In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0025] Figure 1 The schematic diagram of the structure of the vegetation coverage calculation device provided by the embodiment of the utility model in the first state is illustrated. Figure 2The schematic diagram of the structure of the vegetation coverage calculation device provided by the embodiment of the utility model in the second state is illustrated.
[0026] Reference Figure 1 or Figure 2 , a vegetation coverage measuring device provided by an embodiment of the utility model includes a carrier 100 and a plurality of marking members 200. The carrier 100 includes a transparent measuring area and a storage area. The transparent measuring area is provided with a plurality of marking parts, and the plurality of marking parts are arranged in an array distribution; a plurality of marking members 200 are movably arranged in the storage area, and the marking members 200 are arranged one by one corresponding to the marking parts. The transparent measuring area can be understood as a region where the material is made of a transparent material. The marking part can be a transparent measuring area evenly divided by grid lines, and each small grid represents a marking part.
[0027] In the above structure, since the transparent measurement area is a transparent structure, the carrier with vegetation image information can be placed below the transparent measurement area, and then the image of the vegetation can be observed through the transparent measurement area, so that the image of the vegetation is projected on the marking part on the transparent measurement area. The marking part is arranged in an array, and then the marking part can quantify the area of the transparent measurement area, that is, divide and quantify the image area of the vegetation. When it is necessary to calculate the coverage of the vegetation, it is only necessary to calculate the number of marking parts occupied by the projection of the vegetation image on the transparent measurement area (this number can be marked as a), and calculate the number of marking parts occupied by the projection of the vegetation-covered part on the vegetation image on the transparent measurement area (this number can be marked as b), or the number of marking parts occupied by the projection of the non-vegetation-covered part on the vegetation image on the transparent measurement area (this number can be marked as c). The utility model is also provided with a marking part 200, which can be used to mark the number of marked parts of the vegetation-covered part on the vegetation image or the non-vegetation-covered part on the vegetation image that have projections in the transparent measurement area, thereby distinguishing the two, so that the calculation of the number of the two is more convenient. The utility model quantifies the coverage area of vegetation, and only needs to obtain an additional top-view image of the vegetation, which greatly improves the convenience and accuracy of vegetation coverage measurement.
[0028] It should be noted that the vegetation image is a top view of the vegetation field, and when the projection area of the vegetation-covered part on the vegetation image on the marked part occupies half or more of the area of a certain marked part, the marked part is included in b; when the projection area of the vegetation-covered part on the vegetation image on the marked part occupies less than half of the area of the marked part, the marked part is included in c. Vegetation coverage = b / a×100%, or vegetation coverage = 1-c / a×100%.
[0029] Reference Figure 1In some embodiments of the present invention, the marking parts are provided with limiting parts 300 in one-to-one correspondence, and the limiting parts 300 are used to limit the marking parts 200.
[0030] Specifically, the marking member 200 can be a spherical object, a columnar object or a granular object of other shapes. It should be noted that the shapes and sizes of the multiple marking members 200 can be the same, which is convenient for counting. And the area of the marking member 200 in the top view direction is smaller than the area of the marking portion in the top view direction. The limiting portion 300 can specifically be a groove or a hole. It should be noted that the shape of the limiting portion 300 needs to be compatible with the shape of the marking member 200 so that the marking member 200 can be limited at the limiting portion 300. The limiting portion 300 can specifically be an arc-shaped groove or a cylindrical through hole.
[0031] By setting the limiter 300, the marking part 200 can be fixed on the marking part, making the marking part more conspicuous and easier to distinguish than other unfixed marking parts, so that the area of the vegetation-covered part and the non-vegetation-covered part can be quickly identified. Secondly, the design of the limiter 300 can prevent the marking part 200 from moving or falling off inadvertently, thereby avoiding marking errors or confusion caused by misoperation. This not only enhances the stability of the marking, but also improves the safety of use, avoiding potential risks caused by marking failure or misjudgment.
[0032] Reference Figure 1 In some embodiments of the present invention, the vegetation coverage measurement device further includes a marker extractor 600, which is used to move the marker 200 to the limiting portion 300. The marker extractor 600 includes a magnetic rod 610 and a connecting rope 620, one end of the connecting rope 620 is connected to the carrier 100, and the other end is connected to the magnetic rod 610.
[0033] Specifically, the preparation material of the marking member 200 can be steel, iron and other materials that can be attracted by a magnet. In the above structure, when the marking member 200 needs to be placed in the limit portion 300, it is only necessary to contact the magnetic bar 610 with the marking member 200, and under the action of the magnetic force, the two are magnetically attracted, and then the marking member 200 is transferred to the limit portion 300 and put down. The magnetic bar 610 can quickly attract and extract the marking member 200, which greatly simplifies the operation process and improves work efficiency. Compared with manual operation or other mechanical operations, the use of the magnetic bar 610 is faster and more accurate, reducing the operation time and labor costs. Especially when extracting smaller or difficult-to-grasp marking members 200, the use of the magnetic bar 610 can be more convenient and quick. By setting the connecting rope 620, the magnetic bar 610 can be always connected to the carrier 100, avoiding the risk of losing the magnetic bar 610. It should be noted that the length of the connecting rope 620 needs to meet the entire range of motion of the magnetic rod 610, so that the magnetic rod 610 can place the marking member 200 at any limiting portion 300. In other possible embodiments, a groove for placing the magnetic rod 610 can also be provided on the carrier 100. In this way, when the magnetic rod 610 is not needed, the magnetic rod 610 can be stored in the groove to keep the entire device neat.
