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 invention relates to the technical field of automobile control methods, in particular to an automobile gesture interaction method. The method comprises the following steps: performing segmentation processing on an image region for gesture recognition of a camera by using a control system, and dividing the image region into a recognition region and a non-recognition region; identifying the gesture appearing in the identification area, and obtaining the confidence coefficient of the gesture image appearing in the gesture detection frame; acquiring a current vehicle speed to obtain a confidence threshold value of gesture recognition at the current vehicle speed, wherein the confidence threshold value is a set value of which the value is smaller when the vehicle speed is higher; comparing the confidence coefficient with a confidence threshold value, and if the confidence coefficient is smaller than or equal to the confidence threshold value, judging the gesture corresponding to the gesture image as an invalid gesture; if the confidence coefficient is larger than the confidence threshold value, judging the gesture corresponding to the gesture image as an effective gesture, and the control system recognizes the effective gesture to judge the intention of the driver. The recognition method is extremely simple, different recognition measures are adopted for different scenes, and 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...
