Embodiment Construction
[0042] Refer to attached Figure 1-2 , the embodiments of the present invention will be described in detail.
[0043] A method for analyzing an abnormal trajectory based on an adjoint model, comprising the following steps:
[0044] Step 1: The video structured system performs face recognition, obtains face video data and performs preprocessing;
[0045]Step 2: Preset the risk threshold of the accompanying personnel, and then carry out accompanying analysis and mining on the accompanying personnel through the frequent model mining algorithm to obtain the accompanying relationship data and accompanying risk coefficient. If the accompanying risk coefficient is greater than the accompanying personnel risk threshold, record it as a risk accompanying person;
[0046] Step 3: Use the unsupervised learning algorithm to detect the abnormal trajectory of the accompanying relationship data of the risk accompanying personnel, and obtain the abnormal trajectory of the risk accompanying pe...
