BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art are briefly introduced below.

[0029] Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0030] Figure 1 It is a schematic diagram of an embodiment of the present application. DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0032] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0033] Example 1

[0034] like Figure 1 As shown, the construction site demolition follow-up method based on synthetic aperture radar interferometry technology described in this application includes the following steps:

[0035] The predetermined repetitive track path is generated according to the drawings of the construction site to be demolished. It is easy to understand that the predetermined repetitive track path is to make the site image generated by the same sensor or similar sensor in the parallel track twice imaging process more accurate.

[0036] In one embodiment, the predetermined repetitive track path is set as a single path extending continuously in a specified direction. The predetermined repetitive track path extends continuously from a specified starting position of the construction site to be demolished to a specified ending position of the construction site to be demolished.

[0037] It is easy to understand that during the ground imaging operation process, a more continuous and smooth on-site image can be obtained through a single continuously extended path, and the idle interval time of the imaging process can be reduced, which is conducive to improving the efficiency of imaging.

[0038] In another embodiment, the predetermined repetitive track path is configured as a plurality of paths extending unidirectionally along a specified direction. The plurality of predetermined repetitive track paths are arranged parallel to each other, and the plurality of predetermined repetitive track paths jointly cover the site to be demolished in a specified plane.

[0039] It is easy to understand that in the process of ground imaging operation, a more comprehensive on-site image can be obtained through multiple one-way extending paths, and the movement logic in the imaging process is simpler and more direct, which is conducive to reducing the occurrence of path errors in the presentation process.

[0040] An initial ground imaging operation is performed on the construction site to be demolished according to the generated predetermined repeated track path to generate an initial on-site image of the construction site to be demolished.

[0041] A secondary ground imaging operation is performed on the construction site to be demolished according to the generated predetermined repeated track path to generate a secondary on-site image of the construction site to be demolished.

[0042] The actual orbital path of the first ground imaging operation is compared with the actual orbital path of the second ground imaging operation to generate actual orbital path coincidence data. If the actual orbital path coincidence data is greater than a specified value, the subsequent steps are executed; if the actual orbital path coincidence data is less than the specified value, the ground imaging operation is re-executed.

[0043] It is easy to understand that after obtaining the first and second on-site images, it is necessary to confirm whether the on-site images can be directly synthesized, spliced ​​or compared. Calculating the actual orbital path overlap during the ground imaging operation is a more appropriate method. The specified value can be determined according to the actual progress requirements. For example, when the accuracy requirement is high, 90% can be selected.

[0044] According to the generated primary site image and secondary site image, image processing is performed on the primary site image and the secondary site image to generate elevation change information and deformation information of the site image. According to the generated elevation change information and deformation information, the completion amount, remaining amount and demolition progress of the construction site demolition are analyzed. According to the completion amount, remaining amount and demolition progress of the construction site demolition, the demolition progress of the construction site is adjusted.

[0048] A recording module is used to record an actual orbital path of a primary earth imaging operation and an actual orbital path of a secondary earth imaging operation.

[0049] A processing module is used to compare the actual track path of the initial ground imaging operation and the actual track path of the secondary ground imaging operation to generate actual track path coincidence data, perform image processing on the initial site image and the secondary site image to generate elevation change information and deformation information of the site image, and adjust the demolition progress of the construction site according to the generated elevation change information and deformation information analysis.

[0050] The preferred technical solution also includes a first guide mark and a second guide mark, wherein the first guide mark is used to mark a designated starting position of the construction site to be demolished, and the second guide mark is used to mark a designated ending position of the construction site to be demolished.
