Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to according to detailed description of the invention provided by the invention, structure, feature and effect thereof, be described in detail as follows.
As shown in Figure 1-2, operate all kinds of health detection instruments and complete health detection, occur that until health detection instrument on-screen display (osd) area measurement parameter shows after numerical value, by image acquisition units, the whole on-screen display (osd) area of health detection instrument is carried out to video acquisition, ROI divides frame extraction unit to divide frame processing to the video data collecting, and extracting the ROI region of specifying, contrast processing unit transfers the conventional coordinates template data of all kinds of health detection instrument on-screen display (osd) areas of storing in central server and the ROI region of extraction compares, identifying processing.
Operate the complete health detection of all kinds of health detection instruments, occur that until health detection instrument on-screen display (osd) area measurement parameter shows after numerical value, by image acquisition units, the whole on-screen display (osd) area of health detection instrument is carried out to video acquisition, ROI divides frame extraction unit to divide frame processing to the video data collecting, and the ROI region of extraction appointment, contrast processing unit is transferred the conventional coordinates template data of all kinds of health detection instrument on-screen display (osd) areas and the ROI region of extraction of in central server, storing and is compared, identifying processing, to differentiate the kind of this health detection instrument, judge classification and the identification measured parameter value of measurement parameter, central server carries out storage administration to the measured parameter value of finally obtaining, and by display unit, measured parameter data is issued simultaneously
As shown in Figure 3, the conventional coordinates template of wherein said all kinds of health detection instrument on-screen display (osd) areas refers to, from the video that all kinds of health detection instrument display screen area are captured, extract a frame the most clearly on-screen display (osd) area is carried out to coordinate setting, determine four coordinate vertices A points, B point, C point and D point.ROI divides frame extraction unit to divide frame processing to the video data collecting, and the ROI region of extraction appointment, specified ROI region comprises 4 arrays apart from element (1,2,3,4) by one to be determined, these 4 represent respectively the distance of distance, selected areas frame right side bearing and whole picture left side bearing and the distance of selected areas frame lower sideline and whole picture upper sideline of distance, selected areas upper frame edge line and the whole picture upper sideline of selected areas frame left side bearing and whole picture left frame apart from element.Afterwards system by with the determined region of this array automatically to the picture of later collection compare, identifying processing.Differentiate the kind of the current health detection instrument that carries out video acquisition, the classification of judging measurement parameter and identification measured parameter value with this, central server carries out storage administration to the measured parameter value of finally obtaining, and by display unit, measured parameter data is issued simultaneously.
Due in crawl process the image that collects be difficult to identical with the ratio of health detection instrument display screen area, therefore system is differentiated by the proportionate relationship of selected ROI region and whole picture frontier distance, can not have influence on the accuracy of instrument identification and measurement data acquisition.
If the image collecting is not up to standard or unintelligible, system is None-identified all, and system is judged without this surveying record, need re-start video acquisition.
If system cannot be differentiated the kind of this health detection instrument contrasting, in identification processing procedure, system is judged without this surveying record, need re-start video acquisition.
If system cannot be judged the classification of measurement parameter contrasting, in identification processing procedure, system is judged without this surveying record, need re-start video acquisition.
If system is None-identified measured parameter value contrasting, in identification processing procedure, system is judged without this surveying record, need re-start video acquisition.
