| Abstract: |
| In order to detect common pedestrians and vehicles, a self-annotated dataset was introduced and an optimized algorithm was proposed based on the faster RCNN （region-based convolutional neural network）[1] framework for parameter tuning in this paper. The lightweight MobileNetv2 was utilized as the backbone network, and two additional area scales were added to the region proposal network（RPN）on top of the original anchor boxes. The ROI Align structure was employed in the detection part to reduce errors in feature mapping and pooling process. Experimental results showed that by using the faster RCNN object detection network pedestrian and vehicle detection tasks could effectively accomplished with overall good performance. |
