Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments of the present invention, belong to the protection scope of the present invention.
Referring to fig. 1 and fig. 2, the continuous fitting method of the fitting robot of the present invention uses a device including a deformable robot 1 and a camera assembly 2 for taking a picture of the whole body of the robot 1, wherein the robot 1 is wearing a garment to be measured. It should be noted that the robot 1 in the present invention includes not only a human-shaped robot model but also an animal-shaped robot model and an irregularly-shaped robot model, and it is important that the robot 1 has an automatic deformation function; the invention realizes the purpose of simulating human bodies with different body types by utilizing the automatic deformation function of the robot 1. Since the automatically deformable robot 1 is a conventional technology which is available and can be realized, the operation principle, the mechanical structure, the circuit design diagram and other details of the robot 1 are not changed or improved in the present invention, and thus, the details are not described in detail.
Wherein the fitting method comprises the following steps,
firstly, the robot 1 is erected and installed on a rotatable platform 3, so that the rotatable platform 3 drives the robot 1 to axially rotate at a constant speed along the horizontal direction. When the rotatable platform 3 is preset to rotate at a constant speed, the rotating speed is v.
Step two, the rotatable platform 3 rotates for a plurality of circles, the camera shooting assembly 2 shoots the robot 1 at the same frame rate and obtains a plurality of films with the same shooting time length, each film comprises the content of the robot 1 shot in the process that the rotatable platform 3 just finishes at least one integral circle, and the ending time of the previous film in the adjacent films is the starting time of the next film;
and step three, comparing any two films or any plurality of films.
When the technical scheme is adopted, the robot 1 is driven by the rotatable platform 3 to rotate at a constant speed all the time, and the number of frames of the camera shooting assembly 2 during camera shooting is kept unchanged all the time, so that the preset robot 1 is in a vertical posture, the camera shooting assembly 2 which is located at a fixed position and has a fixed camera shooting direction performs camera shooting to obtain two films in two turns of the adjacent robot 1, the facing direction of the robot 1 at any position on a time axis always faces to the same direction, namely the robot 1 in the two films repeats the same posture, facing direction and action in the process of two turns.
Let the rotation speed be v and the frame rate be p. The time required by the robot 1 to rotate for one circle at a constant speed can be converted through the rotating speed v, and the shooting time of the shooting assembly for shooting the robot 1 to rotate for one circle is also the time, so that the length of the time axis is obtained; in combination with the frame rate p, the number of single-frame images of the movie shot by the camera assembly 2 when the robot 1 rotates one turn can be converted, and the length of the time axis of the movie shot by the camera assembly 2 and the number of single-frame images in the movie are the same in each turn of the rotation of the robot 1.
By utilizing the two points, (1) the robot 1 in two adjacent circles of films repeats the same gesture, orientation and action in the process of two circles of rotations, and (2) the time axis length of the film obtained by shooting by the camera assembly 2 in each circle and the number of single-frame images in the film are the same, and by combining the deformation capability of the robot 1, if the robot 1 is preset to have different deformations in one circle of each rotation of the robot 1, the robot 1 with different deformations in the two adjacent circles can be put out of the same gesture to carry out comparison of the circle shooting state when wearing the same type of clothes, so that the comparison condition that different human bodies wear the same type of clothes in the same time can be effectively simulated.
Moreover, the film is substantially a process in which a plurality of single-frame images are continuously displayed at a preset switching frequency according to the sequence of the time axis, so that the film can be cut into a plurality of segments according to the time axis, so as to compare segments with the same time axis segment in two films respectively recording two revolutions of the robot 1, and also can perform frame-by-frame extraction on the film and obtain a plurality of single-frame images, so as to compare two single-frame images located at the same time point in any two films or any plurality of films, wherein the robots in the two single-frame images are wearing the same clothes and have the same posture and orientation.
Simultaneously, as long as the number of turns that robot 1 rotated is enough, and can guarantee that robot 1 rotates a plurality of integer numbers back every time, can both switch into different deformations, just can simulate out the condition that different human body types put out the same gesture and contrast at same time length of time with dress of style in succession, and then realize robot 1's continuous fitting. Therefore, in the second step of the first embodiment of the present invention, after the robot 1 rotates at least one integer circle, the robot 1 may be selectively deformed, when the robot 1 completes one circle and is photographed by the photographing component 2 for one circle, the photographing component 2 stops photographing, and the robot 1 deforms, and until the robot 1 finishes deforming, the photographing component 2 again photographs; of course, the camera assembly 2 may also perform continuous and uninterrupted camera shooting, and then the obtained whole camera shooting is clipped out of the process of deformation of the robot 1 each time, so as to obtain a plurality of films which are respectively displayed by the robot 1 rotating a plurality of integral circles each time.
Moreover, the rotation speed v and the frame rate p can be manually controlled and adjusted, so as to control the duration of the movie taken by the camera assembly 2, the number of single-frame images included in the movie, and the orientation of the posture exhibited by the robot 1 at each time node on the movie time axis when the robot 1 makes one rotation.
