Since the content of the transparency item and the chroma item is similar to the clarity item, it will not be described in detail one by one here.

Referring to FIGS. 1 to 3 at the same time, the following exemplarily explains in detail how the gemstone appraisal device 1 of this embodiment implements a gemstone appraisal method.

First, in step S1, the processing unit 15 obtains a still image. In this embodiment, the way the processing unit 15 obtains the still image may be, for example, when a photographing instruction input by the user is received through the input unit 11, the photographing instruction is controlled by the photographing unit 13 according to the photographing instruction, Obtain the still image. However, the static image may also be stored in the storage unit 14 in advance, and the processing unit 15 may read the storage unit 14 according to the user's operation to obtain the static image, but not limited thereto. Next, step S2 is performed.

In step S2, when obtaining the still image, the processing unit 15 performs image recognition on the still image according to the certificate file template to determine whether there is a match with the certificate file template in the still image to present the certificate file Target area A1 (shown exemplarily in FIG. 3). When the result of the determination by the processing unit 15 is NO, step S3 follows. When the result of the determination by the processing unit 15 is YES, step S4 follows.

Specifically, in this embodiment, the processing unit 15 first determines whether the trademark design, the certificate title, and the identification items exist in the static image according to the certificate file template. Whether the relative positional relationship between the trademark design, the certificate title and the identification items in the image conforms to the format indicated by the certificate file template, and thereby determine whether the target area A1 exists in the static image, but Not limited to this. In addition, in this embodiment, the processing unit 15 may, for example, apply optical character recognition (Optical Character Recognition, OCR for short) technology in conjunction with various algorithms related to feature detection (Feature detection in English) to perform image recognition. For example, algorithms such as scale-invariant feature transform (SIFT in English), edge detection (Edge detection in English), corner detection (Corner detection in English), or ridge detection (Ridge detection in English) and other algorithms, but Not limited to this. It is added that in other embodiments, the processing unit 15 may also determine whether the target area A1 exists in the static image based on only one or a part of the trademark design, the certificate title and the identification items , Not limited to this embodiment.

In step S3, when the processing unit 15 determines that the target area A1 does not exist in the still image, it generates a warning notice and controls the output unit 12 to output the warning notice. In this embodiment, the way the output unit 12 outputs the warning notification is, for example, displaying a warning message, and the warning message may be, for example, "Unable to recognize your certificate picture, please take a new picture or upload", but not as limit.

In step S4 following step S2, when the processing unit 15 determines that the target area A1 exists in the still image, it performs image recognition on the target area A1 according to the certificate file template to generate a corresponding target area A1 Image recognition results. In this embodiment, the image recognition result includes a weight value, and four pieces of text data corresponding to the four valuation items, specifically, the weight value is the weight of a gemstone recorded in the certificate file, and the The four-stroke text data are a pair of variety text data corresponding to the gem variety item, a pair of origin text data corresponding to the gem origin item, a pair of cutting form text data corresponding to the gem cutting form item, and a pair of color gemstone color item Text data, but not limited to this.

The following details how the processing unit 15 obtains the weight value and the text data by performing image recognition.

The processing unit 15 obtains the weight value by performing image recognition to determine whether there is a numerical string V1 in the target area A1 that meets a predetermined condition (exemplarily shown in FIG. 3 ). In this embodiment, the predetermined condition includes the following two sub-conditions: 1. The numeric string V1 and a first string St1 that exists in the target area A1 and indicates a weight item match a first Relative positional relationship. In this embodiment, the first character string St1 is, for example, "Weight" shown in FIG. 3, and the first relative positional relationship represents, for example, that the numeric character string V1 is located below the first character string St1 and is A fixed line height apart, but not limited to this. 2. There is a second relative positional relationship between the numeric character string V1 and a second character string St2 that exists in the target area A1 and indicates a specific weight unit. In this embodiment, the second character string St2 is, for example, "ct" shown in FIG. 3 and indicates the weight unit of "carat", and the second relative positional relationship represents, for example, that the numeric character string V1 is located in the first The left side of the two-character string St2, and the distance between them by a half-shaped character, but not limited to this.

