Problems solved by technology

[0003] At present, the embedded device imports the face base map by uploading the picture to the device, and then analyzing the picture through an algorithm to find out the total number of faces in the picture. When the total number of faces analyzed is 1 When modeling, and then import the next picture after modeling, this method makes the import speed of the face base map slow, which seriously affects the performance of embedded devices

Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] Such as Figure 1 to Figure 4 As shown, an optimization method for quickly importing a face target library, including steps:

[0034] S1. Start the basemap batch adding task on the UI interface;

[0035] S2. Start the background import thread;

[0036] S3. Open the directory traversal file;

[0037] S4. Record the total number of files, and set up abnormal file records under the U disk directory; set up a temporary cache directory under the hard disk mode;

[0038] S5. obtain the file names in turn, and read the files to the memory;

[0039] S6. Determine the file type in turn, obtain the file size, and record it into the warehouse;

[0040] S7. After the file traversal is completed or when the number of base maps reaches the set value, close the directory;

[0041] S8. End the background import thread.

[0042] During the process of adding b...

Abstract

The invention provides an optimization method for quickly importing a face target library. The optimization method comprises the following steps: starting a base map batch adding task on a UI interface; starting a background import thread; opening a directory traversal file; recording the total number of files, and establishing an abnormal file record under a U disk directory; establishing a temporary cache directory in a hard disk mode; sequentially acquiring file names, and reading files into a memory; sequentially judging file types, obtaining file sizes, and recording and storing the files; closing the directory after the file traversal is completed or when the number of the base maps reaches a set value; stopping the background import thread. The method has the beneficial effects thatan original single-thread mode is changed on the basis of a base map import mode, previous operations of starting import, algorithm analysis, modeling and repeating are changed into batch import andalgorithm analysis after import is completed, the import mode does not influence other operations, and meanwhile, base map import is more efficient.

Description

technical field [0001] The invention relates to the technical field of face recognition for embedded devices, in particular to an optimization method for quickly importing a face target library. Background technique [0002] As the most intuitive identification method in biometric identification technology, face recognition has the irreplaceable advantages of other biometric identification technologies, such as user-friendly, concealed operation, easy to use, accurate positioning, economic benefits and good system scalability. [0003] At present, the embedded device imports the face base map by uploading the picture to the device, and then analyzing the picture through an algorithm to find out the total number of faces in the picture. When the total number of faces analyzed is 1 When modeling, import the next picture after modeling. This method slows down the import of the face base map and seriously affects the performance of the embedded device. Contents of the inventio...
