[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0058] Embodiment one

[0059] Please refer to Figure 1 A step flow chart of a forest resource asset determination method provided by the present application, comprising steps 101 to 105, each step is specifically as follows:

[0060] Step 101, obtaining target latitude and longitude information of a forest resource asset to be detected, and collecting segmented remote sensing images of a target forest area range within the target latitude and longitude information by a UAV to obtain multiple target remote sensing images.

[0061] In the embodiment, the step 101 specifically comprises: step 1011, determining a maximum collection range according to a model of the UAV, dividing the target latitude and longitude information into multiple latitude and longitude ranges according to the maximum collection range and arranging them in sequence; step 1012, controlling the UAV to collect segmented remote sensing images according to the arranged latitude and longitude ranges in sequence and transmitting the collected target remote sensing images in real time; step 1013, identifying resource boundary features of the target remote sensing images transmitted back in real time, and determining the resource boundary as an end point of the target remote sensing image of the current segment when judging that a distance value between the identified resource boundary and the target remote sensing image of the next segment is less than a preset distance value; and step 1014, re-dividing the latitude and longitude ranges which have not been collected into images according to the maximum collection range and arranging them in sequence until the end point of each target remote sensing image is determined.

[0062] Specifically, in order to solve the problem of inaccuracy in measuring and calculating between image acquisition and long continuous images in the prior art, we use a segmented remote sensing image acquisition method during image acquisition by a UAV. In actual operation, the target latitude and longitude information is used for preliminary segmentation. However, considering that in actual application, the same segment may be divided into two adjacent segments due to the obvious feature boundary of forest resources, which may affect the accuracy of the data, we also need to consider the distance value between the resource boundary of the current segmented image and the target remote sensing image of the next segment during segmentation of the segmented image. That is, when the distance between the forest resource boundary in the current segmented image and the next image is already "very short", the image acquisition for the current segment is stopped at this time, and the current forest resource boundary is taken as the end point of the current segment. In the subsequent forest resource feature collection, the next segmented image is collected until all the forest resource images are collected.

[0063] Step 102, respectively, for each segment of the target remote sensing image feature recognition, mark the resource feature in the target remote sensing image, and get the corresponding resource feature in each segment of the target remote sensing image.

[0064] In the first aspect of the embodiment, the step 102 specifically includes: respectively transmitting each segment of the target remote sensing image as an input image to a preset resource feature recognition model for resource feature recognition, to obtain an output image, wherein the resource feature in the target remote sensing image is marked in the output image; wherein the preset resource feature recognition model is used to identify the resource feature in the input image and determine the resource type, and output the output image marked with the resource feature and the corresponding resource type.

[0065] In the second aspect of the embodiment, the construction process of the preset resource feature recognition model specifically includes: obtaining a historical remote sensing image, marking the forest resource feature in the historical remote sensing image to generate first marking information; determining the corresponding resource type according to the marked forest resource feature to generate second marking information, and associating the first marking information and the second marking information and marking them in the historical remote sensing image to generate a final remote sensing image; constructing an initial recognition model through a neural network algorithm, inputting the final remote sensing image into the initial recognition model for training until the training times reach a times threshold, to obtain a trained recognition model; inputting the historical remote sensing image into the trained recognition model for testing until the test success rate reaches a success threshold to generate a resource feature recognition model.

[0066] Specifically, in order to accurately identify the resource features in the target remote sensing image, including the corresponding resource type, we need to construct and train the model, use the labeled forest resource features in the historical remote sensing image, and determine the corresponding resource type, and then mark the input image of the model, which can accurately train the identification model we need.

[0067] Step 103, respectively calculate the area size of each resource feature in the target remote sensing image where it is located, get the area value, and calculate the resource value corresponding to each resource feature according to the area value.

[0068] In this embodiment, the step 103 specifically includes: step 1031, respectively determine the center point of each resource feature, take the center point as the center of the circumscribed circle, determine the circumscribed circle of the resource feature, and determine the area value corresponding to the resource feature according to the area of the circumscribed circle; Step 1032, according to the output labeled resource feature and its corresponding resource type of the preset resource feature identification model, determine the target resource type of the resource feature corresponding to the circumscribed circle; Step 1033, according to the target resource type, determine the preset weight value, calculate the product of the area value and the preset weight value as the resource value corresponding to the resource feature.

[0069] Specifically, in order to accurately identify the resource value corresponding to each resource feature, we use the calculation method of the circumscribed circle, and combine the product of the preset weight values corresponding to different resource types, which can accurately express the resource value of different types of resource features, so as to facilitate the total value calculation in the subsequent process.

[0070] Step 104, according to the target latitude and longitude information, arrange all the target remote sensing images in order, and respectively determine the reference resource feature point according to the resource feature marked in each section of the target remote sensing image, and sequentially fuse all the target remote sensing images arranged in order according to the reference resource feature point, to get a long continuous remote sensing image.

[0071] In this embodiment, the step 104 specifically includes: step 1041, respectively determine the end point of the current section of the target remote sensing image in the resource feature marked in each section of the target remote sensing image as the first fusion point; Step 1042, determine the resource boundary corresponding to the end point of the current section of the target remote sensing image in the adjacent next section of the target remote sensing image as the second fusion point; Step 1043, align the first fusion point and the second fusion point as the reference resource feature point, and fuse the current section of the target remote sensing image with the adjacent next section of the target remote sensing image, until all the target remote sensing images are sequentially fused to complete, to get a long continuous remote sensing image.

[0072] Specifically, in order to realize the calculation of long continuous images, the most important step after accurately identifying each segmented image is to fuse the segmented images. In actual application, by determining the fusion points, the reference resource feature points are aligned, the current target remote sensing image and the adjacent next target remote sensing image are fused, until all target remote sensing images are sequentially fused to obtain long continuous remote sensing images.

[0073] In step 105, the forest resource asset total value of the target forest region range is calculated according to the resource value corresponding to each resource feature in the long continuous remote sensing image.

[0074] In the embodiment, the calculation formula of the forest resource asset total value is:

[0075]

[0076] Wherein, S0 is the forest resource asset total value; S i is the resource value corresponding to the i th resource feature, k i is the preset type threshold value corresponding to the resource type of the i th resource feature; i is the resource feature, and n is the total number of resource features.

[0077] Specifically, in the actual calculation process, the above formula can objectively and accurately determine the forest resource asset total value of the target forest region range.

[0078] The technical scheme of the present application can accurately calculate the forest resource asset total value of the target forest region range by segmenting the target forest region range for remote sensing image acquisition, sequentially fusing all target remote sensing images arranged in sequence after calculating the resource value corresponding to each resource feature, thereby solving the technical problem that the inaccuracy of image acquisition and long continuous image calculation in the prior art leads to the strategy of using big data to measure part of the forest region only in a small range, and the forest range with large area and wide region cannot be accurately measured. For the forest range with large area and wide region, the actual situation of forest resource assets can be effectively, quickly and accurately determined, which provides strong data support for ecological environment protection.
