Vehicle navigation system and gesture operation method thereof

Abstract

The present invention discloses a vehicle navigation system. The system comprises a navigation module, a Bluetooth module, a SIM communication module, a sound collection module and an intelligent monitoring module, which are used for communicating with a remote terminal and transmitting navigation driving state information; a voice identification module and a gesture determination module, which are used for identifying gesture information of three fingers of the driver and activating the corresponding function module according to the gesture information; and a control information calculation module, which is used for calculating and comparing voice control information identified by the voice identification module and gesture control information acquired by the gesture determination module,and transmitting a comparison result to the central processing unit. According to the technical scheme of the present invention, by combining the voice and the gesture, the control instruction can beaccurately identified in the non-visual situation, the defect of poor accuracy when the voice or the gesture is separately identified is avoided, and without distracting the line of sight of the driver, the safe driving experience of the car navigation system is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a vehicle navigation system and a gesture operation method thereof. Background technique [0002] With the development of electronic information technology, the car navigation system has become an indispensable configuration in the car. The current car navigation system is composed of a touch screen and operation buttons. This operation method will distract the driver's attention and is not conducive to safe driving. Therefore, a series of gesture-controlled navigation systems have appeared on the market. These gesture-controlled navigation systems use infrared light to scan the size, shape, palm and fingers of the hand. The length-to-width ratio, the natural angle of finger separation, and the natural angle of palm bending are used to identify data. However, the above-mentioned gesture recognition technology requires additional high-cost software and hardware support...

However, the above-mentioned gesture recognition technology requires additional high-cost software and hardware support, and the recognition process has a certain response delay, which usually can reach tens of milliseconds to several seconds; moreover, the gesture recognition and the detection of the number of fingers are not accurate enough. A large number of software processing and algorithm implementation, and the recognized gesture features are limited, which cannot be integrated with various functions of the navigation system, and the control efficiency of the navigation system is low