[0034] Reference Figure 1 In some embodiments of the utility model, the carrier 100 includes a bottom plate 110 and multiple side plates 120, and the multiple side plates 120 cooperate with the bottom plate 110 to form a container with an open top, and the bottom wall of the container is formed by the bottom plate 110; a partition is provided in the container, and the partition divides the interior of the container into a first cavity and a second cavity, the transparent measuring area is located at the bottom of the first cavity, and the storage area is located in the second cavity.
[0035] Specifically, the bottom plate 110 and the side plate 120 are both rectangular plate structures, and there are four side plates 120, which are respectively fixedly mounted on the four sides of the bottom plate 110, thereby forming a rectangular container with an opening at the top. This arrangement can prevent the marking member 200 from detaching from the carrier 100, and prevent the marking member 200 from accidentally rolling off and being lost.
[0036] Reference Figure 1 In some embodiments of the present invention, a plurality of supporting members 130 are provided at the bottom of the base plate 110, and a space is formed between the plurality of supporting members 130 and the base plate 110, and the space is used to place a carrier provided with vegetation image information.
[0037] Specifically, there are four support members 130, which are fixedly mounted at the four corners of the bottom of the base plate 110, respectively. The support members 130 play the following role on the one hand, and on the other hand, form a space for placing a carrier with vegetation image information at the bottom of the base plate 110. In this way, when it is necessary to measure the vegetation image, it is only necessary to place the carrier of the image device in the space, and make the range of the vegetation image to be measured overlap with at least part of the marking part of the transparent measurement area, so that the vegetation image can be projected onto the marking part, which is convenient for calculating the total number of marking parts occupied by the vegetation image and the number of marking parts occupied by the vegetation part, thereby facilitating the calculation of vegetation coverage. In some possible embodiments, the support member 130 can also be designed to be height-adjustable. By adjusting the height of the support member 130, the area of the vegetation image in the transparent measurement area is changed, and the projection area of the vegetation image on the transparent measurement area is adjusted to the most convenient area for measuring the marking part. Because the size of the image is different from the size of the marking part, the height can be adjusted to make the edge of the image and a certain marking part area that is easy to calculate easy to align, so that the number of marking parts is easy to calculate.
[0038] Reference Figure 1 In some embodiments of the present invention, the bottom wall of the second cavity is provided with an inclined plate 400, which is inclined from one end of the second cavity to the other end, and the marking member 200 is movably provided on the cover plate 500. The marking members 200 are arranged in the second cavity in a first rectangular array, and the second cavity is provided with a first scale, which is used to identify the number of rows and columns of the first rectangular array.
[0039] In the above structure, by setting the inclined plate 400, the weight of the marking member 200 can automatically roll and gather at one end of the first cavity. This makes it easy to arrange the marking members 200, and then to count the marking members 200. By calculating the size of the marking members 200, the second cavity is designed to enable the marking members 200 to be arranged in a rectangular array inside it. That is, the first cavity is rectangular, and the length and width of the second cavity are integer multiples of the diameter of the marking member 200. In this way, when the marking member 200 is placed in the second cavity, the marking member 200 will automatically be arranged in a matrix form along the first end of the second cavity under the action of gravity. And the number of marking members 200 in the second cavity can be quickly calculated through the first scale.
[0040] Reference Figure 1 In some embodiments of the present invention, a cover plate 500 is provided on the top of the container, and the cover plate 500 is used to close the container.
[0041] Specifically, the cover plate 500 is fixedly mounted on the top of the container, and the bottom plate 110, the side plate 120 and the cover plate 500 are all transparent parts, made of transparent materials. When using the device, since the bottom plate 110, the side plate 120 and the cover plate 500 are all transparent parts, the internal situation of the device can be observed from the outside, and then the marking piece 200 can be transferred from the outside of the cover plate 500 through the magnetic rod 610, which is not only convenient to use, but also can well protect the internal structure of the device.
[0042] It should be noted that Figure 1 The cover plate 500 shown in FIG. 1 is a partial view of the cover plate 500, and the cover plate 500 actually closes the entire top of the carrier 100. In other possible embodiments, the connection between the carrier 100 and the cover plate 500 can be detachably connected by buckles. When it is necessary to repair the inside of the device, the cover plate 500 is removed.
[0043] Reference Figure 1 In some embodiments of the present invention, the marking parts are arranged in a second rectangular array in the transparent measuring area, and the transparent measuring area is provided with a second scale, and the second scale is used to identify the number of rows and columns of the second rectangular array.
[0044] In the above structure, the marking parts are arranged in the form of a second rectangular column. This arrangement can facilitate the counting of the marking parts, so that the total number of marking parts occupied by the vegetation image can be quickly calculated. Secondly, by setting the second scale, the number of marking parts can be more conveniently calculated.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
