[0039] The present invention is a real-time risk prediction method based on 3D vision, such as figure 1 shown, including:

[0040] Step 1: Collect video images of the monitored object and its surrounding environment in real time, and establish an image database. Wherein, the video images of the monitored object and the surrounding environment can be collected by a video collection device, for example, video images are collected by using a camera, radar, scanner, etc. The image database includes at least one video image.

[0041] Step 2: Extract feature data of all video images in the image database in step 1, such as tilt angle features, distance features, etc.; establish a feature database based on the extracted feature data. The feature database includes at least two data types: the morphological feature of the monitored object and the interaction feature between the monitored object and the surrounding environment.

[0042] Step 3: Process the feature data in the feature...

Description

technical field [0001] The present invention relates to the technical field of risk prediction, in particular to a real-time risk prediction method and system based on 3D vision. Background technique [0002] Predicting the future trajectory and potential safety hazards of the monitored object in advance has received extensive attention in the field of risk prediction technology, and plays a very important role in real life, such as fall prediction and evaluation, child bump prediction, traffic accident prediction Wait for the scene. It is necessary to estimate potential risks that have not yet occurred in the future based on previous scenarios in real time, and to protect in advance based on the risk prediction value. Therefore, how to accurately predict future scenarios and accurately model and predict future scenarios is crucial. [0003] In recent years, with the maturity of artificial intelligence and smart devices, how to better use artificial intelligence technology...
