When you need to find the final assembly status of a piece of equipment or cabin, you need to search for photos in the corresponding folder according to the time node, and it often takes a lot of time to open each electronic image in the folder to check whether it is the object to be found
In addition, when the search object appears in multiple electronic images, the search method in the form of a folder is not conducive to switching back and forth between multiple electronic images

Embodiment Construction
[0017] In order to improve the query efficiency of satellite assembly electronic images and quickly and accurately find the query objects, the present invention proposes a digital integrated access method for satellite assembly electronic images based on satellite layout. The whole process is as follows figure 1 As shown, the main steps are as follows:
[0018] (1) The images of the satellite assembly process are obtained according to the layout of the satellite compartment and stored in two-level electronic image databases: the first image database is an image database stored in low-resolution and low-pixel form based on the original electronic images; the second image database is Raw image recording database;
[0019] When partitioning, try to ensure that the same device is in the same partition. At the same time, on the premise that the size of the partition ensures that the partition image acquired by the image acquisition device can clearly describe the current assembly s...

The present invention discloses a satellite integrated assembly image record query method. The method comprises the following steps of: (1), during a satellite integrated assembly process, dividing a satellite layout into partitions, then acquiring corresponding partition images according to the partitions, and storing the partition images in a first-level image database and a second-level image database, wherein the first-level image database is a thumbnail image database, the second-level image database is an original image database, and original image data are in one-to-one correspondence with thumbnail image data; (2), during image query, acquiring a partition where a user needs to search for an image record first and then according to the partition, calling all thumbnail images corresponding to the partition in the first-level image database; and (3), after the user locates a to-be-queried thumbnail image, according to a one-to-one correspondence relationship, acquiring a corresponding original image record from the second-level image database and providing the original image record to the user. According to the query method provided by the present invention, a grading and partitioning storage and query mode is adopted, so that the efficiency of querying a satellite integrated assembly image is effectively improved.
Description
technical field [0001] The invention relates to a method for recording and querying satellite assembly images. Background technique [0002] Satellite assembly is an important stage in the entire satellite development cycle. Since the electronic image can truly and accurately record the current state of the satellite, the shooting and preservation of the electronic image of the satellite assembly has become an important means to ensure the quality of the satellite assembly during the satellite production process and to strengthen the traceability of the product during the assembly stage. [0003] In the current method of storing and searching satellite assembly electronic images, the captured satellite assembly electronic images are named and saved according to the corresponding specifications, and a large number of final assembly electronic images in the same assembly stage are stored in the same folder. When it is necessary to find the final assembly status of a certain p...