Further, the deformation number of each time of the robot 1 is preset as Y n And the films shot by the camera assembly 2 in each circle are numbered as X according to the sequence of the integral number of the circles of the camera m The set of all movies of all pose orientations of all deformations of the robot 1 is therefore Y n X m . For example Y 1 X 3 Is the third film, Y, of the first deformation of the robot 1 2 X 3 Is the third film of the second deformation of the robot 1, so contrast Y 1 X 3 And Y 2 X 3 Can be aligned to two kinds of deformation Y 1 And Y 2 The comparison is carried out under the condition that the same type of clothes are put in the same posture, and the comparison not only comprises the comparison of the display conditions of the two robots 1 in the whole film, but also comprises the comparison of the display fragments of the two robots 1 with the same time axis paragraph in the two films, and also comprises the comparison of the fitting conditions of the robots 1 in the two single-frame images obtained by frame extraction at the same time axis node in the two films.
However, the skilled person finds that in the practical operation process, two problems exist in the first embodiment:
firstly, in order to make the camera assembly 2 take two images to take the same posture of the robot 1, it is necessary to ensure that the starting orientation and the ending orientation of the robot 1 during two turns are the same; however, the robot 1 may deform slowly or rapidly, and it is difficult to avoid the above problem if it is preset that the robot 1 starts imaging after deformation is completed.
Therefore, in a second embodiment of the present invention, a method of counting turns is used to solve this problem.
Specifically, the camera module 2 starts imaging the robot 1 until the rotatable platform 3 has completed one rotation, and starts counting by the rotation.
First, in a single turn, the camera assembly 2 takes a picture of the robot 1 and obtains a movie.
After completing the single-turn photographing, the photographing module 2 may stop photographing generally in order to save the photographing cost; after the robot enters the even number of turns, the robot 1 can deform under the condition of keeping constant-speed rotation, and the deformation is finished before the even number of turns are finished; and then the next single-circle camera assembly 2 is used for shooting again. This ensures that the starting and ending orientations of two consecutive single turns of the robot 1 are the same. Because the robot 1 may not complete the deformation for a couple of turns at a time due to different deformation speeds, the robot 1 may be set to rotate for one turn to take a picture, then rotate for two or more turns to deform, the number of turns of taking a picture and deforming each time is combined into one process, and the processes are repeated.
Secondly, the rotatable platform 3 has a section of acceleration process when it reaches a constant speed during the actual working process, and has a section of deceleration process when it stops, and the rotation speed change will have a bad influence on the image pickup of the image pickup assembly 2.
Therefore, in the third embodiment of the present invention, the rotatable platform 3 starts to rotate to and keep rotating at a constant speed from the standing state, and then the camera assembly 2 starts to take a picture of the robot 1; meanwhile, the robot 1 always rotates at a constant speed in the deformation process, and the problem that the camera shooting process is prolonged because the robot stops rotating to deform and then rotates again is avoided.
The fourth embodiment of the present invention is realized by the following means.
As shown in fig. 1 and fig. 4, the camera assembly 2 includes at least two camera groups 201, each camera group 201 is disposed at intervals around the robot 1, the camera directions of the camera groups 201 are arranged to intersect, and the plurality of camera groups 201 can take images of the robot 1 from different directions, for example, upward and downward, so that the robot 1 can take images and record the clothes posture from a plurality of angles.
When the robot 1 is fitting, the surrounding environment is usually set as a background. When a plurality of shooting groups 201 are used for shooting, if one shooting group 201 shoots another shooting group 201 into the movie, the movie needs to be subjected to PS subsequently, which increases the work of personnel.
In order to avoid this problem, it is necessary to arrange the image capturing directions of the plurality of image capturing groups 201 in a crossed manner, and the projection of the image capturing directions of any two image capturing groups 201 on a horizontal plane forms an included angle α, which is not greater than 180 degrees, and preferably 120 degrees. Meanwhile, an extension line of the projection of the shooting direction of one shooting group 201 on the horizontal plane is taken as a base line, and the projections of the rest shooting groups 201 on the horizontal plane are all positioned on the same side of the base line, so that the robot 1 has a 180-degree non-shielding environment background.
The fifth embodiment of the present invention is realized by the following means.
As shown in fig. 1 and fig. 3, the front surface of the robot 1 is divided into a plurality of zones in the vertical line direction, so that the robot 1 can be divided into a plurality of zones such as a head, a neck, a chest, a waist, an abdomen, thighs, and calves from top to bottom.
The camera assembly 2 is thus arranged to comprise a plurality of camera units 21, the plurality of camera units 21 being arranged uniformly along the vertical line, each camera unit 21 taking images of at least one of the subareas, so that different robot 1 surface subareas can be taken images to obtain a film of the surface details of the robot 1.
As an alternative embodiment, the number of camera units 21 is not more than the number of divisions of the surface of the robot 1, so that each camera unit 21 can simultaneously image a plurality of divisions.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
