Region detection method and related device, equipment and medium thereof

The invention discloses a region detection method, a related device, equipment and a medium. The method comprises the following steps: acquiring a to-be-detected image; performing region detection on the to-be-detected image by using the region detection model to obtain a target prediction box about a specific text region in the to-be-detected image; wherein the region detection model is obtained through optimization based on an evaluation index of the region detection model, the evaluation index is obtained based on the boundary closeness degree between a true value box and a prediction box of a specific text region in the verification sample image, and the prediction box is obtained through region detection of the verification sample image by the region detection model. In this way, the accuracy of the target prediction frame can be improved. 本申请公开了一种区域检测方法及其相关装置、设备和介质，该方法包括：获取待检测图像；利用区域检测模型对待检测图像进行区域检测，得到待检测图像中关于特定文本区域的目标预测框；其中，区域检测模型是基于区域检测模型的评估指标进行优化得到的，评估指标是基于验证样本图像中的特定文本区域的真值框与预测框之间的边界紧密程度得到的，预测框是区域检测模
