Automatic feeding control method and system for waste incineration feeding

The invention relates to an automatic feeding control method and system for waste incineration feeding. The method comprises the steps of acquiring an image of a waste feeding port in real time, and acquiring the depth information of an imaging plane; carrying out Gaussian mixture model background modeling according to the depth information; carrying out three-dimensional reconstruction accordingto the Gaussian mixture model background modeling to calculate the volume of waste; and judging whether feeding needs to be carried out or not according to the volume of the waste. The system comprises a depth sensor platform, a depth sensor and a processor. The depth sensor is connected with the processor, the depth sensor is arranged on the depth sensor platform, the detection surface of the depth sensor covers the feeding port, and the processor is further connected with a reamer of a waste incineration device. The system has the advantages that the volume of the waste at the feeding port is monitored in the whole
