However, due to the long distance, the gesture recognition rate is easily affected by the weather. , lighting, viewing angle, the recognition rate is low, and it needs to occupy the resources of the processor in the TV host; the other is to use the gesture recognition module built in the remote control to perform feature extraction and recognition of user gestures, the gesture recognition module and the controller Connected, the controller is connected to the signal transmitter, and the TV body is equipped with a signal receiver and a processor to achieve gesture recognition control. This type avoids some of the previous category and improves a certain recognition rate, but the image processing algorithm The cost of energy consumption will greatly reduce the use time of the remote control, and the image quality is also affected by the weather and light. The high or low cost of the camera determines the quality of the image, which affects the cost and recognition rate.
