This is, in the present invention, the final remaining amount, that is, the final remaining weight, is the weight of the solid food (lf_s) excluding the weight of the liquid food (lf_l) from the weight of the remaining (lf) accommodated in the leftover accommodating part 50 This is to calculate the weight of the final remainder made of the solid food material lf_s except for the liquid food material lf_l from the remainder lf.

Meanwhile, at this time, the image analysis unit 510 determines that at least one of the solid and liquid food ingredients lf_s and lf_l included in the leftover lf as described above is included, as shown in FIG. 9 . , it can be performed by analyzing the degree of clustering of the ingredients included in the leftover lf.

For example, as shown in FIG. 9, when comparing the cluster diagram of the solid food material (lf_s) and the liquid food material (lf_l) accommodated in the leftover container 50, the solid food material (lf_l) rather than the liquid food material (lf_l) This is because the clustering degree of lf_s) may be high. Accordingly, in the image analysis unit 510, the solid and liquid food ingredients lf_s, lf_l) may be determined to include at least one.

Meanwhile, in this case, the image analysis unit 510 may extract the boundary of the food ingredients included in the leftover lf in order to analyze the clustering degree as described above.

Here, the boundary of the food material may mean the outermost boundary bt in which the solid food material lf_s is clustered, as shown in FIG. 9 , and the boundary of each solid food material lf_s constituting the cluster It can also mean (bt).

Accordingly, the image analysis unit 510 extracts the boundary of the food ingredients included in the leftover food lf from the upper image of the leftover food lf photographed through the image capturing unit 200 to obtain the cluster diagram. By analyzing , it can be determined that the remainder lf includes at least one of the solid food lf_s and the liquid food lf_l. That is, the image analysis unit 510 determines, in the upper image of the leftover lf, a food material in a region having a relatively high degree of clustering as a solid food material lf_s, and selects a food material in an area having a relatively low degree of clustering. It can be determined as liquid food (lf_l).

On the other hand, as described above, in the image analysis unit 510 , based on the degree of clustering, the state of the leftovers accommodated in the leftovers accommodating part 50 , that is, whether it is a solid food (lf_s) or a liquid food (lf_l) However, in determining the recognition by distinction, in determining the solid and liquid food ingredients lf_s and lf_l included in the leftover lf, a situation may arise where it is difficult to make a clear determination only with the clustering degree as described above.

In this case, the leftover state determining unit 530 to be described later may control the remaining leftover state discrimination unit 700 to be described later so that the state of the remaining leftover food lf accommodated in the leftover food accommodating unit 50 is distinguished. This will be described later in more detail.

On the other hand, according to an embodiment, the Nth tea remainder (lfNa, see FIG. 21) and the N+1th tea remainder (lfN+1a, see FIG. 22) are sequentially accommodated in the leftover accommodating unit 50. can be assumed. Here, the N-th tea leftover (lfNa, see FIG. 21) may be defined as the N-th leftovers accommodated in the leftover accommodating part 50, wherein the N+1th tea leftovers (lfN+1a, 22) may be defined as leftovers that are accommodated in the leftovers accommodating part 50 in a lower order than the Nth tea leftovers lfNa (refer to FIG. 21).

More specifically, referring to FIG. 21 , the N-th tea remainder lfNa may be accommodated in the remainder accommodating part 50 first.

In this case, the image analysis unit 510 may control to photograph (sh) the N-th residual lfNa through the image photographing unit 200 .

Thereafter, referring to FIG. 22 , an N+1th order leftover lfN+1a may be accommodated in the leftover accommodating part 50 .

At this time, referring to FIG. 23 , the image analysis unit 510 is configured to perform a difference set ( It is possible to control to irradiate the illumination lg to the area corresponding to df1).

Accordingly, as shown in FIG. 23 , the illumination lg may be irradiated to the region corresponding to the difference set df1 to be bright (br), but other regions may be dark (dk).

Accordingly, referring to FIG. 24 , the image analysis unit 510 captures (sh) an area corresponding to the difference set df1 irradiated with the illumination lg through the image capturing unit 200 . By controlling, an image of a region corresponding to the difference set df1 may be acquired.

According to an embodiment of the present invention, as shown in FIG. 22 , the Nth tea remainder lfNa and the N+1th tea remainder lfN+1a are sequentially disposed in the remainder accommodating part 50 . When received and the Nth and N+1th residuals lfNa, lfN+1a are mixed to form a region corresponding to the intersection it1 of the two, in the region corresponding to the intersection it1 This is in consideration of the difficulty in identifying residues.

