identification and behavior monitoring methods under night vision conditions.
