Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a motion teaching apparatus provided in an embodiment of the present application, and for convenience of description, only a portion related to the embodiment of the present application is shown.
As shown in fig. 1, a motion teaching apparatus 100 includes: an image display unit 10, an image pickup unit 20, a moving body wearing unit 30, and an image output unit 40. Specifically, the method comprises the following steps:
an image display unit 10 for displaying a preset motion teaching image and a target posture image; wherein, the image content of the motion teaching image is used for the simulation of the moving body.
And the image acquisition unit 20 is used for acquiring real-time attitude images when the moving body imitates the image content of the motion teaching images.
And a moving body wearing unit 30 for wearing on a moving joint of the moving body and collecting spatial position information of the moving joint.
And the image output unit 40 is respectively connected with the image display unit 10, the image acquisition unit 20 and the moving body wearing unit 30, and is used for generating a target posture image according to the real-time posture image, the spatial position information and the motion teaching image.
In this embodiment, the image display unit 10, the image capturing unit 20, and the moving object wearing unit 30 are respectively connected to the image output unit 40, wherein the image display unit 10 and the image capturing unit 20 are both electrically connected to the image output unit 40 by a wired connection, and the moving object wearing unit 30 is connected to the image output unit 40 by a wired connection. In other embodiments, the moving body wearing unit 30 and the image output unit 40 may be connected wirelessly.
The image display unit 10 displays the motion teaching image first, and the image display unit 10 displays the target posture image only when the image output unit 40 generates the target posture image and the image display unit 10 receives the target posture image transmitted by the image output unit 40. The image acquisition unit 20 acquires a real-time posture image when the moving body simulates the image content of the motion teaching image and transmits the real-time posture image to the image output unit 40, and the moving body wearing unit 30 is worn on the moving joint of the moving body, so that when the moving body simulates the image content of the motion teaching image, the moving body wearing unit 30 can acquire the spatial position information of the moving joint and transmit the spatial position information to the image output unit 40. The image output unit 40 generates a target posture image from the real-time posture image, the spatial position information, and the motion teaching image.
It should be noted that the preset motion teaching image content displayed in the image display unit 10 is used for the moving object simulation, that is, the motion teaching image is an image containing the moving posture or motion of the moving object. In all embodiments of the present application, the moving object may include a human being, or a robot capable of simulating the motion content of the motion teaching image, which is not limited herein. When the image display unit 10 displays the motion teaching image, the moving object simulates the motion teaching image by observing the content of the motion teaching image, and the image acquisition unit 20 acquires the image of the motion simulated motion of the moving object, that is, the real-time posture image of the moving object acquired by the image acquisition unit 20 corresponds to the image content of the motion teaching image in time sequence, that is, the real-time posture image of the moving object is a motion image made by the image content of the motion simulated motion teaching image of the moving object, that is, the image content of the motion simulated motion teaching image of the moving object corresponds to the real-time posture image of the moving object in time sequence. The moving body wearing unit 30 is worn on the moving joint of the moving body, and the moving body wearing unit 30 can acquire spatial position information of the moving joint of the moving body when the moving body simulates the image content of the motion teaching image. The image output unit 40 can determine the moving joint area of the moving body in the real-time posture image according to the spatial position information.
In order to identify how similar the image content of the moving object imitating the motion teaching image is, the image output unit 40 is used to combine the spatial position information with the real-time posture image, that is, to determine the moving joint area of the moving object in the real-time posture image and distinguish the moving joint area from other areas. And then comparing the motion gesture with the motion teaching image, and further determining the difference between the motion gesture simulated by the moving body and the image content of the motion teaching image. In all embodiments of the present application, the spatial position information includes kinematic joint position information and joint spatial information, where the kinematic joint position information is used to distinguish the position of a kinematic joint in a moving body, for example, to distinguish a wrist, an elbow, a shoulder, and the like. The joint space information is used to distinguish the positions of the moving joints in the real-time posture image, for example, to distinguish the wrist position, elbow position, shoulder position, and the like in the real-time posture image. The moving joint of the moving body and the specific position of the moving joint in the real-time attitude image can be determined in the real-time attitude image based on the spatial position information. Based on the comparison between the position of the motion joint and the characteristic position in the motion teaching image, the similarity or difference degree of the motion content of the motion body imitating the motion teaching image can be determined, and then a target posture image is generated.
Taking the example that the moving body is a human body and the moving body wearing unit 30 is a bracelet, the moving body wearing unit 30 is worn on the wrists on the left and right sides of the human body, the image acquisition unit 20 acquires images simulating the motions of the human body, and the obtained real-time posture images of the human body are obtained, because the moving body wearing unit 30 is worn on the wrists on the left and right sides of the human body, the position of the moving body wearing unit 30 can represent the spatial position of the wrists of the human body, that is, the spatial position information of the wrists of the human body acquired by the moving body wearing unit 30 can be displayed in the real-time posture images, that is, the wrists on the left and right sides of the human body can be determined in the real-time posture images of the human body according to the spatial position information, that is, the pixel range. Therefore, without image processing or feature recognition on the real-time attitude image, the image output unit 40 can be used to determine the position of the motion joint, i.e. the pixel range, from the real-time attitude image, and compare the position of the motion joint with the reference position of the motion joint preset in the motion teaching image, so as to determine the similarity degree or difference degree of the motion content of the human body imitation motion teaching image, and further generate the target attitude image.
It is understood that all units in the motion teaching apparatus provided in the present application are hardware entity units, for example, the image display unit 10 may be a display screen, a projector, AR glasses or VR glasses, the image acquisition unit 20 may be a camera or a computer with a camera function, the moving body wearing unit 30 may be any existing wearing apparatus in any wearing form, and the image output unit 40 may be an existing image processing chip, an image processor or an image processing server.
In practical applications, the moving body wearing unit 30 collects spatial position information of a moving joint, which may be specifically implemented by configuring a sensor pair, for example, a signal receiver and a signal transmitter are respectively built in the moving body wearing unit 30 and the image output unit 40, and spatial position information of the moving joint may be collected by information interaction between the signal receiver and the signal transmitter, where the spatial position information represents a pixel point coordinate set of the moving joint in a real-time attitude image, so the image output unit 40 may determine a range of the moving joint from the real-time attitude image according to the pixel point coordinate set, and thus, a position of each moving joint, that is, a pixel point range, may be determined in the real-time attitude image without performing image processing or other operations on the real-time attitude image.
In this embodiment, the image output unit 40 compares the position of the motion joint with a reference position of the motion joint preset in the motion teaching image, specifically, the position pixel coordinates of the motion joint and the reference position pixel coordinates are compared, and the more the pixel coordinate deviation numbers of the motion joint and the reference position pixel coordinates are, the larger the numerical value of the attitude difference information is.

As a possible implementation manner of the present embodiment, the image output unit 40 is specifically configured to generate the target correction image when the posture difference information is equal to or greater than a preset threshold. And when the posture difference information is smaller than a preset threshold value, generating a target completion image.
