For customizing the problem that the earphone manufacturing cycle is long, manufacture efficiency is low, ear's model accuracy is difficult to guarantee in prior art, first embodiment of the invention provides a kind of manufacture method customizing earphone, as shown in Figure 1, comprises step 110 to step 140.
Step 110, obtains ear's view data of client upload and carries out pre-service, obtaining ear's picture.
Step 120, control model unit carries out three-dimensional modeling according to default setting to ear's picture, obtains ear's three-dimensional model.
Step 130, judges whether the degree of accuracy parameter of ear's three-dimensional model meets pre-conditioned, if meet, then prints ear's three-dimensional model; If do not meet, then correct ear's three-dimensional model according to preset rules, and print the ear's three-dimensional model after correcting.
Step 140, the ear's three-dimensional model according to printing manufactures earphone.
Visible, in the embodiment of the present invention, directly according to default setting, ear's three-dimensional model is set up automatically to ear's picture by control model unit, delivery repeatedly can be solved in prior art and just can obtain the problem of ear's model, and automatic modeling process can be realized.By arranging the degree of accuracy parameter of ear's three-dimensional model, and correct ear's three-dimensional model, can obtain enough accurate ear model, ear's model accuracy that in solution prior art, delivery causes repeatedly is difficult to the problem ensured.User ear model can be obtained fast by 3D printing technique, the making of earphone can be completed fast, solve prior art middle ear machine Production Time long inefficient problem.Therefore the method in the embodiment of the present invention efficiently can complete the manufacture of customization earphone fast, and ensures the degree of accuracy of ear's model.
In step 110, client stores ear's view data of customized user, and ear's view data comprises ear's image and acquisition parameters thereof.Pre-service is carried out, mainly to the pre-service of ear's image for the ear's view data uploaded.
Ear's image can be ear's photo, can also be the video of ear.
If ear's image is the multiple pictures of user ear, then during pre-service, need extract from multiple pictures can around user Dan Zhi ear at least 180 degree, and the every photo of picture registration more than 60% of adjacent two, ensure with this truth comprehensively restoring user ear, make ear's three-dimensional model of foundation enough accurate.
If ear's image is the video of user ear, then need to intercept into graphic form according to certain requirement, recommend intercept 2 or 3 p.s., make the picture registration of often adjacent two pictures reach more than 60%, thus ensure that the ear's three-dimensional model set up can restore the truth of user ear accurately comprehensively.
After obtaining multiple ear's photos, also need the adjustment these pictures being carried out to brightness, contrast during pre-service, make picture clear, be convenient to modeling.
By step 110, ear's image and acquisition parameters can be obtained according to ear's view data of client upload, and pre-service can be carried out to ear's image, obtain multiple the ear's pictures meeting modeling demand.
In the step 120, default setting at least comprises the load path of ear's view data, i.e. the load path of ear's image and acquisition parameters, and default feature point is arranged, and default mesh is arranged and acquiescence texture is arranged.The loading of view data, model characteristic point are extracted, the foundation of model meshes and model texture are arranged, and are the steps necessarys in modeling process, are set to the robotization that default setting can realize three-dimensional modeling.
Acquisition parameters is the parameter such as aperture, focal length when often opening photo or video capture.Automatically ear's image and acquisition parameters is loaded by control model unit, carry out acquiescence to acquisition parameters to calculate, take machine and clapped the information such as the relative position of picture when can learn image taking, thus real scene when restoring shooting accurately when modeling, ensure the degree of accuracy of ear's three-dimensional model.
It can be the parameter such as precision and mode of default setting unique point that default feature point is arranged.Suitable unique point is set by control model unit, the degree of accuracy of Modling model can be ensured, make ear's form of model rediscover to the full extent.
It can be mode and the parameter of default setting generating mesh that default mesh is arranged, and the feature of model can be made farthest to be reduced, make the image of model more concrete by rational mess generation.
It can be the superficial makings of default setting model that acquiescence texture is arranged, and is arranged the effect of ear's three-dimensional model can be made truer by suitable model texture.
Default setting also at least comprises that acquiescence modeling region is arranged, default size extracting parameter is arranged, default image position arrange in one or more, arranged by acquiescence modeling region, default size extracting parameter arranged, default image position arrange in one or more can ensure the degree of accuracy of three-dimensional model further.
It can be that default setting is for setting up the spatial dimension of three-dimensional model that acquiescence modeling region is arranged.By rational modeling region, can ensure to reject part unnecessary in picture, only modeling be carried out to the ear in picture.
It can be the size of default setting ear object of reference that default size extracting parameter is arranged.Extracted by size, ear's size can be gone out according to the Size calculation of periphery object of reference, thus make the size of ear's three-dimensional model consistent with full-size(d).
Default setting can also comprise default image position and arrange.Around an object shooting plurality of pictures according to the principle that three-dimensional model set up by picture, then position when plurality of pictures being arranged at shooting, plurality of pictures is all mapped to center, thus obtains the three-dimensional model of subject.It can thus be appreciated that picture position can ensure the consistance of three-dimensional model and the truth finally obtained accurately.
By loading acquisition parameters, acquiescence is carried out to acquisition parameters and calculates, also indirectly can obtain picture position, but the picture position obtained might not be accurate, by directly arranging picture position, can ensure the accuracy of picture position.