In other words, according to an embodiment of the present invention, when the N-th tea remainder lfNa and the N+1th tea remainder lfN+1a are sequentially accommodated in the leftover accommodating part 50 , the remainder By excluding the region corresponding to the intersection (it1) formed by mixing between the two, a clear weight of the remaining residue is calculated.

However, the above-described embodiment may be limited to a case in which the area of the region corresponding to the intersection it1 as described above is formed to be less than a predetermined standard.

Here, the term "less than a predetermined criterion" may be understood as a concept including a case in which the area of the region corresponding to the intersection it1 is less than the area of the region corresponding to the difference set df1.

Therefore, referring to FIG. 25 , according to another embodiment, when the area of the region corresponding to the intersection it2 is greater than or equal to the area of the region corresponding to the difference set df2, the image analysis unit 510, Through the lighting unit 270 , it is possible to control to illuminate both the region corresponding to the intersection it2 and the region corresponding to the difference set df2 .

In addition, by controlling to photograph the area corresponding to the intersection (it2) and the difference (df2) irradiated with the illumination through the image capturing unit 200, the intersection (it2) and the difference (df2) corresponding to the An image of the area can be acquired.

According to an embodiment of the present invention, as shown in FIG. 25 , the Nth tea remainder lfNb and the N+1th tea remainder lfN+1b are sequentially disposed in the leftover accommodating part 50 . The region corresponding to the intersection it2, which is accommodated and formed by mixing the Nth and N+1th residuals lfNb and lfN+1b, corresponds to the N+1th residual lfN+1b. When it is greater than or equal to the region corresponding to the difference set df2 of the N-th residual lfNb, a relatively large amount of residual weight included in the region corresponding to the intersection it2 is considered.

On the other hand, in contrast to this, referring to FIG. 26 , according to another embodiment, the N-th and N+1-th residuals lfNc and lfN+1c do not mix, so that the intersections it1 and it2 as described above are not formed. case can be imagined.

In this case, the image analysis unit 510 controls to illuminate each of the N-th residual lfNc and the N+1-th residual lfN+1c through the lighting unit 270, and the The image capturing unit 200 may control to photograph the N-th and N+1-th residuals lfNb and lfN+1b respectively illuminated as described above.

On the other hand, at this time, the illumination irradiation and shooting of the image analysis unit 510 as described above, when the N-th residual remainder lfNc is accommodated in the remainder accommodating unit 50, the photographing is performed after irradiating the illumination, and then the When the N+1th residual part lfN+1c is accommodated in the residual part accommodating part 50, it may be understood as a concept including the photographing after irradiating the illumination.

Alternatively, according to an embodiment, the illumination and photographing of the image analysis unit 510 as described above is the N-th and N+1-th residuals (lfNb, lfN+1b) in the residual accommodating part 50 . After all of these are accommodated, it may be a concept including photographing at once after irradiating the illumination to both the N-th and N+1-th residuals lfNb and lfN+1b. This is because, as described above, the intersections it1 and it2 are not formed because the Nth and N+1th residuals lfNc and lfN+1c do not mix.

Meanwhile, each of the steps described above is not limited to the above-described order, and the order may be changed and/or omitted if necessary.

For example, as described above, step S130 may be omitted, and for example, at least any two or more steps among steps S110 to S150 may be simultaneously performed.

Hereinafter, with reference to FIGS. 19 to 26 , in the above-described step S110 , the Nth tea remainder lfNa and the N+1th tea remainder lfN+1a are sequentially disposed in the leftover accommodating unit 50 . Let us assume a case where it is accepted as

Referring to FIG. 20 , the above-described step S110 includes a step of accommodating the Nth tea remainder lfNa (S111), a step of photographing the Nth tea remainder lfNa (S112), and the N+1th tea remainder lfN. Step (S113) of accommodating +1a), irradiating illumination to an area corresponding to the difference set of the N-th residual (lfN) with respect to the (N+1)-th residual (lfN+1a) (S114), and lighting It may include at least any one of the step (S115) of photographing the irradiated area.

Hereinafter, each step is described.

