Region detection method, system and device of mobile robot and medium

The invention discloses an area detection method, system and device of a mobile robot and a medium. The method comprises the steps of obtaining image data; the image data is recognized and analyzed through a multi-task neural network model, a target drivable area of the mobile robot is obtained, and the multi-task neural network model is obtained through training of the following steps that a multi-class data set is obtained and labeled, a labeled data set is obtained and input into a first-level network framework for training, and a first-level network framework is obtained; outputting the first data set and the second data set; inputting the second data set into a secondary network framework to obtain a third data set; and performing multivariate fusion on the first data set, the third data set and the radar interface data to obtain a fused data set, and updating parameters of the multi-task neural network model according to the fused data set to obtain the multi-task neural network model.
