Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, a flowchart illustrating steps of a window color control method according to an embodiment of the present invention is shown, where the window color control method may include:
step 101, acquiring a first gesture image of a user by a gesture recognition sensor;
the gesture recognition sensor is equipment for processing gesture actions of a user through induction, and the gesture recognition sensor can be arranged at the position of a door guard plate of an automobile, so that the gesture recognition sensor can conveniently acquire gesture images of the user, and the user can conveniently observe the color change condition of a car window.
The gesture recognition sensor in the invention is a recognition technology based on two-dimensional images. The user makes a first gesture motion within the sensing distance of the gesture recognition sensor, and a built-in camera shoots the gesture motion of the user to obtain a sequence formed by two-dimensional gesture images, so that the dynamic gesture motion is converted into a static gesture image sequence, and the gesture image sequence is the collected first gesture image of the user.
It should be noted that, because the gesture recognition sensor based on the two-dimensional image can recognize several gesture actions, the gesture actions are preset in advance. For example: the first gesture motion can be a preset motion that the user's finger slides from top to bottom or from bottom to top in the air, and then the corresponding motion acquired by the gesture recognition sensor is an image sequence that the user's finger slides from top to bottom or an image sequence that the user's finger slides from bottom to top in the air.
It should be noted that the examples of the gesture actions and the specific instruction meanings represented by the gesture actions herein are only for explaining the technical solutions of the present invention, and do not constitute a limitation to the present invention, and those skilled in the art can reasonably change and expand the gesture actions and the meanings thereof, and all of them are within the scope of the present invention.
102, acquiring a first control instruction corresponding to the first gesture image by the gesture recognition sensor according to a relation between a preset gesture image and the control instruction;
because the gesture recognition sensor converts the gesture motion into a gesture image sequence, the two-dimensional gesture recognition has dynamic characteristics, and therefore the gesture recognition sensor based on the two-dimensional image can track the motion track of the gesture.
Dynamic gestures are characterized by the spatiotemporal characteristics of their motion patterns, and in the prior art, there are two main categories of common methods for dynamic gesture spatiotemporal trajectory analysis: a track template matching method and a state space modeling method. The trajectory module matching is a method for making behavior judgment based on a trajectory of a moving part, and a typical template matching method is Dynamic Time-warping (DTW) which integrates the regular amount of a gesture motion trajectory and the type of a gesture into a uniform state object, and takes a trajectory to be recognized as an observed quantity to find an optimal state estimation based on a current observation trajectory. This method can be seen as comparing the observed trajectory with a local linear template of fixed length to obtain the best recognition result. The state space modeling method is used for modeling the space-time characteristics of the gesture track in a state space. The motion trajectory of a gesture can be viewed as a series of transitions between states. And (3) state space modeling, namely learning the parameters of state conversion from the training track samples, and comparing the observation track with different gesture model samples to obtain a recognition result.
The gesture recognition method of the gesture recognition sensor is not limited, and matching recognition of gesture actions can be achieved. The following explains the gesture image recognition process in Dynamic Time Warping (DTW): when a first gesture image acquired by a gesture recognition sensor is an image sequence in which a finger of a user slides in the air from top to bottom, an optimal state estimation based on a current observation track is searched by taking a finger motion track in the first gesture image sequence to be recognized as an observation amount, namely a matched preset gesture image is searched (note that the preset gesture image is also a group of image sequences), an optimal recognition result is obtained, namely the matched preset gesture image is obtained, and a first control instruction corresponding to the matched preset gesture image is an instruction represented by a gesture action of the user, for example, an instruction for darkening the color of a car window; similarly, when the first gesture image acquired by the gesture recognition sensor is an image sequence in which the finger of the user slides from bottom to top, it is finally determined that the first control instruction corresponding to the other group of preset gesture image sequences is an instruction represented by the gesture action of the user, for example, an instruction for making the color of the vehicle window transparent.
The gesture recognition sensor sends the acquired first control instruction to a device with a control execution function, such as a controller.
And 103, controlling the color change of the vehicle window by the controller according to the first control instruction.
The controller is mainly divided into a combinational logic controller and a micro-program controller. The combinational logic controller is composed of logic circuits and completely realizes the function of instructions by hardware; the micro-program controller is internally provided with a chip, micro-programs corresponding to the instructions of each machine can be written in the chip, and the functions of the instructions are realized by executing the micro-programs. The controller described in the present invention may be either one of the two.
The controller receives a first control instruction sent by the gesture recognition sensor, and then processes and executes the control instruction.
