The invention relates to a target detection method, a storage medium and computer equipment. According to the invention, on the basis of carrying out first detection on image features of different hierarchies, the cavity convolution processing is carried out, the target detection is carried out on the processed features again according to the first detection result, and the cavity convolution processing can improve the receptive field of the low-level features, thereby improving the detection capability of the small target in the image, and improving the accuracy of the detection result of thesmall target in the image.
