Specific embodiment
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in combination with Examples.It should be noted that not conflictingIn the case of, the features in the embodiments and the embodiments of the present application can be combined with each other.
For the monitoring of the cross contamination of existing food-processing industry, the key link usually intersected according to food,The system on hilllock must not be altered by working out operator.Personnel are divided according to the difference of work area clean degree, specify cleannesPersonnel can only must not alter hilllock in specified regional work.If occurring altering hilllock behavior, personnel can only be from high cleaning region to low cleaningRegion.The execution of system, by artificial regular visit, alters hilllock to personnel mainly by the mode for manually checking and supervising mutuallyThe behavior of cross contamination is caused to exercise supervision.
But it is this fully rely on artificial test mode, the subjective judgement and working attitude of heavy dependence inspection personnel,The job specification of regular visit makes it easily becomes the routine public affairs for becoming a mere formality, performing practically no function as one as time goes byThing, supervision, check it is ineffective.
On the other hand, if food processing place area is larger, environment is complicated, personnel are more, if when manual inspectionIt is difficult to distinguish the lustration class of each personnel, so as to cause low efficiency is checked.Inspection personnel can only have according to hilllock behavior judgement is alteredThe accidentally risk of cross contamination, can not accurately analyze the height of different zones food cross contamination risk.
For food cross contamination high risk zone can not be judged, artificial supervisor alters that hilllock speed is slow, efficiencyThe problem of low, heavy workload, in an embodiment of the present invention, in conjunction with digital video technology, the high wind of intelligent decision cross contaminationDanger zone domain, and identify that personnel alter hilllock behavior.
For this purpose, providing a kind of cross contamination in the present embodiment determines method, Fig. 1 is side according to an embodiment of the present inventionMethod flow chart, as shown in Figure 1, the process includes the following steps:
Step S102 acquires the monitor video in different lustration class regions；
Step S104 draws the activity trajectory of the different affiliated personnel in lustration class region according to the monitor video；
Step S106 determines the cross contamination situation in different lustration class regions according to the activity trajectory.
Before the step S102 of the present embodiment, this method can also include: to different lustration class area informations andThe information of the different affiliated personnel in lustration class region carries out typing.
In the step S104 of the present embodiment, the different affiliated personnel in lustration class region can be identified, and drawn notWith the activity trajectory of the affiliated personnel in lustration class region.
In the step S106 of the present embodiment, low lustration class region can be judged whether there is according to the activity trajectory and is belonged toPersonnel enter high-cleanness hierarchical region；If it is, determining that there are cross contamination risks, and high-cleanness hierarchical region will be enteredThe low lustration class region belongs to personal information and reports.
In the step S106 of the present embodiment, low lustration class region can also be belonged to personnel and enter high-cleanness grade areaThe crosspoint of the activity trajectory of the activity trajectory and affiliated personnel of high-cleanness hierarchical region in domain is set as cross contamination risk point；RootIt is determined according to the frequency that track cross occur in the stay time and cross contamination risk point of described each track of cross contamination risk pointIntersect risk class.
In the present embodiment, different colours or label can be used to mark the activity that different lustration class regions belong to personnelTrack.
For the ease of the understanding to technical solution of the present invention, retouched in detail below by the embodiment of a concrete applicationIt states.
It is true to propose a kind of cross contamination for the monitoring situation of the cross contamination risk in food processing region for the present embodimentDetermine method.As shown in Fig. 2, mainly including the following steps:
Step S202, the monitored picture of the camera of acquisition different food products operating space deployment.
The identification feature information (for example, facial characteristics) of each operating area employee of typing food and affiliated in systems in advanceWorking region lustration class information, and different colours calibration is carried out to each operating area by lustration class requirement.In the present embodimentIn, each operating area is broadly divided into area according to lustration class: contaminated area (e.g., garbage disposal area, food materials destroy area etc.) labelFor red；General clean area (such as: cut distribution area, roughing area, table-ware disinfection area) is demarcated as blue；High-cleanness region is (such asCold food area eats area, decorative cakes area etc. raw) it is demarcated as green.
The color of calibration can be used for drawing personnel activity track.Wherein, lustration class is higher, and corresponding permission is higher,I.e. high-cleanness area people has the permission into low clean area, and low clean area personnel must not enter high-cleanness region.
Video acquisition is carried out according to camera in different food products operating space, and clean according to the operating space that camera is located atGrade is spent, the employee's color that may occur in which in picture area is limited.
Step S204, intelligent recognition difference lustration class area belong to personnel in the activity trajectory of each operating area of food.
The monitored picture acquired by camera, it is clean belonging to identification personnel to personnel's progress human face analysis in pictureThe colouring information in net grade area, draws out the activity trajectory of designated person, and according to each residence time length track draftingResidence time thermodynamic chart on line.Personnel track for not being prestored into system carries out abnormal track calibration.
Step S206, analysis low-risk operating area personnel enter high risk operating area situation, and according to different cleaningsGrade personnel's track cross situation marks cross contamination high risk zone.
The track color according to as defined in picture identifies whether the personnel track color occurred in real time is consistent, if unanimously, sentencingFixed track is normal；If it is inconsistent, and whether the track color permission is lower than in designated color, then determines that the personnel alter hilllock in violation of rules and regulations,Hilllock personal information will be altered and send regulator end.
Also the point of different colours track cross can be demarcated in monitored picture according to the track of different colours, which isCross contamination risk point.It is determined and is handed over according to the frequency that track cross occur in the stay time of each of crosspoint track and crosspointPitch risk class.Residence time is longer, risk is higher；The intersection frequency is more, and risk is higher.
In the above embodiment of the invention, according to the motion track crossing instances intellectual analysis of different clean area personnelCross contamination region, the workload for improving the accuracy of cross contamination region decision, reducing original manual inspection, and can rootCross contamination analytical grade is analyzed according to number of crossings and stay time, improves regulator to management region Food Safety AnalysisGrasping level.
