| Summary: | In order to improve the detection accuracy of SSD (Single Shot MultiBox Detector), an A-SSD (Anchor-object SSD) object detection algorithm based on Anchor-object matching is proposed. In the feature extraction part of the algorithm, parallel convolution and hole convolution are used to form the receptive field module, which increases the receptive field of the feature map and obtains multi-scale feature information, combining the shallow features containing texture, edge and other detailed information with rich fusion of deep features of semantic information. In the detector part of the algorithm, the Anchor-object matching method combined with the SSD multi-layer feature map is used to construct the corresponding Anchor package for each detection target. Through the selection-suppression optimization strategy, the Anchor with higher confidence is selected to update the model. Anchor evaluation score, in continuous iterative learning, the model parameters, Anchor position coordinates and classification confidence are continuously optimized. The mAP of the A-SSD algorithm on the PASCAL VOC data set reached 80.7, and the missed detection rate of the A-SSD algorithm on the workshop pedestrian data set was 3.5%, and the accuracy rate was 91.5%. |
