[0043] Example 1
[0044] The present invention includes the following steps:
[0045] S1. Collect the gesture video in the cockpit and preprocess it to obtain a static gesture image;
[0046] S2. Perform segmentation processing on the gesture and background in the gesture image to obtain a gesture area image;
[0047] S3. Multi-granularity expression of the gesture region image from coarse-grained to fine-grained; using convolutional neural network to extract multi-granularity features of the gesture region image;
[0048] S4. From coarse-grained to fine-grained, calculate the conditional probability of each granularity of the gesture area image classification to each category, and use three decisions to complete the gesture recognition sequentially;
[0049] S5. Perform semantic conversion on the recognized gesture region image, and operate the human-computer interaction interface according to the gesture recognition result after semantic conversion;
[0050] The multi-granularity expre...

[0076] Example 2
[0077] On the basis of steps S1 to S5, this embodiment also adds step S6 to obtain the optimal granularity by means of weighted summation, using the optimal granularity as the finest granularity, and repeating steps S3 to S5.
[0078] HMI interface optimization design methods such as Figure 4 As shown, the weighted summation method is used to obtain the final human-computer interaction interface optimization results of each granularity, so as to determine the optimal granularity of the gesture area image. The optimal granularity is used as the finest granularity, and the convolutional neural network is used for the new gesture Extract multi-granularity features and make three decisions sequentially;
[0079] Result=w×Acc+(1-w)×Time
[0080] Time=T 1 +T 2
[0081] Among them, Result is the best granularity of the gesture area image, Acc represents the accuracy of gesture recognition, Time represents the time spent in the gesture recognition process, w represents the...
