Example 1
As shown in fig. 1, the application scene is an application scene graph according to an embodiment of the present disclosure, where the application scene is an applet providing real-time interaction using real expressions, and the applet includes a first area and a second area, the first area is used for displaying a real avatar of a user and a character tag displayed in cooperation with the real avatar, the real avatar is acquired by a camera of a mobile terminal and then projected to a display interface, and the second area is an area providing data interaction with the first area. For example, one embodiment is where the second area includes a plurality of confrontational minuses, the minuses competing with users of the first area; another embodiment is that the second area is a real head portrait of another user, the two users carry out fighting, the two areas carry out fighting by launching various weapons, and the launching of the weapons is controlled by the expression motions of the characters. However, the present invention is not limited to the above application scenario, and any interaction scenario that can be applied to the present embodiment is included, and for convenience of description, the present embodiment takes the application scenario of the above character confrontation applet as an example.
As shown in fig. 2, according to a specific embodiment of the present disclosure, the present disclosure provides an interaction method based on multiple emotions, which includes the following steps:
step S202: the method comprises the steps of obtaining an expression image of a user through a camera, and displaying the expression image on an interactive interface.
The camera can be a device which is carried by any terminal and is used for conveniently acquiring the head portrait of the user, and is particularly suitable for mobile terminals, mobile phones and other devices. The camera stores the acquired expression images of the user in a terminal memory, and then the expression images are displayed on an application program interface after being called by the application program.
The mobile terminal client side obtains the expression image information and then sends the expression image information to the display interface, and in one implementation mode, real facial information of a user can be displayed on the display interface and can move in real time along with the action of facial expressions of the user, and the display mode can increase the interest of the user in interaction. In another embodiment, after the real facial expression of the user is obtained, the user can select whether to display the real facial expression or not through the interface, if not, a model facial display can be selected, any position of the model facial expression corresponds to the position corresponding to the user facial expression one by one, and when the facial expression changes, the expression at the corresponding position of the model also reflects the corresponding change. For example, selecting any preset head portrait of dinosaur model, cartoon model and the like.
As shown in fig. 1, the application program is usually an applet that can be opened at any time, the applet has the advantage of flexible and convenient access, and can be used for entertainment of a user at any time and any place, one embodiment is that the applet interface is divided into an upper area and a lower area, and characters between the two areas interact, for example, the applet includes a first area and a second area, the first area is used for displaying a real avatar of the user and a character tag displayed in cooperation with the real avatar, such as a life value of a character, a money amount of the user, a score value, a weapon amount, and the like, the real avatar is acquired by a camera of the mobile terminal and then is thrown into the display interface, and the second area is an area for providing data interaction with the first area. The first region receives the real-time head portrait of the user, and performs multi-dimensional interaction with the second region through cooperation of real-time facial expression and head expression actions of the user, and the interaction mode is not limited, for example, a mouth launches a fireball to the second region, and an ear launches a weapon such as a bullet to the second region. The second interface comprises a battle type character role which can adopt evasion and defense means to fight weapons such as fire balls and bullets launched from the first area. While the interactive objects (e.g., characters) of the second zone may launch weapons or other indicia such as fireballs, bullets, etc. The user is also protected from an aggressive interaction by the second zone. After the two interactive parties are attacked, the information (such as the life value) representing the end of the interaction is reduced until one interactive party is reduced to zero, and the interaction is ended.
Optionally, the obtaining of the expression image of the user through the camera and displaying the expression image on the interactive interface include:
the method comprises the steps that a real expression image of a user is obtained through a camera, and the real expression image is displayed on an interactive interface in real time; or,
the method comprises the steps of obtaining a real expression image of a user through a camera, selecting a model head portrait matched with the real expression image, and displaying the model head portrait on an interactive interface in real time.
The method comprises the steps of displaying with a real head portrait or with a model head portrait, selecting in the process of entering an interactive interface, and further selecting which model head portrait to display when selecting to display with the model head portrait, for example, selecting a dinosaur or frog animal head portrait model, selecting an animation head portrait model, and the like.
