The invention relates to the technical field of smart tourism, in particular to a personalized scenic spot content generation method, system and device based on a multi-modal knowledge graph and a medium, and the method comprises the steps: collecting multi-modal data of a scenic spot, and constructing a structured multi-modal scenic spot knowledge graph based on the multi-modal data; obtaining personalized data provided by the tourist, and constructing a personalized portrait of the tourist based on the personalized data; in response to an operation of acquiring an image in a scenic spot, identifying the scenery in the image, and extracting a corresponding initial knowledge subset from the multi-modal scenic spot knowledge graph according to an identification result; performing personalized screening and expansion on the knowledge nodes in the initial knowledge subset by calculating the matching degree between the knowledge nodes in the initial knowledge subset and the tourist interest in the personalized portrait of the tourist, and dynamically binding multi-modal resources to generate a personalized knowledge graph; and presenting the personalized knowledge graph. According to the invention, the multi-mode scenic spot knowledge experience of which the structure is matched with the interest and the knowledge background can be provided for tourists.

The application provides an automatic driving visual perception feature extraction method and device, raw images are collected based on multiple camera sensors around a vehicle body, and the surrounding space is divided into multiple voxel units with the vehicle body as the center; a raw image feature map of raw image features extracted by a backbone network is constructed, a preset attention module containing a time sequence attention module and a space attention module is constructed, each voxel is taken as a basic prediction unit, past multi-time features are fused through the time sequence attention module, features of the raw image feature map mapped on voxels in a three-dimensional space are mined through the space attention module, features in the 3D space are recovered from the 2D image, memories of multiple time points are fused, and spatial features with better representation ability are mined to meet learning requirements of downstream tasks of automatic driving.

The invention provides a courseware recommendation method, device and system. The courseware recommendation method comprises the following steps: acquiring a personalized data information file of a user and a courseware content management model; performing content matching according to the user personalized data information file and the courseware content management model; and recommending the content matched with the courseware content management model to the user. Through real-time matching of user personalized data information archives and courseware contents, real-time analysis of knowledge mastering conditions, skill improvement conditions, emotional attitudes and the like of users is realized to dynamically adjust learning paths and recommendation resources, and the utilization efficiency of teaching resources and the teaching effect are improved; besides, by integrating virtual reality (VR), augmented reality (AR) and other multimedia technologies, an immersive learning scene is constructed, and effective integration of the technologies and deep fusion with teaching are promoted.

The application discloses a teaching interaction method and device, electronic equipment and computer storage medium. The method comprises the following steps: receiving an online class listening request sent by a student end; in response to the online class listening request, verifying whether a student corresponding to the student end is currently in a leave state; if the student corresponding to the student end is currently in the leave state, confirming that the online class listening request is verified; under the condition that the online class listening request is verified, allowing the student end to join an online classroom currently opened by a teacher end; the online classroom is used for displaying offline course videos received by the teacher end. In this way, students who can listen to offline classes can also use the student end to listen to online classes, so that they do not pay attention to offline classes due to excessive dependence on online teaching videos, and the learning needs of students who cannot listen to offline classes can be met, so that they can learn offline teaching content through the student end and classmates learning offline.
