Problems solved by technology
Therefore, the range of gesture interaction recognition needs to be considered comprehensively. At present, the existing image recognition field usually has a fixed recognition range, that is, a recognition frame is usually set. The complex environment in the car and the recognition requirements in different driving situations, this fixed recognition mode is actually not suitable for gesture recognition in the car

The present invention relates to the technical field of automobile control methods, in particular to an automobile gesture interaction method. Use the control system to segment the image area for gesture recognition by the camera, and divide the image area into a recognized area and an unrecognized area; recognize the gestures that appear in the recognized area, and obtain the confidence of the gesture image that appears in the gesture detection frame; Collect the current vehicle speed to obtain the confidence threshold of gesture recognition under the current vehicle speed. The confidence threshold is a set value whose value is smaller when the vehicle speed is higher; compare the confidence degree with the confidence threshold. If the confidence degree ≤ the confidence threshold, then the corresponding gesture image The gesture is judged as an invalid gesture; if the confidence degree>the confidence threshold, the gesture corresponding to the gesture image is judged as a valid gesture, and the control system recognizes the valid gesture to judge the driver's intention. The identification method of the present invention is extremely simple, and different identification measures are adopted for different scenes, so that the adaptability and accuracy are better.
Description
technical field [0001] The present invention relates to the technical field of automobile control methods, in particular to an automobile gesture interaction method. Background technique [0002] With the development of automotive electronic technology, more and more electronic devices are integrated in the car cockpit, all of which need to be controlled by the driver. Traditional mechanical switches are no longer sufficient for use, and new interactive technologies such as touch screens, voice interaction, and gesture interaction have emerged. Among them, the gesture interaction technology uses various sensors to capture the driver's hand movements, recognizes them through algorithms and drives functional applications. [0003] General gesture interaction technology requires the recognition range to be as large as possible, but it is not fully applicable to automotive gesture interaction. On the one hand, the space inside the car is limited and there are various parts and...
