Abstract

The present invention discloses a vehicle device based on infrared-sensing gesture recognition. By the combination of infrared sensing, Zigbee positioning and microwave displacement sensing, the vehicle device provides convenience for a user to perform function control on a terminal. According to the ivehicle device based on infrared-sensing gesture recognition related to the present invention, accuracy of an infrared sensing gesture recognition technology is improved and probability of incorrect operations is reduced; and a driver just needs a simple operation without any need to lean or bend his body to implement function control on the terminal, so that hidden driving troubles are avoided, and wide application prospects in the field of vehicle smart devices is ensured.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to a vehicle-mounted device based on infrared induction gesture recognition, and belongs to the field of vehicle-mounted intelligent devices. Background technique [0002] During the driving process of the car, the driver often needs to perform operations such as multimedia volume adjustment, song selection, and channel change, while the center console or bracket equipment requires the driver to operate sideways or leaning over, which poses a great hidden danger to driving safety. There are defects such as inaccurate function realization or cumbersome operation of infrared gesture recognition technology. [0003] Chinese patent CN104298348 discloses an infrared gesture recognizer, including: a transmitter emitting infrared light, an infrared receiver for receiving infrared light reflected back by the user's palm, and an infrared receiver for receiving the infrared light reflected from the...
