Most existing conventional object detection algorithms are based on sliding windows and artificial feature extraction,and exhibit disadvantages such as high computational complexity and unsatisfactory robustness under complex conditions. Recently,deep learning has been applied to object detection,bringing significant improvements to algorithm performance. Compared with conventional target detection algorithms,deep-learning-based algorithms offer high speed,accuracy and robustness under complex conditions.In this paper,we first expound upon target detection tasks in terms of their evaluation indicators,public datasets,and traditional algorithm frameworks. Then the existing deep learning-based target detection algorithms are categorized based on two criteria,whether there is an explicit region proposal and whether to define a priori anchorbox. We introduce the evolution of these algorithms,summarizing their mechanism,advantages,limits and application scenarios. On this basis,the performance of the representative algorithmson public datasets are analyzed and compared. Finally,we discuss the future directionsofresearch in deeplearning-based object detection.
