Based on binocular vision technology,a target detection and ranging technology suitable for unmanned feeding equipment is studied.A high-precision target detection and recognition and binocular ranging method was designed,and related simulation experiments were carried out.The experimental results show that the average accuracy of the improved recognition and positioning algorithm is 99.53%.When the binocular camera is 40 cm to 90 cm away from the feeding device,the relative error of ranging is between 0.59% and 1.26%,which can effectively assist the short-distance positioning feeding device.It better meets the docking function requirements of the feeding device and the silo,and has positive significance for enhancing the automation level of the feeding device.