By step 102, directly can automatically set up ear's three-dimensional model to ear's picture according to default setting, in solution prior art, delivery just can obtain the problem of ear's model repeatedly.
In step 103, the ear's three-dimensional model built up has degree of accuracy parameter, and degree of accuracy parameter can represent the levels of precision of ear's three-dimensional model relative to true ear form.By judging whether degree of accuracy parameter meets pre-conditioned ear's three-dimensional model that can judge to set up and whether enough conform to actual ear form.
Particularly, judge whether the degree of accuracy parameter of ear's three-dimensional model meets pre-conditioned, at least comprise following in one or more: judge whether the unique point quantity of ear's three-dimensional model is greater than default unique point amount threshold; Judge whether the margin of error of ear's three-dimensional model is less than default margin of error threshold value; Judge whether the registration of ear's three-dimensional model is greater than default registration threshold value.
Unique point quantity is more, illustrate the feature extraction of ear's picture more abundant, thus more can obtain the model of closing to reality ear form, therefore unique point amount threshold is preset in step 130, when the unique point quantity of the ear's three-dimensional model set up is greater than default unique point amount threshold, represent that the degree of accuracy of ear's three-dimensional model is enough high.But the increase of unique point quantity, can cause modeling algorithm complicated, in order to avoid algorithm is too complicated, can also preset unique point transformation threshold value, judge whether the unique point quantity of ear's three-dimensional model is less than default unique point transformation threshold value.Unique point also can think the unique point on ear's picture.
The margin of error of ear's three-dimensional model is the margin of error calculated according to the unique point of ear's three-dimensional model, the situation that the feature that expression Mei Zhang ear picture extracts is not identical.The margin of error of ear's three-dimensional model is less, illustrates that the feature that Mei Zhang ear picture extracts is more consistent, illustrates that the ear's plesiomorphism degree in the ear's three-dimensional model and picture set up is higher.Default margin of error threshold value is set in step 130, if the margin of error of the ear's three-dimensional model established is less than default margin of error threshold value, illustrates that ear's three-dimensional model is more accurate.
The registration of ear's three-dimensional model is the registration of the three-dimensional model that when setting up ear's three-dimensional model, any two pictures map out.Modeling Shi Meizhang ear picture can map out ear's three-dimensional model, when the registration of any two the ear's models mapped out is all enough high, illustrates that the ear's form in all pictures enough expressed by the ear's three-dimensional model set up.Being provided with default registration threshold value in step 130, by judging whether the registration of ear's three-dimensional model is greater than default registration threshold value, can knowing that whether the form of ear's three-dimensional model is accurate.If the registration of ear's three-dimensional model is greater than default registration threshold value, illustrate that ear's three-dimensional model is enough accurate.
In step 130, if the degree of accuracy parameter of ear's three-dimensional model meets pre-conditioned, then can think that the ear's three-dimensional model set up is enough accurate, can 3D printing be carried out.If degree of accuracy parameter does not meet pre-conditioned, then need to correct ear's three-dimensional model according to preset rules, ear's three-dimensional model is met pre-conditioned, then carry out 3D printing.
Correct ear's three-dimensional model according to preset rules, can comprise: according to the departure of the degree of accuracy parameter of ear's three-dimensional model, change default setting also re-starts modeling, until the degree of accuracy parameter of the ear's three-dimensional model set up meets pre-conditioned.
Such as, if the unique point quantity of ear's three-dimensional model is less than default unique point amount threshold, then change the default setting in step 120, mainly change default feature point and arrange, enable modeling unit extract more unique point, thus obtain more accurate ear three-dimensional model.
If the margin of error of ear's three-dimensional model is greater than default margin of error threshold value, illustrate that the inconsistent situation of the unique point of every pictures is serious, then the default feature point changed in step 120 is arranged, and the feature that every pictures is extracted is more consistent.
If the registration of ear's three-dimensional model is less than default registration threshold value, illustrate that the model registration that any two pictures map out is not high enough, may be that the position that image is arranged is wrong, the acquiescence then changing the acquisition parameters in step 120 calculates or the setting of default image position, and the model that any two pictures are mapped is more consistent.
By step 130, judge whether degree of accuracy parameter meets pre-conditioned, thus undercorrection accurate ear three-dimensional model, can obtain enough accurate user ear model, ear's model accuracy that in solution prior art, delivery causes repeatedly is difficult to the problem ensured.Adopt 3D printing technique to print enough accurate ear three-dimensional model, user ear model can be obtained fast, solve the problem of ear's modelling time growth process complexity in prior art.
In step 140, manufacture ear casing according to accurate user ear three-dimensional model, thus complete the manufacture of customization earphone.
Visible, in the embodiment of the present invention, directly according to default setting, ear's three-dimensional model is set up automatically to ear's picture by control model unit, delivery repeatedly can be solved in prior art and just can obtain the problem of ear's model, and automatic modeling process can be realized.By arranging the degree of accuracy parameter of ear's three-dimensional model, and correct ear's three-dimensional model, can obtain enough accurate ear model, ear's model accuracy that in solution prior art, delivery causes repeatedly is difficult to the problem ensured.User ear model can be obtained fast by 3D printing technique, the making of earphone can be completed fast, solve prior art middle ear machine Production Time long inefficient problem.Therefore the method in the embodiment of the present invention efficiently can complete the manufacture of customization earphone fast, and ensures the degree of accuracy of ear's model.