If the gesture recognition sensor is connected with the combinational logic controller, the instruction register of the combinational logic controller receives and stores the control instruction, and the combinational logic controller can perform circuit implementation on the received first control instruction of the gesture recognition sensor according to the time and what operation is performed on what component of each control instruction through a preset instruction processing flow, so that the color of the car window glass is darkened or becomes transparent.
If the gesture recognition sensor is connected with the micro-program controller, a decoder of the micro-program controller is an entry address of a control instruction, the decoder takes out each micro-instruction of the micro-program corresponding to the first control instruction one by one and stores the micro-instruction into the micro-instruction register, and an execution part of the controller reads out the micro-instructions one by one, so that various operation control signals are generated, the corresponding part executes the specified operation, and the color of the car window glass is darkened or becomes transparent.
It should be noted that the vehicle window described in the present invention is a color-changeable vehicle window, and the change of the vehicle window color refers to the vehicle window becoming dark or transparent.
At present, the realization technology of the color-changing car window is multiple. For example, a film embedded with special substances can be added into common car window glass, when the electricity is electrified, the substances automatically stand in parallel, the car window becomes bright, and when the electricity is off, the substances automatically and randomly combine, and the car window becomes dark; some techniques use glass capable of adjusting the light transmittance, and thus can also change the color of the window glass; in some technologies, a layer of adhesive film capable of changing color is added on the outer surface of common car window glass, and the car window is changed in color by changing the color of the adhesive film. The type or implementation technology of the color-changing vehicle window is not particularly limited, as long as the color-changing effect is satisfied.
In summary, in the car window color control method provided in the embodiment of the present invention, a gesture recognition sensor acquires a first gesture image of a user, the gesture recognition sensor acquires a first control instruction corresponding to the first gesture image according to a relationship between a preset gesture image and a control instruction, and a controller controls a change of a car window color according to the first control instruction corresponding to the first gesture image. Like this, when the passenger needs the door window to become dark in order to shelter from sunshine in the car, or when needing the door window to become transparent in cloudy day, only use the change of gesture action alright control door window colour, avoided finger direct contact window glass or physical switch and make finger dirty or glass dirty, operation laborsaving and clean health has promoted user's experience of riding.
Referring to fig. 2, a flowchart of the window color control according to the embodiment of the present invention is shown, that is, the window color control flowchart when the first control instruction is an electrical signal.
When the first control instruction output by the gesture recognition sensor is an electric signal, the controller controls the power on or off of the circuit of the car window according to the electric signal so as to control the color change of the car window.
Specifically, the electrical signal is divided into a high level signal and a low level signal, and those skilled in the art should understand that the logic levels corresponding to the voltages of the digital circuits formed by different components are different. In the TTL gate circuit, 3.4-4.0V voltage is defined as logic high level, and the voltage less than 0.0-0.3V voltage is defined as logic low level; for CMOS the high level is 4.99 volts-4.0 volts and the low level is 0.0 volts-0.01 volts. Therefore, the voltage range represented by the high and low levels is determined by a specific circuit, and the voltage ranges of the high and low levels are not particularly limited in the present invention.
And after the controller receives the high-level signal, the controller controls the circuit of the car window to be electrified, and the color of the car window is changed into transparent. Specifically, the controller intervenes a switch device connected with a window glass circuit according to a preset instruction processing flow to close a switch, for example, the switch device is a relay, and the relay is subjected to suction processing. When the switch device on the circuit is closed, the circuit connected with the window glass is electrified, so that the window glass is in a transparent state.
And after the controller receives the low-level signal, the controller controls the circuit of the car window to be powered off, and the car window becomes dark in color. Specifically, the controller intervenes a switching device on the vehicle window glass connection circuit according to a preset instruction processing flow to turn off the switch, for example, the switching device is a relay, and the relay is turned off. When the switch device on the circuit is turned off, the circuit of the window glass is cut off, so that the window glass becomes an opaque state, namely becomes dark.
Obviously, in addition to the technical scheme that the high level signal is correspondingly powered on and the low level signal is correspondingly powered off, the invention can also adopt the technical scheme that the low level signal is correspondingly powered on to ensure that the color of the car window becomes transparent, and the high level signal is correspondingly powered off to ensure that the color of the car window becomes dark, and only the preset instruction processing flow of the controller needs to be changed. Both of the above schemes can achieve the purpose of the invention.
According to the implementation process of the car window color control method provided by the embodiment of the invention, when a user makes a first gesture action, the gesture recognition sensor outputs an electric signal by acquiring and matching a gesture image, and the controller controls the power on or off of the circuit of the car window according to the electric signal so as to control the change of the car window color. By adopting the technical scheme, the automobile window color changing device has the advantages of simple principle, convenience in implementation and high execution speed, can directly control the circuit of the automobile window according to the voltage signal, quickly realize the color change of the automobile window, and further more efficiently meet the requirements of users.