Step S111

Referring to FIG. 21 , in step S111 , the leftover accommodating part 50 may receive the Nth tea leftover lfNa. Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

Step S112

Referring to FIG. 21 , in step S112 , the image analysis unit 510 may control to photograph (sh) the N-th residual remainder lfNa through the image photographing unit 200 . Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

Step S113

Referring to FIG. 22 , in step S113 , the leftover accommodating part 50 may accommodate the N+1th order leftover lfN+1a. In other words, the N-th residual remainder lfNa of step S111 and the N+1-th residual lfN+1a of the present step are sequentially accommodated in the leftover accommodating unit 50 . Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

Step S114

Referring to FIG. 23 , in step S114 , the image analyzer 510 may perform a difference between the N+1th residual lfN+1a and the N+1th residual lfNa through the lighting unit 270 . It is possible to control to irradiate the light lg to the area corresponding to the set df1.

Accordingly, as shown in FIG. 23 , the illumination lg may be irradiated to the region corresponding to the difference set df1 to be bright (br), but other regions may be dark (dk).

Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

Step S115

Referring to FIG. 24 , in step S115 , the image analysis unit 510 captures an area corresponding to the difference set df1 irradiated with the illumination lg through the image capturing unit 200 (sh) By controlling to do so, an image of a region corresponding to the difference set df1 can be obtained.

As described above, as described above, the Nth tea remainder lfNa and the N+1th tea remainder lfN+1a are sequentially accommodated in the remainder accommodating unit 50 , and the Nth and Nth tea remainders lfN+1a are sequentially accommodated. When the +1-order residuals lfNa and lfN+1a are mixed to form a region corresponding to the intersection it1 of the two, the difficulty in determining the residual in the region corresponding to the intersection it1 is taken into consideration. Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

Meanwhile, in step S113 described above, it is assumed that the area of the region corresponding to the intersection it1 is less than the area of the region corresponding to the difference set df1.

Hereinafter, steps S113b and S113c, which are modified examples of the above-described step S113, will be described.

step S113b

In step S113b, as in step S113 described above, the leftover accommodating part 50 may accommodate the N+1th order leftover lfN+1b.

Meanwhile, referring to FIG. 25 , unlike step S113 described above in this step, when the leftover accommodating part 50 accommodates the N+1th order remainder lfN+1b, the intersection it2 The area of the region corresponding to df2 may be greater than or equal to the area of the region corresponding to the difference set df2.

Accordingly, in step S114b (not shown), which is a modification step of step S114 described above, the image analysis unit 510 performs an area corresponding to the intersection it2 and the difference set df2 through the illumination unit 270 . It can be controlled to illuminate all areas corresponding to .

In addition, in step S115b (not shown), which is a modification step of step S115 described above, the image analysis unit 510 performs an intersection (it2) and a difference (df2) to which the illumination is irradiated through the image photographing unit 200 . By controlling to photograph the area corresponding to , images of the area corresponding to the intersection it2 and the difference set df2 may be obtained.

As described above, the region corresponding to the intersection it2 formed by mixing the N-th and N+1-th residuals lfNb and lfN+1b is the N+1-th residual lfN+1b. ), when it is greater than or equal to the region corresponding to the difference set df2 of the N-th residual remainder lfNb, a relatively large amount of residual weight included in the region corresponding to the intersection it2 is considered. Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

step S113c

In step S113c, as in step S113 described above, the leftover accommodating part 50 may accommodate the N+1th order leftover lfN+1c.

On the other hand, referring to FIG. 26 , unlike step S113 described above in this step, when the leftover accommodating part 50 accommodates the N+1th order remainder lfN+1c, the Nth order and Since the N+1th order residues lfNc and lfN+1c are not mixed, the intersections it1 and it2 as described above may not be formed.

Accordingly, in step S114c (not shown), which is a modified step of step S114 , the image analyzer 510 performs the Nth residual lfNc and the N+1th residual residual lfNc through the lighting unit 270 . (lfN+1c) can be controlled to illuminate each.

In addition, in step S115c (not shown), which is a modification of step S115 described above, the image analysis unit 510 is irradiated with the Nth and Nth lights, respectively, as described above through the image capturing unit 200 , respectively. It can be controlled to shoot the first residuals (lfNb, lfN+1b).

This is because, as described above, the intersections it1 and it2 are not formed because the Nth and N+1th residuals lfNc and lfN+1c do not mix. Since this overlaps with the previous embodiment, reference will be made to the above-described embodiment.

It goes without saying that the above-described modified steps of the present invention may be performed together with steps S110 to S150 described above.

As mentioned above, although the present invention has been described in detail using preferred embodiments, the scope of the present invention is not limited to specific embodiments and should be construed according to the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
