Training method and device of target detection model

The invention provides a training method and device of a target detection model. The training method of the target detection model comprises the steps of obtaining a first training image; inputting the first training image into a candidate region detection model to obtain first candidate region information corresponding to the first training image; inputting the first training image and the first candidate region information to the target detection model to be trained for training to obtain an initial target detection model; obtaining a second training image and second candidate region information corresponding to the second training image; and inputting the second training image and the second candidate region information into the initial target detection model for continuous training to obtain a target detection model. Through the method, the cost of labeling the sample data is reduced, the accuracy of target detection is improved, and the training speed of the model is increased. 本申请提供一种目标检测模型的训练方法及装置，其中所述
