In a dynamic scene, false detection is easy to occur through a video image detection processing result in actual detection due to light change and complex and changeable background. In order to reduce the false detection probability, the embodiment adopts a framework of a three-classifier cascade fusion algorithm.

As shown in fig. 3, the architecture algorithm inputs the collected images into a feature extraction network, performs feature extraction to obtain a detection feature spectrum, adds a new classifier after two original classifiers, and adds corresponding loss classifications for training. The new classifier has the same loss number as the original classifier, and the new classifier uses the samples incorrectly classified by the original classifier as training samples, so that the new classifier is better in distinguishing the samples incorrectly classified, and the classification accuracy can be improved.

After training the multiple classifiers, fusing and comparing the results of the multiple classifiers to obtain a final result, wherein the final result is shown in the following formula:

wherein, the liquid crystal display device comprises a liquid crystal display device,confidence indicating that the final prediction result is of class y, < >>Indicating the confidence that the jth classifier predicts belonging to class y. />Representing the ith image sample entering the jth classifier, m representing a total of m image samples entering the jth classifier,/v>Representing the weight corresponding to the ith image sample,/->And the loss parameter corresponding to the j-th classifier is represented.

Example seven

According to the intelligent door and window control method, the intelligent window has an intelligent anti-clamping function when the window is opened and closed. Because the current difference between the alternating current motor during rotation and the current difference during normal operation is small, whether the external force blocks the rotation of the window alternating current motor cannot be judged through the current difference of the alternating current motor. Then, when the direct current motor stops rotating due to external resistance, the current of the direct current motor can be rapidly increased, compared with the current which works normally, the intelligent door and window is driven by the direct current motor, judgment of anti-clamping operation is carried out by detecting the current of the direct current motor, and the direct current motor is suspended when the anti-clamping operation is adopted, so that safety is protected, and dangerous situations are reduced.

The external resistance and the motor current of the intelligent window motor have the following relation:wherein->Is external resistance (I/O)>For motor current +.>Is a proportional coefficient->Is the electromotive force constant of the direct current motor, < > >For the magnetic moment of inertia of the motor, < >>For the motor to be subjected to an equivalent resistance coefficient,is the equivalent resistance of the direct current motor, < >>For Laplace operator>Inductive inductance for the magnetic field of the motor, < >>In order for the moment of inertia to be of interest,for the current during motor operation, < >>And for correcting the coefficient, the external resistance of the intelligent window motor is obtained by detecting the current, and when the external resistance is greater than a threshold value, the anti-pinch action is adopted to pause the window opening and closing action.

The intelligent door and window control method can judge whether the window is required to be opened or closed by taking the anti-pinch action by detecting the current to obtain the external resistance of the window, so that the safety is protected, and the risks that hands, first ends and the like extend out to be pinched and the like are prevented in the window opening and closing process of a user.

Example eight

In the intelligent door and window control method, after the video image is acquired by the door and window camera, the door and window controller performs video analysis processing on the video image, and the intelligent door and window is controlled according to the processing result. In a dynamic scene, false detection is easy to occur in the actual video image detection processing result due to light change and complex and changeable background. In order to reduce the false detection probability, the embodiment adopts a framework of a three-classifier cascade fusion algorithm.
