Embodiment 1
[0047] Such as figure 1 As shown, the present embodiment provides a secondary research and judgment method for portrait early warning information, including:
[0048] Step 1. According to the obtained early warning data, if the early warning data is the analysis result of a portrait analysis system, go to step 2; otherwise, go to step 3;
[0049] Step 2. According to the early warning data, if the acquaintance value in the early warning data is greater than the first set threshold, then send the early warning data; if not,
[0050] Then use other portrait analysis systems to analyze the surveillance photos and passers-by photos in the early warning data, if the degree of acquaintance obtained is greater than the second set threshold, then send the early warning data; otherwise, do not send the early warning data; then end the steps;
[0051] Step 3. According to the early warning data, if the acquaintance value in the early warning data is greater than the first set threshold...
Embodiment 2
[0057] Such as figure 2 As shown, in this embodiment, a kind of secondary research and judgment device for portrait early warning information is provided, including:
[0058] Judging the analysis system module, according to the obtained early warning data, if the early warning data is the analysis result of a portrait analysis system, enter the single analysis system early warning module; otherwise, enter the multi analysis system early warning module;
[0059] The early warning module of the single analysis system, according to the early warning data, if the acquaintance value in the early warning data is greater than the first set threshold, then send the early warning data; if not,
[0060] Then use other portrait analysis systems to analyze the surveillance photos and passers-by photos in the early warning data, if the degree of acquaintance obtained is greater than the second set threshold, then send the early warning data; otherwise, do not send the early warning data; ...

Abstract
The invention provides a secondary study and judgment method and device for portrait early warning information, and the method comprises the steps: transmitting early warning data when a similarity value in the early warning data is greater than a first set threshold value and is an analysis result of a portrait analysis system; when a similarity value in the early warning data is greater than a first set threshold and is an analysis result of at least two personal image analysis systems, comparing a passerby photo in the early warning data with a permanent resident identity photo set library, analyzing a comparison result, and judging whether personnel information with a higher similarity value exists or not; if the personnel information with the higher similarity value does not exist, early warning data are sent; if not, not sending the early warning data; if the similarity value in the early warning data is less than or equal to a first set threshold value, analyzing the surveillance photo and the passerby photo in the early warning data by adopting an other person image analysissystem, and if the obtained similarity value is greater than a second set threshold value, sending the early warning data; if not, not sending the early warning data; and the accuracy is improved.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for secondary research and judgment of early warning information of portraits. Background technique [0002] With the development of portrait technology, it is used more and more widely, and early warning has become an important means for the police to handle cases. Many of the early warning data are misreported data, which seriously affects the efficiency of police handling cases and leads to a large waste of human resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and device for secondary research and judgment on portrait early warning information, so as to improve the accuracy of research and judgment and reduce the waste of human resources. [0004] In the first aspect, the present invention provides a secondary research and judgment method for portrait early warning informa...
