Detailed Description
According to a first embodiment of the present invention, referring to fig. 1, the present invention claims a method for processing an ArcGIS and photoshop automatic linkage image, which is characterized by comprising the steps of:
s1, acquiring images selected by a user and drawn rectangular partitions in an Arcmap plug-in interface;
s2, the drawn data of the rectangular partition are stored in a list and displayed in a form control, partition data drawn by a user are encoded into RECTANGLEDATA types of examples, and metadata of each cut image partition are stored;
s3, cutting the images according to the partitions, generating temporary image data, calling a cutting tool of the ArcGIS by the plug-in unit, cutting the images according to the rectangular partitions, and storing cutting results as temporary files;
S4, importing the temporary image data into Photoshop, and tracking the editing state, and starting a file system monitor to track the editing operation of a user after the temporary image data is automatically imported into Photoshop;
S5, detecting the operation state of the user on the temporary image data in the Photoshop, performing image mosaic after all the temporary images of the partitions are stored, replacing the corresponding areas in the original image with the images stored in the Photoshop, monitoring the change of the Photoshop file through FILESYSTEMWATCHER, detecting the change of the file state after the user finishes editing and storing the temporary images, and triggering the subsequent image mosaic operation.
Further, step S1 further includes:
S1.1, a remote sensing image is represented as IRASTERLAYER objects, wherein the IRASTERLAYER objects are objects used for representing raster data layers in ESRI ARCGIS software; IRASTERLAYER contain spatial references to raster data, pixel value types, and other display and analysis related attributes;
S1.2, after a user draws a rectangular partition in a plug-in interface, the plug-in creates a IEnvelope object according to the space range of the rectangular partition; the IEnvelope object is an interface defined in ArcGIS, and is used for describing a minimum bounding box of a rectangular area, where the minimum bounding box contains minimum and maximum X, Y coordinate values in a coordinate system, and determining the precise position and range of the clipping area.
Further, step S2 further includes:
the partition data drawn by the user is encoded into RECTANGLEDATA class examples, and metadata of each clipping image partition is stored, wherein the metadata at least comprises:
ISSELECTED: boolean type Boolean, indicate whether the partition is selected for processing;
ID: string, providing a unique identifier for each partition;
width and Height: floating point number Double, the width and height of the designated clipping region;
Status: string, describing the processing state of the partition, including at least "unprocessed", "in-process", "completed";
Area: floating point number Double, the area of rectangular area calculated;
PixelCount: integer intelger, number of pixels in clipping region;
pEnvelope: IEnvelope types, clipping the spatial range of the region;
path: string, the storage route of the image data after cutting.
Further, step S2 further includes:
S2.1, creating and managing a temporary file directory, creating a temporary file directory for each RECTANGLEDATA example, wherein the directory is used for storing temporary files of images, and cleaning after the image processing flow is finished;
S2.2, binding the form control data and updating an interface, wherein LISTRECTANGLEDATA list stores all rectangular partition data drawn by a user, each data item is an example of RECTANGLEDATA class, and the plug-in interface comprises a form control which is connected with LISTRECTANGLEDATA list through a data binding mechanism.
Wherein in this embodiment, S2.1 further comprises:
S2.1.1, temporary catalog generation: the system uses the Path class provided by the NET framework to generate a directory Path for the temporary file. By calling the Path.GetTempPath () method, the system is able to retrieve the path of the temporary folder assigned for the current user session. The system then uses the path.combine () method to combine the underlying temporary path with a unique identifier specific to the current operation (e.g., the ID of the cropped area) to create a private directory for storing temporary image files.
S2.1.2 temporary file use: when the clipping operation is completed, the generated raster data is exported to the temporary directory created as described above. Export operations rely on the raster data export function provided by ArcGIS to save IRaster objects as image files (typically in TIFF format). The path of the temporary file is stored in the path attribute corresponding to RECTANGLEDATA instances for use in subsequent steps (e.g., photoshop editing).
Life cycle of S2.1.3 temporary files: the created temporary file remains active throughout the image processing flow. Once the image is edited and saved in Photoshop and successfully reintroduced and embedded back into the ArcGIS project, the system will no longer need these temporary files. At this point, the system will perform a clean-up operation, deleting the temporary directory and its contents. This is typically accomplished by listening to the save event of Photoshop and, after confirming that the image has been successfully mosaic, calling the directory () method of the NET framework, deleting the entire directory and all related files to free up storage space and avoid data redundancy. The cleanup operation may be performed automatically when the user closes the ArcMap plug-in or ends the editing session, ensuring that no useless temporary files remain after the editing task is completed.
Step S2.2 further comprises:
s2.2.1 implement data binding: the data source attributes of the form control are set to LISTRECTANGLEDATA lists. When changes occur to the list, such as adding new rectangular partition data or updating the state of existing data, the form control automatically reflects these changes.