Step S204: monitoring the motion characteristics of the expression images in real time, wherein the motion characteristics comprise: head motion characteristics, eye motion characteristics, and mouth motion characteristics.
As shown in fig. 3, after the expression image of the real avatar or the model avatar of the user is acquired, the change process of the expression image needs to be monitored in real time in a software and/or hardware manner, and whether there is any motion in the head, eyes and mouth region is monitored.
Wherein the monitoring of the head region is by monitoring whether the position of the ears and/or nose changes; monitoring the eye region by monitoring whether the positions of eyebrows, eyelids and pupils are changed; the mouth region is monitored by monitoring whether the position of the upper lip, lower lip, and chin changes.
Optionally, the motion characteristics of the expression image are monitored in real time, and the motion characteristics include: head motion characteristics, eye motion characteristics, and mouth motion characteristics, comprising the sub-steps of:
step S204-1: the expression image is divided into a head region, an eye region, and a mouth region, as shown in fig. 3.
Optionally, the head region, the eye region and the mouth region include a plurality of feature regions, including: the characteristic region of the head region includes: ears and nose; the characteristic region of the mouth region includes: upper lip, lower lip and chin; the characteristic region of the eye region includes: eyebrows, eyelids, and pupils.
Step S204-2: at least one feature point is selected in each of the feature regions.
Feature points, which are randomly defined for analyzing the movement of each region of the face, may be selected from one or more feature points, as shown in fig. 3, for example, the feature points selected in the head region may be the feature point a1 selected on any one or two ears, and the feature point a2 selected on the tip of the nose; the feature points selected in the mouth region may be feature point b1 selected on the upper lip, feature b2 selected on the lower lip, and feature point b3 selected on the chin; the feature points selected in the eye region may be feature point c1 selected on any eyebrow, feature c2 selected on any eyelid, and feature point c3 selected on any pupil. The feature points are selected arbitrarily, but the positions with obvious action amplitude of the feature areas, such as the center of lips and the bottommost position of chin, are preferably selected, so that the motion vectors of the feature points can be accurately recorded.
Step S204-3: and monitoring the motion characteristics of the expression image through the position change of the at least one feature point.
As an optional implementation, the monitoring the motion characteristic of the expression image through the position change of the at least one feature point includes:
determining location information of the at least one feature point. Determining a movement vector R of the at least one feature point by the change of the position information. And monitoring the motion characteristics of the expression image through the movement vector R of the at least one feature point.
Determining a movement vector R of at least one feature point by a change in position information of the at least one feature point, e.g. at a first time t1And acquiring first position coordinate information of one characteristic point. At a second time t2And obtaining second position coordinate information of the same characteristic point. And calculating the movement vector R of the characteristic point according to the first position coordinate information and the second position coordinate information. Wherein the second time t2And a first time t1Is within a preset range. The interval Δ t passes within 0.1-2s, and if the interval time is too long, it can be considered as ineffective autonomous control.
After the mobile terminal acquires the face information of the user through the camera, it monitors in real time whether the coordinate information of the feature point defined by the user changes, for example, first, after the interaction starts, the position coordinate parameter of the feature point a1 is recorded, and continuously monitors whether the position coordinate of the feature point a1 changes.
At t2At this time, if the mobile terminal monitors that the position information of the feature point a1 changes, for example, by comparing the coordinate parameters of the feature point a1, it can be determined whether the position of the feature point a1 changes. The position change is usually within a reasonable stroke, and if the position change exceeds the stroke, the position change can be judged to be abnormal, such as the camera moving amplitude is too large, or the user head portrait moves to other positions to cause uncontrolled action.
By calculating the coordinate parameter between the two positions, a movement vector R including a movement distance and a movement direction can be obtained, and by judging the movement direction, for example, the specific motion of each part of the facial expression can be determined.
As another optional implementation, the monitoring the motion characteristics of the expression image through the position change of the at least one feature point includes:
acquiring two continuous frames of images of the expression image; comparing the position information of all the characteristic points in the two continuous frames of images; monitoring whether the position information of each feature point is changed; and determining the action characteristics of the head region, the eye region and/or the mouth region according to the change of the position information of each feature point.
