Embodiment 1
[0042] see figure 1 , figure 1 It is a schematic structural diagram of a video image processing system of an anti-theft lock.
[0043] The receiving module 101 is configured to receive the target video collected by the camera.
[0044] The target video can be 5 seconds or 10 seconds. On the premise that the duration can be set according to the specific usage, it is necessary to ensure that the complete facial features belonging to the same person must be collected in the target video.
[0045] The processing module 102 is configured to decompose the target video according to the number of frames, and decompose the target video into a plurality of preliminary images.
[0046] The dynamic video is decomposed, and the decomposed static image is obtained, and the obtained static image is a preliminary image; it can be easily known that it is easier to compare the static image than the dynamic video, and the target The video is decomposed according to the number of frames, so th...
Embodiment 2
[0055] see figure 2 , figure 2 It is a schematic structural diagram of a receiving module in a video image processing system of an anti-theft lock.
[0056] The collection unit 1011 is used to collect a preliminary video captured by the camera.
[0057] When the collection unit 1011 receives the video recording instruction, it starts recording immediately.
[0058] The editing unit 1022 is configured to edit a video segment with facial features in the preliminary video, and mark the video segment as a target video.
[0059] If the collection unit 1011 receives the wrong video recording instruction, the formed video needs to be identified and analyzed by the editing unit 1022, and it is judged that there are facial features of no face; video; when there are still facial features of the face, it is intercepted, and the video segment is marked as the target video, and then the video segment of the non-target video is discarded.
[0060] The duration of the target video is 4...
Embodiment 3
[0062] An anti-theft lock video image processing system, further comprising
[0063] The adjustment module is used to collect the light intensity index; set the light intensity index; change the value of the preset value according to the light intensity index, when the light intensity index is greater than the light intensity index, reduce the value of the preset value, when the light intensity index is less than When the light intensity index is used, increase the value of the preset value.
[0064] Through the adjustment module, the size of the preset value can be changed, and then the available images that are more in line with the unlocking clarity requirements can be screened.

Abstract
The invention is applicable to the computer field, and provides a video imageprocessingsystem for an anti-theft lock, comprising: a receiving module for receiving the target video collected by the camera; and a processing module for processing the target video according to the number of frames decompose, and decompose the target video into a plurality of preliminary images; the identification module is used to analyze a plurality of the preliminary images and obtain the sharpness value; the extraction module is used to extract from the available database any At least one of the available images of facial features; a synthesis module, configured to integrate the extracted at least one of the available images to form a facial image with facial features and a sharpness value greater than the preset value; The synthesis module replaces one or two features that do not meet the unlocking requirements with features that meet the unlocking conditions on another preliminary image, so that all the facial features on the newly synthesized facial image meet the unlocking conditions, and the anti-theft lock is successfully opened.
Description
technical field [0001] The invention belongs to the field of computers, and in particular relates to a video image processing system for an anti-theft lock. Background technique [0002] With the continuous advancement of technology, more and more smart devices have entered people's daily life, and the most common one is the anti-theft lock with biometric function. [0003] Biometrics refers to fingerprint recognition and face recognition, but in the process of using face recognition, the face is not fixed, which requires video processing of the face for a period of time, but the current face recognition When the anti-theft lock performs the above processing, it needs to select an image that meets the definition threshold in a video, and then use the image to compare with the image in the database. It will waste a long time to select the image with the five senses that meet the definition. , and even sometimes need to re-record. SUMMARY OF THE INVENTION [0004] The embo...