S2.2.2 user interface feedback: to enhance the user experience, form controls provide various visual feedback. For example, rectangular partitions of different states may display different color encodings, so that the user can clearly identify which partitions have been processed, which are processing, and which have not yet begun processing.
S2.2.3 interactive operations support: the user may interact with the rectangular partition data through the form control. For example, a user may select one or more partitions for editing, deleting, or viewing detailed information.
S2.2.4 real-time update mechanism: after the user edits and saves the temporary image data in Photoshop, the system captures this event and updates LISTRECTANGLEDATA the state of the corresponding partition in the list. The form control is updated accordingly, reflecting the latest state, such as changing from "editing" to "editing complete".
Further, step S3 further includes:
S3.1, refining the clipping flow, and executing the clipping flow by the plug-in through calling the API of the ArcGIS: defining clipping parameters, firstly determining clipping operation parameters including IRASTERLAYER interfaces of the selected images and IEnvelope limits drawn by a user; executing a clipping command, and extracting the intersecting part of the remote sensing image and IEnvelope by using the clipping function of the IRASTERLAYER interface to form a new IRaster object; the color depth and the wave band are set, so that the cut image can be correctly opened in Photoshop, the color depth is set to 8 bits and the wave band number is set to 3 during cutting, and the compatibility with Photoshop is ensured; determining a temporary file format, and selecting a Photoshop compatible image file format as a storage format of a cut image;
S3.2, generating and managing temporary files, generating a temporary path, and calling a Path. GetTempFileName () method by the plug-in to generate a temporary file path, wherein the path points to a temporary file directory defined by an operating system; saving the cut image, and utilizing the saving function of IRaster interface of ArcGIS to derive the cut image into the temporary file path generated in the last step, the name is CLIPRASTER _ "+UID of the cutting area; and updating RECTANGLEDATA information, and storing the generated temporary file path in the path attribute corresponding to the RECTANGLEDATA instance, so that the subsequent step reference is facilitated.
In S3.1, the clipping API in the example uses IExtractionOp interfaces, the optimal color depth value of the clipped 3-band raster data is 8-bit unsigned integer, and the clipping API in ArcGIS is "rstpixeltype.pt_uchar";
when the temporary image data is exported, a plurality of file formats can be selected, such as TIFF, JPEG, PNG, etc., so as to adapt to different editing and using scenes;
further, step S4 further includes:
S4.1, the Photoshop is called through a JavaScript script, and a corresponding temporary image file is opened for editing by a user;
S4.2, the file system monitor FILESYSTEMWATCHER tracks changes to the Photoshop file and captures edit save events.
Further, step S5 further includes:
S5.1, a state updating mechanism, when FILESYSTEMWATCHER detects a file change event stored by Photoshop, the system firstly verifies whether the change is matched with a temporary image file in tracking; after validation, the Status attribute of the corresponding RECTANGLEDATA object in update LISTRECTANGLEDATA is marked as "edited"; associating the status string parameters with the ID of RECTANGLEDATA objects to accurately identify and update the correct partition status;
S5.2, performing mosaic operation, wherein after all partition states to be edited are marked as edited, the system executes the mosaic operation, the mosaic operation is completed through a grid processing tool of an ArcGIS, and the corresponding region in the original remote sensing image is updated by using the image file saved after editing in the Photoshop; traversing LISTRECTANGLEDATA the list, calling a grid mosaic tool of the ArcGIS and a IMosaicRaster interface for each partition marked as 'PSsaved', and mosaicing and merging the edited image and the original image; the mosaic operation ensures that new image segments seamlessly blend into the original dataset, taking into account spatial alignment and pixel value matching.
Wherein, in this embodiment S5, in addition to using the file system monitor, the editing state can be monitored more directly by the API or script function of Photoshop to improve the reliability of the monitoring;
the end of the method may provide an automatic cleaning option for temporary files, allowing the user to choose to clean at a specific point in time or condition to better manage disk space.
The invention adopts an automatic image cutting and Photoshop editing flow, which obviously improves the efficiency and accuracy of the remote sensing image refining processing and reduces the time and labor required by manual cutting and editing.
Manual cropping and editing of a remote sensing image may take 30 minutes before automation is achieved, whereas after automation the entire process may take only 5 minutes.
The invention adopts real-time state monitoring and updating, enhances the transparency of the workflow, and enables the user to know the progress and state of image processing in real time.
In the previous workflow, the user may forget the progress of a certain task, so that reworking is caused, and the state update of each step can be seen through the interface in real time, so that the interactive design of the graphical interface conforming to production habit and the production practice are adopted, and the user without professional large-scale remote sensing software can easily perform the fine processing of the ultra-large remote sensing image.
After the scheme is used, a user can carry out professional and automatic ultra-large remote sensing image fine editing work by only installing ArcGIS software and Photoshop software.