When the processing unit 15 recognizes that the value string V1 that meets the predetermined condition exists in the target area A1, the value indicated by the value string V1 ("5.74" shown in FIG. 3) is used as the Weight value. When the processing unit 15 recognizes that there is no numeric string V1 that meets the predetermined condition in the target area A1, it generates a weight input request and controls the output unit 12 to output the weight input request. In this embodiment, the output unit 12 outputs the weight input request by, for example, displaying a window with an input field, and the window indicates, for example, the message "Carat number cannot be recognized, please enter the carat number manually" , But not limited to this. Then, when the processing unit 15 receives an input value input by the user in the input field corresponding to the weight input request via the input unit 11, the input value is used as the weight value. By judging the predetermined condition, the processing unit 15 can correctly obtain the weight value from the target area A1 without mistakenly using other Arabic numerals in the target area A1 as the weight value.

The processing unit 15 obtains the text data by first recognizing the title positions of the project names in the target area A1, and then, the processing unit 15 corresponds to the target area A1 respectively. The plurality of sub-regions p1 to p4 at the same title position are used for image recognition to convert the images in the sub-region p1 to the sub-region p4 into the text data. In this embodiment, the sub-region p1 to the sub-region p4 are, for example, set to be respectively located below the positions of the titles, but it is not limited thereto.

Taking the variety text data in the four-stroke text data as an example, since the item name of the gem variety item is "Species", the processing unit 15 recognizes the location of "Species" before the target area A1 The title position (here as a gem variety title position), and then image recognition of the sub-region p1 (that is, the area below the gem variety title position) in the target area A1 corresponding to the gem variety title position, so Taking FIG. 3 as an example, the variety text data obtained by the processing unit 15 will be “Natural tourmaline”. The processing unit 15 obtains the origin text data, the cutting form text data, and the color text data in substantially the same manner as the variety text data, so it will not be explained one by one here. Taking FIG. 3 as an example, the origin text data obtained by the processing unit 15 in this step is "Mozambique" shown in the sub-region p2, and the cut-form text data is "faceted" shown in the sub-region p3 ", and the color text data is "blue" shown in the sub-region p4, but not limited to this.

After the processing unit 15 generates the image recognition result, it proceeds to step S5.

In step S5, the processing unit 15 compares each text data included in the image recognition result with the keywords included in the corresponding evaluation item, so as to select from the text items included in the evaluation item corresponding to the text data Among these keywords, one of the keywords matching the text data is selected. For ease of description, here, the four keywords that respectively correspond to the four strokes of data are taken as the four target keywords. More specifically, in this embodiment, the processing unit 15 compares the variety text data with the keywords of the gem variety item, and compares the origin text data with the keywords of the gem origin item Pair, compare the cut form text data with the keywords of the gem cut form item, and compare the color text data with the keywords of the gem color item to select the four target keywords . In the previous example, the four target keywords are, for example, "Natural tourmaline" included in the gem variety item, "Mozambique" included in the gem origin item, and "faceted" included in the gem cut form item, and The "blue" included in this gem color project is not limited to this. After the processing unit 15 selects the target keywords, step S6 follows.

In step S6, the processing unit 15 controls the output unit 12 to display a user interface that presents the options of the three auxiliary evaluation items (ie, the clarity item, the transparency item, and the chrominance item) , And set three target weighting coefficients corresponding to the clarity item, the transparency item and the chroma item respectively. More specifically, in this embodiment, the user operation interface includes, for example, three virtual sliders arranged longitudinally and in parallel, and the three virtual sliders respectively present the clarity options of the clarity item, the The transparency options of the transparency item and the chroma options of the chroma item, but not limited to this. The user operation interface allows the user to operate the virtual sliders in a touch manner to select one of the options of the auxiliary evaluation items, that is, the user can control the gem according to his own For the determination of brightness, transparency and chromaticity, one of the options of the clarity item, the transparency item and the chromaticity item is selected by the user operation interface.

In particular, in this embodiment, the three target weight coefficients are respectively preset as the three weight coefficients corresponding to the clarity option, the transparency option, and the chroma option representing “medium”, respectively. However, when the user selects one of the three auxiliary evaluation items through the user operation interface, the processing unit 15 will select the target weighting coefficient corresponding to the one of the three auxiliary evaluation items Update to the weight coefficient corresponding to the option selected by the user. Taking the clarity item as an example, the target weighting factor corresponding to the clarity item is preset to the weighting factor corresponding to the clarity option representing "medium" (that is, as shown in Table 1 above) "0.8") However, if the user selects the clarity option representing "very high" in the clarity item, the processing unit 15 will change the target weighting factor corresponding to the clarity item from "0.8" The weighting coefficient corresponding to the clarity option representing "very high" is updated (that is, updated to "1.0" shown in Table 1). The processing unit 15 controls the output unit 12 to display the user interface and set the three target weight coefficients, and then proceeds to step S7.

