Abstract
A device of employing hand gesture recognition technology to control a vehicle electric appliance comprises camera equipment (10), a hand gesture recognition module (20), a micro-processor MCU and a memory (30) all arranged in a vehicle cab and connected in sequence; the memory is connected with the hand gesture recognition module; the micro-processor MCU is connected with a control system of the vehicle electric appliance. The camera equipment shoots and records instruction hand gestures of a driver; the hand gesture signal is compared with a hand gesture template signal stored in the memory in advance, and an instruction represented by the hand gesture is decided; the instruction is sent to the micro-processor, and the micro-processor can control the vehicle electric appliance to execute corresponding motions. The device and method introduce the hand gesture recognition technology in the vehicle electric appliance control technology, so attention deficit caused by button operation of the driver can be prevented, thereby ensuring driving safety.
Description
Technical field
The present invention relates to control technology, particularly utilize gesture to control the device and method of car electrics.
Background technology
In prior art, car electrics are all generally adopt by key control or adopt voice control etc., but, all there is certain drawback in these two kinds of control methods, first, button control mode is because needs driver and crew free hand to control, particularly automobile DVD and car light control knob, major part is all on console, distant from bearing circle, and generally these control actions are all that driver completes, so, utilize by key control driving safety produced and compares considerable influence.And voice are controlled due to more noisy in car, easily cause erroneous judgement, affect the normal use of equipment.Gesture Recognition has obtained development greatly at present, and this technology has extraordinary supplementing for solving above-mentioned two kinds of existing drawbacks of control mode, but, up to now, also by automobile industry personage, be not familiar with, be not applied in the middle of car electrics control, so utilizing gesture to control car electrics becomes imperative trend yet.
Summary of the invention
Provided by the invention this utilize device that gesture controls car electrics with and application on automobile, adopt ripe Gesture Recognition, the technical matters of controlling inconvenience and easily causing security incident for solving prior art car electrics.
The present invention is arranged on car steering picture pick-up device, gesture identification module, Micro-processor MCV indoor and that connect successively and the storer that connects described gesture identification module for the device that provide this is provided utilizes Gesture Recognition to control car electrics comprises, described Micro-processor MCV connects the control system of car electrics.Described gesture identification module comprises A/D analog-to-digital conversion module or image comparison module.
This Gesture Recognition comprises the following steps at the application process aspect car electrics control: A. installs picture pick-up device on automobile, driver and conductor's order gesture is recorded in shooting, and the mode that picture pick-up device adopts that touching switch wakes up, certain gestures is waken up, ignition switch or voice wake up starts; B. hand signal and pre-stored gesture template signal in storer are compared, be stored in storer is that gesture template signal is picture signal or digital signal, images of gestures and this gesture template image signal that picture pick-up device is captured compare, or after the captured images of gestures of picture pick-up device is converted to digital signal, compare with gesture template digital signal again, judge the instruction of this hand signal representative; C. this instruction is sent in microprocessor, by microprocessor, control car electrics and carry out corresponding action.
The present invention adopts above-mentioned technical scheme, Gesture Recognition is referred in car electrics control technology, that can avoid that driver's operation button causes is absent minded, guarantee traffic safety, also avoid voice control technology in noisy environment, to be not easy the problem of identification, practicable control program is provided.
Accompanying drawing explanation
Fig. 1 is the theory diagram of invention car electrics gesture control device.
Embodiment
1 specific embodiments of the invention are described by reference to the accompanying drawings.
Known in Fig. 1, this device that utilizes Gesture Recognition to control car electrics comprises and is arranged on car steering picture pick-up device 10, gesture identification module 20, Micro-processor MCV indoor and that connect successively and the storer 30 that connects described gesture identification module 20, and described Micro-processor MCV connects the control system of car electrics.
Described gesture identification module 20 comprises A/D analog-to-digital conversion module 21, or described gesture identification module 20 comprises image comparison module 22.
And this Gesture Recognition comprises the following steps at the application process aspect car electrics control: A. installs picture pick-up device on automobile, driver and conductor's order gesture is recorded in shooting, and the mode that picture pick-up device adopts that touching switch wakes up, certain gestures is waken up, ignition switch or voice wake up starts; B. hand signal and pre-stored gesture template signal in storer are compared, judge the instruction of this hand signal representative; C. this instruction is sent in microprocessor, by microprocessor, control car electrics and carry out corresponding action.
The present invention adopts Gesture Recognition to control car electrics, when needs control apparatus moves, as long as driver makes the gesture of a regulation, car electrics just can move according to driver's gesture, can control automobile DVD equipment, navigator, radio and car light etc.
When pre-stored in storer, be gesture template signal while being picture signal, images of gestures and this gesture template image signal that picture pick-up device is captured compare.When pre-stored in storer, be gesture template signal while being digital signal, the images of gestures that picture pick-up device is captured is converted to digital signal, then compares with gesture template digital signal.Take in advance some standard gestures and be stored in storer, and the operational order of this gesture and car electrics is bound, gesture in captured images of gestures and standard form is contrasted, thereby assert and whether carry out instruction etc.
In steps A, picture pick-up device adopts the mode that touching switch wakes up or voice wake up to start, in steps A, picture pick-up device adopts the gesture motion that continues to take driver and conductor, in step B when gesture motion signal matches with gesture template signal or when close, step C just controls car electrics action, when the degree of approximation of gesture motion signal and gesture template signal reach 80% or more than, assert that this gesture motion signal is clear and definite instruction.This patent has also designed the scheme of fuzzy identification, because everyone gesture motion is not necessarily consistent, therefore, adopt very strict identification measure not necessarily can reach effect well, in this patent, think, when action has eighty per cant when close, just can assert and give clear and definite steering order.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
