[0027] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Such as figure 1 with 2 As shown, the present invention provides a crowd density estimation method, which includes:
[0029] Step S1: Construct a corresponding truth map according to the corresponding crowd position coordinates given by the crowd image data set with a density greater than a preset threshold, train the AlexNet network for image classification, and train the feature network of the fusion attention mechanism under dense conditions. Training the feature network of fusion hole convolution in the sparse case;
[0030] Step S2: Build the AlexNet network, the feature network integrated with the attention mechanism, and the feature network integrated with the hollow convolution into a final training network wi...
