DETAILED DESCRIPTION

[0062] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] Example

[0064] like Figure 1 As shown, an embodiment of the present invention provides a solar automatic planting flower pot device, including an external structure 1, a water storage structure 2, a small water pump 3, a pruning structure 4, a camera device 5 and a processor:

[0065] The camera device 5 is used to obtain plant images. The plant images are images of the side surfaces of the monitored plants.

[0066] The processor is used to execute the following method:

[0067] S101: extracting rhizomes based on the plant image to obtain a rhizome image. The rhizome image is an image containing only the rhizomes of the plant.

[0068] S102: Perform color detection based on the rhizome image and the plant image, and obtain the flower position through comparison.

[0069] Among them, color detection is performed to find objects different from branches and leaves through comparison.

[0070] S103: Obtaining a pruning position based on the flower position and the rhizome image.

[0071] Wherein, the pruning position is transmitted to the pruning structure.

[0072] The step of extracting rhizomes based on the plant image to obtain a rhizome image includes:

[0073] Based on the plant image and according to the characteristic that the plant root is connected to the soil, the root position is obtained through target detection.

[0074] Among them, according to the connection between the roots of plants and the soil, the plant images are reflected in images with different shapes and colors.

[0075] Among them, in this embodiment, the target detection is performed by the YOLOV5 algorithm, and multiple plant images are used as training images, and the corresponding plant root positions are used as annotations for training to obtain a target detection algorithm that can detect the root position.

[0076] Based on the plant image, the position of the plant stem is determined according to the pixels through a histogram to obtain a plant stem image; the plant stem image is the position containing branches and leaves in the image.

[0077] According to the root position, the skeleton of the stem position in the stem image is adjusted to obtain the root image.

[0078] Through the above method, the two-dimensional image is used to find the bottom rhizome position and adjust the rhizome position from bottom to top.

[0079] Optionally, the step of predicting the stem position according to the plant image by using a histogram to obtain the stem image includes:

[0080] According to the plant image, a histogram is constructed to obtain a plant array. The plant array is a two-dimensional array; the elements in the plant array are the same as the information in the histogram.

[0081] The histogram and plant array are arranged in order from low to high according to the pixel values ​​of the colors.

[0082] The values ​​in the image in the histogram represent the number of pixels corresponding to each pixel value.

[0083] Among them, judging pixels according to the histogram is equivalent to judging colors, because the colors of branches and leaves are in a fixed range.

[0084] A color window is established. The color window represents a fixed number of pixel values.

[0085] The color window represents grouping the colors in the histogram, ie, the plant array.

[0086] Among them, the color window in this embodiment is 4.

[0087] According to the color window, sliding is performed with a step size of 1 to obtain multiple pixel groups.

[0088] The pixel groups represent adjacent positions, that is, adjacent colors.

[0089] A plurality of pixel quantities are obtained by adding the number of pixels in a plurality of pixel groups for a plurality of times.

[0090] The pixel quantity represents the quantity of similar colors, such as the quantity of green in branches and leaves.

[0091] Compare multiple pixel quantities, find a pixel quantity that is greater than other pixel quantities, and obtain the optimal pixel quantity.

[0092] The position where the pixel value corresponding to the optimal pixel quantity in the plant image is located is set to 1, and the other positions are set to 0, so as to obtain a plant stem image.

[0093] The plant stem image is an image that roughly obtains the locations of plant branches and leaves.

[0094] Optionally, extracting the skeleton of the stem position in the stem image according to the root position to obtain the root and stem image includes:

[0095] Extend the root position by one eighth of itself to obtain the extended rhizome position.

[0096] The left-right ratio is obtained according to the quotient of the extended root center line to the left boundary and the right boundary of the extended stem position.

[0097] The left-right ratio is obtained by subtracting the horizontal coordinate of the left boundary of the extended stem position from the horizontal coordinate of the center line of the root and dividing it by the vertical coordinate of the left boundary of the extended stem position from the horizontal coordinate of the center line of the root.

[0098] The skeleton of the plant stem image is extracted according to the left-right ratio to obtain a rhizome image.

[0099] By using the above method, the root position and the plant stem image are matched, so that the skeleton of the plant stem can be obtained more accurately during skeleton extraction.

[0100] Optionally, extracting a portion of the skeleton through a histogram according to the plant image to obtain a plant stem image includes:

[0101] According to the left-right ratio, the number of left corrosion times and the number of right corrosion times are obtained;

[0102] The left boundary of the stem position in the stem image is eroded multiple times according to the left erosion times by using the erosion boundary algorithm.

[0103] The right boundary of the stem position in the stem image is eroded multiple times according to the right erosion times through the erosion boundary algorithm.

[0104] The corrosion boundary algorithm described in this embodiment is the K3M algorithm.

[0105] The root image is obtained by alternately performing left erosion and right erosion multiple times.

[0106] Through the above method, the border is generally eroded at the same time, but due to the proportion problem, after the left side is eroded a certain number of times, the right side is eroded.

[0107] Optionally, performing color detection based on the rhizome image and the plant image and obtaining the flower position by comparison includes:

[0108] The plant image is detected to obtain an initial detected flower position and an initial detected flower color.

[0109] In this embodiment, the YOLOV5 target detection model trained by using multiple flower images multiple times is used to detect the flower position.

[0110] The flower colors are divided into 7 categories: red, orange, yellow, green, cyan, blue, and purple, and are marked as 1, 2, 3, 4, 5, 6, and 7. 1 corresponds to red, 2 corresponds to orange, 3 corresponds to yellow, 4 corresponds to green, 5 corresponds to cyan, 6 corresponds to blue, and 7 corresponds to purple.

[0111] Based on the color of the flower initially detected and the color corresponding to the pixel quantity when the plant stem image is obtained, it is determined whether the colors are similar.

[0112] Among them, according to the pixel value corresponding to the pixel quantity when obtaining the plant stem image, that is, the RGB value, the color is classified into red, orange, yellow, green, cyan, blue and purple according to the color comparison table to determine whether it is the same as the category of the flower color initially detected.

[0113] If the colors of the initially detected flower position and the color position are not similar, the flower position is obtained. The flower position is the initially detected flower position.

[0114] Through the above positions, sometimes the shape of branches and leaves is similar to that of flowers, which may lead to misjudgment. Judgment is made through color contrast and alignment.

[0115] Optionally, obtaining the pruning position according to the flower position and the rhizome image includes:

[0116] The trimming positions include a trimming height position and a trimming level position;

[0117] Get the pruning height. The pruning height represents the preset height of the branches and leaves after pruning.

[0118] In this embodiment, the trimming height is set to 1 / 10 of the flower pot height, which is 5 cm in this embodiment.

[0119] According to the vertical position of the flower, the flower height is obtained.

[0120] The center point position and height of the flower position are obtained. The center point position of the flower position plus half of the height is added to obtain the flower height.

[0121] The flower height is the height of the highest flower among the multiple flowers.

[0122] If the trimming height is less than the flower height, the trimming height position is set to the flower height; if the trimming height is greater than or equal to the flower height, the trimming height position is set to the trimming height.

[0123] According to the rhizome image at the pruning height position, find the rhizome position and set the rhizome position as the pruning level position.
