In-vehicle key operating system based on image recognition

Abstract

The invention discloses an in-vehicle key operating system based on image recognition, which comprises a high pixel camera, an image recognition processing unit, an ambient light sensor unit, a cameraauxiliary illumination unit, a key recognition unit and a key backlight indication unit, wherein the high pixel camera completely covers the key recognition unit; the high pixel camera acquires an image of the key recognition unit; the image recognition processing unit processes an image signal from the high pixel camera; the ambient light sensor unit measures the visible light intensity; the camera auxiliary illumination unit provides fill-in light for the high pixel camera; the key backlight indication unit provides back lighting for the key recognition unit. The in-vehicle key operating system based on image recognition in the invention adopts a high pixel camera to collect the image of the key operation in the vehicle; after the image is processed through the image recognition processing unit, a corresponding key control signal is output to the body controller through a CAN bus, thereby effectively improving the flexibility and simplicity of the key operation in the vehicle and achieving the advantage that mechanical keys are incomparable.

Description

technical field [0001] The invention relates to the field of button operation inside a car, in particular to a button operating system in a car based on image recognition. Background technique [0002] At present, there are more and more electronic control units inside the car, and the corresponding number of key inputs is also increasing. Therefore, as a traditional input terminal, mechanical buttons cannot fully meet the needs of the current key input development in the car, especially the interior decoration requirements are more beautiful, and the curved surface shape is more complex and rich. [0003] Using mechanical buttons in the car has the following disadvantages: [0004] (1) Due to the influence of the use environment in the car, the service life of the mechanical key is short and the operation reliability is low. [0005] (2) The number of mechanical keys set in a limited space is also very limited, and even mechanical keys cannot be set due to space constrain...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the influence of the environment in the car, the service life of the mechanical buttons is short and the operation reliability is low

[0005] (2) The number of mechanical buttons set in a limited space is also very limited, and even mechanical buttons cannot be set due to space constraints

[0006] (3) Mechanical buttons can only be placed in applications with regular shapes and flat surfaces, and cannot be used on curved surfaces or special-shaped surfaces

[0007] The above shortcomings have a great degree of limitation on the operation of mechanical buttons in the car, so it is necessary to innovate it to overcome these shortcomings
