The invention discloses a rat condition monitoring method, a device, a processor and a storage medium. The method comprises the following steps of: acquiring an image of a predetermined place from animage acquisition device; and based on the convolution neural network computational model, the image is analyzed to generate the information about the existence of rodent emotion in the preset place.Thus, the technical solution of the embodiment solves the technical problem of poor stability existing in the prior art, which can not realize the operation in the mobile terminal or embedded device.
