The invention provides a method for constructing a dense small target detection model, the model and the detection method. Based on the information fusion of the target midpoint context, through cutting the picture with high resolution, the method avoids the picture sampled under the input network from losing too much image information, and affects the network feature extraction. The residual pyramid feature extraction network is used to fuse the features of different scales, which improves the detection accuracy of the network for different size targets, especially for small targets. A RoIAlign layer instead of RoIPooling layer is used to solve the position deviation of candidate frames caused by feature mismatch of candidate regions. Because the small target features are easily lost in the network transmission, the center point context features are fused with the original RoI features, so that the network can make full use of the target context information, ensure the network runningspeed, more accurately locate and identify the dense small target, and improve the network performance.
