Embodiment Construction
[0043] The technical solution of the present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation methods. A smoke video detection algorithm based on the improved MobileNetV2-SSD model, said method improves the detection rate of small smoke targets based on the novel reconstruction pyramid model, based on the feature enhancement suppression mechanism of the SE-Net module, the method of the present invention comprises the following steps:
[0044] S1. Optimize the SSD target detection framework to obtain the MobilenetV2-SSD model;
[0045] S2. On the MobilenetV2-SSD target detection framework, perform a pyramid feature map reconstruction operation on it;
[0046] S3. Set the default candidate frame parameters of each feature layer of the model according to the prior characteristics of the smoke;
[0047] S4, embed the SE-Net module behind the six feature layers to obtain an improved MobilenetV2-SSD model;
[0048] ...