In step S7, when the processing unit 15 receives an evaluation result calculation instruction input by the user via the input unit 11, according to the weight value, the four weight parameters corresponding to the four target keywords and The three target weight coefficients execute the valuation algorithm included in the valuation rule data to calculate a valuation result, and control the output unit 12 to output the valuation result for user reference. In this embodiment, the valuation algorithm includes, for example, a lowest price estimation formula and a highest price estimation formula, and the valuation result includes, for example, a valuation range, and the valuation range includes a calculation based on the lowest price estimation formula The lower limit amount and the upper limit amount calculated according to the maximum price estimation formula, but not limited to this.

It is added that in this embodiment, the gem evaluation device 1 is implemented as a smart phone or a tablet computer, for example, and the gem evaluation device 1 is implemented by loading and running an application program, for example. Examples of this gem valuation method. In more detail, the gem appraisal device 1 may, for example, obtain the application from a computer-readable recording medium, and the computer-readable recording medium may be, for example, an optical disc or a memory card storing the application , A USB flash drive, a hard drive or other types of data carriers, but not limited to this. Alternatively, the gem appraisal device 1 may, for example, download an application product containing the application from the Internet (for example, from an application store) to obtain the application, but not limited to this. In particular, when an electronic device has hardware equivalent to the gem evaluation device 1 of this embodiment and the application program is loaded and executed, the application program can also enable the electronic device to complete the The gem valuation method.

Those with ordinary knowledge in the technical field of the present invention should understand that the descriptions of the evaluation items and the auxiliary evaluation items in this embodiment are merely examples, and are not intended to limit the scope of the implementation of the present invention. In other embodiments The specific types, contents and quantities of these valuation items and these auxiliary evaluation items can be freely planned and adjusted according to practical needs, and are not limited to this embodiment.

The differences between the second embodiment of the gemstone evaluation device 1 of the present invention and the first embodiment will be described below.

In the first embodiment, the storage unit 14 only stores a single certificate file template and a single piece of valuation rule data. However, in the second embodiment, the storage unit 14 stores multiple certificate file templates and respectively corresponds to Multiple valuation rule materials such as certificate file templates.

In the second embodiment, the certificate file templates respectively correspond to a plurality of different specific certificate types, and each certificate file template is related to the format of the certificate file belonging to the corresponding specific certificate type. For example, in addition to the "Gübelin" described in the first embodiment, the specific certificate types corresponding to the certificate document templates include, for example, "GRS", "GIA", "SSEF", " The types of gem identification certificates such as "Lotus" and "C. DUNAIGRE" are not limited to this. In addition, the content contained in each valuation rule data is set according to the corresponding certificate document template, for example, in the "Gübelin" type certificate file, "Species" is used to represent the item name of the gem variety item. However, in the "GRS" type of certificate document, "Identification" is used to represent the item name of the gem variety project. Therefore, the content of the valuation rule data will be based on the format of the corresponding certificate document template And different from each other.

Moreover, in the gem evaluation method implemented in the second embodiment, the processing unit 15 performs image recognition on the static image according to each of the certificate document templates in step S2 to determine the static image Whether there is the target area A1 that matches one of the certificate file templates, and when the judgment result of the processing unit 15 is yes, the certificate file template that matches the static image will be used as a target certificate file Template, and perform steps S4 to S7 according to the valuation rule data corresponding to the target certificate file template. In other words, in the second embodiment, when the processing unit 15 determines in step S2 that the target area A1 exists in the still image, it can also determine to which the certificate file presented in the target area A1 belongs A specific certificate file type corresponding to a certificate file template, and in subsequent steps S4 to S7, perform image recognition and evaluation according to the evaluation rule data corresponding to the target certificate file template.

In summary, by implementing the gem appraisal method, the gem appraisal device 1 of the present invention can first identify the target area A1 in the static image by image recognition, and then further identify the target area A1 in the certificate document template The weight value and the text data in the target area A1, and then, the gem appraisal device 1 can select the target key from the pre-stored keywords based on the text data and the evaluation rule data Word, and the evaluation result is calculated based on the weight value and the weight parameters corresponding to the target keywords for reference by the user, so the purpose of the invention can indeed be achieved.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention.
