Definitions
- the invention relates to a method for monitoring the accumulation of persons according to the preamble of claim 1.
- a sensor module detects the location coordinates of individual persons in a room to be monitored from entering to leaving.
- a sensor module can serve a CCD camera.
- means and methods or algorithms of the image processing are used to detect or identify the objects and subjects located in a room. From gray or color values and circumscribing shapes, the movement behavior of persons is derived according to position and speed.
- a disadvantage of this prior art is that thereby no recognition of dangerous incidents or potentially developing dangerous situations is possible.
- the monitoring area can not open to the imaging device, concealed subregions, de ⁇ ren additions are in the monitored area, and a review of the hidden sub-regions can based on comparison ⁇ patterns for the inflow and outflow through the entrances SUC ⁇ gen.
- the comparison patterns for the subregions are dependent on the weather, the season, the time of day, the day of the week and / or the type of event.
- a model for the behavior of the persons in the subregions is created for the evaluation, in which the subareas are assigned parameters depending on the weather, the season, the time of day, the day of the week and / or the type of event.
- a better prognosis can be made for typical situations depending on circumstances such as time or weather.
- the assessment will be more accurate in the event that many people leave a folk festival in the late evening in bad weather.
- An accident can be detected by a comparison pattern in which the speed of individual persons within ei ⁇ nes flow of people is significantly lower and these move to a center and / or a circle without other people trained around this.
- a panic situation is detected by a comparison pattern in which flows of people with high speed of movement, high density of people occur at the same time forming areas without or with a few people.
- the gradient of the person density is evaluated.
- the first and second Ablei ⁇ tion of the person density and / or the speed of movement of the people is evaluated.
- the number of people in an area or subarea is a function of time and place. By comparing the positions of the persons at different times, the derivative of this function is determined by time or approximated by difference quotients.
- the derivation according to the location (gradient) provides information about the local changes in the number of persons or persons (number of people / area). Even higher derivatives can be approximated by differential quotients.
- the number of persons and the flows of persons can be predicted.
- An evaluation is possible even if not all persons can be recorded. It is also possible to additionally include selected persons in order to obtain information about the distribution of certain groups of persons in the mass of persons. hold. This can be, for example, children or wheelchair users, who need a higher level of protection than other people. Such persons may be recognized by special markings such as a cap or cap, or physical characteristics such as height.
- FIG. 1 is a schematic plan view of a monitoring area with subregions on the basis of the example of a Murphy ,
- FIG. 2 schematically shows an assignment of parameters to subregions
- Fig. 3B schematically shows a second comparison pattern for an accident
- FIGS. 4A-4C schematically show the sequence of a comparison pattern for a panic situation.
- FIG. 1 shows schematically in plan view a monitoring range 1 with subregions on the basis of the example of a popular event .
- the persons are indicated by dots.
- the gradient of the streams of people outside in the sub-area entrance beer tent 5 can be used as a guideline for determining the number of persons in the subarea beer tent 4.
- the monitoring of the movement pattern allows an estimation of a development in a subsequent period.
- FIG. 2 schematically shows an assignment of parameters to subregions.
- the driving business 3 the beer tent 4, a roast chicken stand 9 and a Rie ⁇ senrad 10 are arranged.
- typical properties are taken into account in the comparative samples.
- Under section z as in areas that have normally gleichze ⁇ FLOWING persons distribution as the road section 2, only sparse with people under areas such as the roller coaster as
- a concrete assessment and prognosis is described ⁇ model to allow for different scenarios, a Prog ⁇ nose of the distribution of people in sub-regions, starting from the current distribution people.
- different parameters eg P (weather) and P (time), which are dependent on the respective sub-area and correspond to an "attractiveness" for persons under the parameter condition Scenarios and for the sub-area concerned.
- the value range of the parameters is specified as [0,1].
- FIG. 2 shows by way of example a parameterization with values P A for a-bends and at the same time P R for rain.
- Fig. 3A schematically shows a comparative pattern for an accident.
- the parties are shown as a point with an arrow on its movement direction and a movement speed ent ⁇ speaking arrow length.
- Fig. 3B schematically shows a second comparison pattern for a possible accident. Around a few people, a circle without further people forms and the speed of the people in this circle is very low or zero.
- FIGS. 4A-4C schematically show the timing of a comparison pattern for a panic situation.
- critical masses, traps and accident patterns can either be recognized directly or predicted via extrapolation, eg a linear extrapolation of the movements. This can be used to respond appropriately, such as automatically triggering alerts, informing and enabling security services.
- the monitoring can automatically focuses on the danger zone, where refined ⁇ to.
- the threshold values are specified depending on which parameters (weather, time of day, etc.) are available.
- the threshold values can be determined depending on a sub-range. For example, in a subway station at rush hour, higher person densities are tolerable than at 3 o'clock in the morning, when an accumulation of people may indicate a danger situation, such as a developing brawl.
- the method according to the invention represents a control loop, ie the information obtained can be used directly for better detection in the next steps. When a crisis area detected automatically, for example by a threshold value, so in this region, the detection can be verfei ⁇ nert. Options include zooming in or special alignment of additional cameras. Next, additional data can be determined as to the density of the BEWE ⁇ transfer speed of persons as well as the uniformity and distribution of the speed of movement.
- the reference patterns e.g. based on experience in the past, and the parameters are adjusted. Possible measures may be to block inputs and to only use them as an output, as well as further monitoring based on comparison patterns and parameters for the case of evacuation.
