Embodiment
According to one of the utility model embodiment, the statistical system of the statistics object quantity that the utility model proposes is to obtain the height distribution plan according to the sensitive information of gained in a sensing range by computing, and whether certain objects, mobile object are arranged in the middle of judging according to this.In addition, in one embodiment more can be especially for calculate number quantity in sensing range, and relative subsequent control mechanism is provided accordingly.Yet, during practical application, above-mentioned object can be according to the requirements set object in sensing range, for example do not get rid of for people, animal, vehicle or special article be detected object.
According to embodiment, the embodiment schematic diagram of statistical system as shown in Figure 1A, this embodiment is that take humanoid is example, shown in Figure 1A, be that tip position (as ceiling) with the interior space is provided with a sensing apparatus 10, sensing apparatus 10 is from top to bottom launched detection signal (as transmitted wave 102) in a sensing range, and this detection signal also can adopt other invisible light, electric wave, sound wave etc. as detection signal.Because there are various visible objects in the interior space, as facility, article, people 101, the entity article such as 103 can reflect a reflected signal (i.e. the detection signal of reflection) to detection signal in the sensing range of sensing apparatus 10, for sensing apparatus 10, receive reflected signals.Background information based on having ground, existing facility to form in sensing range in addition, therefore the present embodiment can calculate the judgement prospect object height of (reflection interval is morning) according to transmitted wave 102 and the mistiming between relative reflection news signal, and then determine the depth of view information of each position in sensing range, show that according to this height of the visible object in this sensing range distributes.
In addition, one of the utility model embodiment can also distribute and judge whether according to this to have certain objects according to the height in this sensing range, suppose the object behaviour of judgement, can set height (as 100 centimeters high to 200 centimeters) and the shared area (as area of a circle diameter 50-70 centimetre of overlooking) of people of the judgement threshold behaviour of the object depth of field, threshold judges whether in scope to have one or more people (101,103) according to this.
Then, Figure 1B shows another embodiment schematic diagram of the statistical system of the utility model embodiment again.In this embodiment, being provided with sensing apparatus 10 ' equally above a sensing range, is to comprise with the video camera 11,12 in different directions, angle shot sensing range doing and illustrating at this sensing apparatus 10 '.Similarly, this sensing range comprises the background that original ground or facility form, by video camera 11,12 images of taking from different perspectives can be got rid of the object of original background, and then cause captured object to have different fog-levels because different f-numbers are arranged different video cameras, therefore can judge according to this depth of field.After getting rid of aforementioned background information, can distribute and judge foreground object according to the formed height of depth of view information smoothly.The people 101 ', 103 ' of embodiment like this, but during actual the realization, object is not got rid of other objects, as animal, vehicle etc., system can be set its judgement threshold according to the object of required detection, as the threshold setting content can be the parameters such as height, area occupied of aforementioned object.
Fig. 2 shows the height distribution plan schematic diagram of the statistical system making that utilizes the utility model embodiment, wherein be presented at a height interior level line of drawing according to aforementioned depth of view information of sensing range 20 (contour line), design according to demand the isocontour resolution that statistical system provides, each level line means a height value or an altitude range, a difference in height can be obtained between every two level lines, therefore the existence of certain objects can be judged whether according to isocontour density.
In this embodiment, wherein show two concentrated areas 201,203 that level line is comparatively intensive, according to depth of view information, can calculate this two concentrated areas 201,203 height and the information of occupied area, therefore according to threshold, judging is people, animal, vehicle or other objects.
For instance, take an adult as example, sensing apparatus is located at top, after the calculating of the depth of field, if 170 centimeters of people's height of heads, shoulder height are about 140 centimeters left and right, if, when the distance between 170 centimeters and 140 centimeters these two differences in height forms in the scope of about 60 centimeters diameters, can be judged as according to this adult.
According to previous embodiment, the utility model can utilize the information of the depth of field to judge the existence of object, more can judge according to the height changes in distribution of surrounding time the movement of this object, and can further calculate by specific turnover entrance or the number of particular range.
Refer to another embodiment schematic diagram of the statistical system that Figure 3 shows that the utility model embodiment.
In this embodiment, can for example above the interior space, be provided with sensing apparatus 30, in the scope of taking, there is a people 301 to advance when mobile, can distribute and judge this person 301 existence according to aforementioned height, and locking people's 301 position, and compare through the height distribution of surrounding time (in certain period), can be according to the variation judgement people's 301 who highly distributes movement.The above-mentioned technology according to image locking is for generally common, and, for the those skilled in the art can realize, at this, do not repeat.
Moreover, being provided with two threshold marks 31,32 in the scope detected in the wish of institute shown in Fig. 3, the object in can judging sensing apparatus 30 sensing ranges can also be followed the trail of the movement of object, and judge whether to cross over threshold mark 31,32 wherein existing.The gateway that can be used for a place embodiment illustrated in fig. 3 for example, can be for the judgement number of people entering in gateway by threshold mark 31,32 is set.
It is worth mentioning that, known technology utilizes the mode of image identification to carry out calculation according to each pixel, need powerful data-handling capacity, and the statistical system that the utility model embodiment discloses not adopts the known technology of utilizing the image identification judgement stream of people, and only according to the depth of field in specific sensing range with highly distribute to judge the stream of people, therefore the data of required processing are only general numerical analysis, required powerful of known technology not on system processing power; In other words, under same processing power, the utility model can be dealt with a large amount of object judgements, tracking and threshold judgement, and is applicable to large-scale place.