Referring to fig. 3, a flowchart illustrating steps of a vehicle window color control method according to an embodiment of the present invention is shown.
Step 301, acquiring a second gesture image of the user by the gesture recognition sensor;
the second gesture image may correspond to any image different from the first gesture image, and the second gesture image is preset by the user as well as the first gesture image. For example, the gesture motion can be a double-click gesture motion of the finger of the user in the air, and the gesture image acquired by the gesture recognition sensor corresponds to a sequence image of the double-click process of the finger of the user in the air.
Step 302, acquiring a second control instruction corresponding to the second gesture image by the gesture recognition sensor according to a preset relationship between the gesture image and the control instruction;
and the gesture recognition sensor compares the current second gesture image acquired by the camera with a preset gesture image stored in the gesture recognition sensor in advance, and acquires a control instruction corresponding to the preset gesture image as a second control instruction corresponding to the second gesture image.
For example, the second control instruction corresponding to the second gesture image of double-click of the finger of the user in the air is: and enabling the controller connected with the gesture recognition sensor to enter a working mode, and sending the second control instruction to the controller by the gesture recognition sensor.
And step 303, controlling the controller to enter a working mode according to the second control instruction by the controller.
After the controller receives the control instruction, the control instruction is programmed into micro instructions, the controller execution module reads the micro instructions to generate operation control signals, the operation control signals are signals enabling the controller to enter a working mode, at the moment, a chip of the controller is awakened, and the controller enters the working mode.
After step 303, two situations are divided, that is, the situation where the user does not make any gesture any more and the situation where the user makes the first gesture, and the specific flow method will be different in different situations. Case one is step 304, and case two is steps 305, 306, 307, 308.
Step 304, in a preset time, when the controller does not receive the first control instruction, the controller enters a standby mode.
After the user makes the second gesture motion, the user does not make any gesture motion which can enable the gesture recognition sensor to generate the first control instruction within the preset time, such as the first gesture motion, and then the second gesture motion in the previous step is considered as the meaningless motion of the user by the controller, and the controller enters the standby mode. The preset time needs to be set in the controller in advance by the user, and may be 10 seconds or 20 seconds, for example.
Step 305, acquiring a first gesture image of a user by a gesture recognition sensor;
step 306, acquiring a first control instruction corresponding to the first gesture image by the gesture recognition sensor according to a relation between a preset gesture image and the control instruction;
and 307, controlling the color change of the vehicle window by the controller according to the first control instruction.
These three steps are the same as step 101, step 102 and step 103, and are not described again here.
Step 308, in a preset time, when the controller does not receive the first control instruction, the controller enters a standby mode.
And after the user makes a second gesture action and the controller enters a working mode, the user makes a first gesture action to change the color of the car window, and thus, a complete car window color control process is completed. After that, within the preset time, the user does not make the first gesture again, that is, the controller does not receive the first control instruction, the controller may think that the user no longer needs to change the color of the window, at this time, the controller automatically enters the standby mode, and the power consumption becomes lower. The setting of the step can avoid unnecessary power consumption loss of the controller and slow down the aging of the internal components.
According to the car window color control method, before the user controls the car window color operation, a step of enabling the controller to enter a working mode is added, and a step of enabling the controller to enter a standby mode is also added after the user performs a second gesture action and after the user controls the car window color. When a user takes a car, the user may unintentionally perform some actions similar to the gesture actions preset by the gesture recognition sensor, and as long as the gesture actions are collected and processed by the gesture recognition sensor within the recognition distance of the gesture recognition sensor, the controller executes the control command and controls the color change of the car window, which is not the intention of the user. Therefore, the step of enabling the controller to enter the working mode is added before the step of controlling the color of the vehicle window, so that the careless loss of a user can be effectively prevented: even if the user makes the first gesture action, the controller will not respond to the control command sent by the gesture recognition sensor and the vehicle window will not change color because the user does not make the second gesture action for enabling the controller to enter the working mode before the gesture action. And after the user makes a second gesture action and the user controls the color of the car window, a step of enabling the controller to enter a standby mode is added, namely the conversion between the working mode and the standby mode of the controller is added, so that the power consumption of the controller and the loss of internal components of the controller are greatly reduced. In summary, the method of the embodiment greatly reduces the misoperation risk of the user, brings better use experience to the user, and is more energy-saving and environment-friendly.