After the mobile terminal acquires the mouth region image of the user, the image after the small program is started is stored in a back-end database in real time, and at the moment, the database can continuously store the mouth image of the user. And for the stored mouth image, the back-end server compares the feature point position information in the two continuous frames of images in real time, if the two frames of images are the same, the same image in the previous frame is deleted, and if the feature point position information changes, the action characteristic of the mouth is determined according to the change. For example, it can be determined that the subsequent frame image is open, beep, or left-falling relative to the previous frame image.
Step S206: and when at least two action characteristics occur simultaneously, triggering the aggressive identification to display the aggressive identification on the interactive interface in a preset form.
When at least two of the above-mentioned action characteristics occur simultaneously, for example, the head moves (head shaking or nodding), the eyes move, such as blinking and eyebrow picking, or the mouth moves, such as a constant mouth-beeping, so that the three actions are combined to achieve the effect of shooting weapons by the eyes and/or mouth and directing the direction of the head.
The offensive mark can be presented in any form, such as a line, a circle, and the like, as a preferred mode, the offensive mark can be an offensive weapon matched with the actions of the head, the eyes, and the mouth, and different types of offensive marks can be presented on the interactive interface in a defining, setting, and rendering mode according to the requirements of different programs. For the type of countermeasure interaction, alternative offensiveness identifiers include, but are not limited to, laser beams, bullets, shells, fireballs, etc., each model having its own characteristics, such as injury characteristic values represented as data, velocity characteristic values represented as data, distance characteristic values represented as data, etc. For example, the injury characteristic value of a fireball is 10000, the velocity characteristic value is 100, and the distance characteristic value is 20; the attack injury characteristic value of the cannonball is 8000, the speed characteristic value is 200 and the distance characteristic value is 30; the bullet has an injury characteristic of 1000, a velocity characteristic of 300, a distance characteristic of 40, and so on.
Different types of offensive marks need to be rendered, so that the countermeasure effect is better, different weapons can be rendered with different effects in a rendering mode according to the appearance characteristic of authenticity, and the rendering method is a known method and is not described herein any more. Specific effects may be described as, for example, opening the mouth, releasing a fireball from the mouth, beeping the mouth to release a shell, skimming the mouth to release a bullet, etc. The above description of an attacking weapon is not to be taken as being exclusive.
Triggering different offensive marks according to different expression and action characteristics, wherein the offensive marks comprise an injury characteristic value, a speed characteristic value and a distance characteristic value, the injury characteristic value refers to a value which is matched with the injury characteristic value and is reduced by the life value of the interactive character after being attacked by a weapon with the injury characteristic value, for example, the value is 100000, and the value is reduced by 10000 after being attacked by a fireball; the speed characteristic value refers to a moving speed of the weapon on a screen after the weapon is fired, for example, the moving speed of a fireball is 100, and the corresponding moving speed can be a moving speed marked by 100 pixels or other corresponding marking modes; the distance characteristic is the distance at which the weapon can fire, for example a fireball can only fire at a position directly under the mouth, while a bullet can fire the entire screen. The features of the attacking weapon may also include the range of damage to the weapon, for example the fireball may have a diameter, and the range of damage may be a range slightly larger than the fireball diameter, so long as targets within this range are damaged.
For example:
opening mouth to trigger a first aggressive identification, wherein the first aggressive identification has a first injury characteristic value, a first speed characteristic value and a first distance characteristic value; and/or the presence of a gas in the gas,
the beep mouth triggers a second offensive flag having a second injury characteristic value, a second speed characteristic value, and a second distance characteristic value; and/or the presence of a gas in the gas,
the mouth-left trigger triggers a third offensive identifier having a third injury characteristic value, a third speed characteristic value, and a third distance characteristic value.
The first injury characteristic value is greater than a second injury characteristic value, which is greater than a third injury characteristic value; the first speed characteristic value is less than a second speed characteristic value, which is less than a third speed characteristic value; the first distance eigenvalue is less than a second distance eigenvalue, and the second distance eigenvalue is less than a third distance eigenvalue.
