Description

また、特許文献２には、店舗内の滞在者と移動者を区別して抽出することで混雑状況を把握する技術について開示されている。しかし、特許文献２においても、移動者と滞在者とを区別するだけでは、商品を見るために立ち止まっている人物とレジ待ちの人物を区別することができず、レジ待ち人数を計測することはできないという課題がある。また、特許文献２では、店舗内が混雑していて、移動者も非常にゆっくりとしか移動できない場合には、移動者と滞在者が区別できず、レジ待ち人数を把握することができないという課題がある。
以上のように、従来技術では、混雑している店舗内におけるレジ待ちの待ち行列のよう
に、待ち行列に並んでいないオブジェクトの動きが非常にゆっくりであったり、待ち行列が形成される位置が不定であったりするような場合に、待ち行列に並んでいるオブジェクトの数を計測できなかった。
本発明は、複数のオブジェクトにより形成された領域に含まれるオブジェクトの数をより精度よく計測することを目的とする。 Further, Patent Document 2 discloses a technique for grasping the congestion situation by distinguishing and extracting a resident and a moving person in a store. However, in Patent Document 2 as well, it is not possible to distinguish between a person who is stopped to see a product and a person who is waiting for cashiers only by distinguishing between a moving person and a resident, and it is impossible to measure the number of persons waiting for cashiers. There is a problem that you cannot do it. Further, in Patent Document 2, when the store is crowded and the moving person can move very slowly, the moving person and the staying person cannot be distinguished from each other, and the number of people waiting for cashier cannot be grasped. There is.
As described above, in the conventional technology, like a queue waiting for cashiers in a crowded store, the movement of objects not in the queue is very slow, or the position where the queue is formed is The number of objects in the queue could not be measured when it was undefined.
An object of the present invention is to more accurately measure the number of objects included in a region formed by a plurality of objects .

本発明によれば、複数のオブジェクトにより形成された領域に含まれるオブジェクトの数をより精度よく計測することができる。 According to the present invention, it is possible to more accurately measure the number of objects included in a region formed by a plurality of objects .

Claims

From the input image, specifying means for specifying the area formed by the plurality of objects ,
Measuring means for measuring the number of objects included in the area specified by the specifying means;
An information processing apparatus comprising:

An image captured by an image capturing device is further provided with an acquisition unit that acquires as the input image,
The information processing apparatus according to claim 1, wherein the specifying unit specifies a region formed by the plurality of objects from the input image acquired by the acquiring unit.

The identifying unit identifies a region formed by the plurality of objects from the input image by using a recognizer that recognizes a region formed by the plurality of objects from the input image. The information processing device according to item 1 or 2.

The specifying unit recognizes, for each pixel of the input image, whether or not the region formed by the plurality of objects is recognized, by recognizing whether or not the region is formed by the plurality of objects. The information processing apparatus according to claim 3, wherein a region formed by the plurality of objects is specified from the input image using a recognizer.

The specifying means uses the input image and the input image by using the recognizer learned in advance based on a learning image to which a category is assigned in pixel units and motion information of an object extracted from the learning image. The information processing apparatus according to claim 4, wherein a region formed by the plurality of objects is specified from the input image based on motion information of the object extracted from the input image.

6. The identifying unit identifies the region formed by the plurality of objects from the input image, using the recognizer that is Full Convolutional Networks (FCN). Information processing device.

The area formed by the plurality of objects specified by the specifying means is a queue area,
7. The measuring unit measures the number of objects included in the area of the queue identified by the identifying unit as the number of objects lined up in the queue. The information processing apparatus according to item 1.

Further comprising dividing means for dividing the area specified by the specifying means into individual queue areas,
The measuring unit measures the number of objects lined up in the queue for each region divided by the dividing unit, based on the region of the queue identified by the identifying unit. The information processing device according to claim 7 .

When the number of objects measured by the measuring unit is larger than a set threshold value, the output unit further outputs information indicating that the number of objects measured by the measuring unit is larger than the set threshold value. The information processing apparatus according to any one of claims 1 to 8, characterized in that.

From the input image, specifying means for specifying the area formed by the plurality of objects ,
Measuring means for measuring the number of objects included in the area specified by the specifying means;
