1. FIG. 1 is a block diagram showing the functional configuration of the monitoring device 100 according to the first embodiment. The monitoring device 100 includes an imaging unit 20, an image processing unit 30, and a display processing unit 40, and acquires attribute information of passers-by. The passerby attribute information acquired by the monitoring device 100 is provided for commercial use, statistical use, and use for guiding a passerby, for example. Each block in the monitoring device 100 can be realized by an electronic element such as a CPU of a computer, a mechanical part, or the like in terms of hardware, and a computer program or the like in terms of software. It depicts the functional blocks realized by. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by combining hardware and software.

The imaging unit 20 is, for example, a CMOS, CCD, or TOF (Time Of Flight) type camera for visible light imaging or an infrared camera, and photographs an area to be monitored (hereinafter referred to as a “monitoring area”). The monitoring area is, for example, an entrance/exit or passage of a building, and the imaging unit 20 is provided near the entrance/exit or passage of the building. The imaging unit 20 acquires an image of a passerby including the background in real time.

The image processing unit 30 has a passer-by determination unit 31 and an attribute information acquisition unit 32. The passer-by determination unit 31 determines a passer-by in the surveillance area by an image recognition method based on the image captured by the imaging unit 20, and calculates the position of the passer-by in the image. The passer-by determination unit 31 can use a known image analysis technique. The passer-by determination unit 31 specifies a passer-by, for example, by comparing the graphic data corresponding to the contour of the person stored in the storage unit (not shown) with the shape existing in the image captured by the imaging unit 20. To do. When a plurality of passers-by exist in the image, the passer-by determination unit 31 determines each passer-by and calculates the position in the image.

The attribute information acquisition unit 32 further performs detailed image recognition on the passers-by discriminated by the passer-by determination unit 31 to obtain passer-by attribute information. The passerby attribute information is classified into, for example, physical attributes, attributes relating to a group that connects a plurality of passers, attributes relating to belongings of passers, attributes relating to actions of passers, and the like. Physical attributes include, for example, gender, age, height, physique, body type, body width, child, adult, pregnant woman, physical handicap, gait, complexion, makeup, eye color and hair Color etc. Each attribute is estimated by collating the figure data of the characteristic part of the person used for discrimination of each attribute with the shape existing in the image captured by the imaging unit 20. For example, the gender attribute is estimated using artificial intelligence that has been learned in advance for men and women of multiple nationalities. The attributes of age are estimated by determining skin tone, walking style, wrinkles on the face, and the like. For the height, the position of the head (upper end) and the position of the foot (lower end) of the passerby in the image picked up by the image pickup unit 20 are obtained, and the image pickup unit 20 and the passerby are obtained in accordance with the known installation height of the image pickup unit 20. The distance between them can be calculated, and can be obtained by the upper and lower ends on the image. Further, the distinction between an adult and a child is estimated based on the height and the distance (step) that the person advances in one step. The physical handicap presence/absence attribute is estimated by the presence/absence of a cane, a crutch, a wheelchair, or the like. In addition, it is estimated by the state of being dragged. Furthermore, various states of passersby can be estimated based on the gait. For example, pregnant women often have a tendency to have a short stride, a large hip abduction angle, and a small spinal rotation angle. Estimate if there is.

Attributes relating to groups that connect a plurality of passers-by are, for example, couples, families, infants, student groups and travel groups. The attribute information acquisition unit 32 derives an attribute as a group that connects the plurality of passers, based on the attributes of the plurality of passers.

Attributes of the belongings of passers-by include, for example, clothes, shoes, glasses, hats, umbrellas, pets, strollers, and carts. It is assumed that these items are incidentally image-recognized by the passer-by discriminator 31 with respect to an article moving together with the passerby and are associated with the passerby. In addition, by using a walking aid, a wheelchair, or the like, it is possible to determine the state of the passerby based on the belongings (for example, the presence or absence of a handicap or an injury).

The attributes relating to the motion of the passerby include, for example, the direction of the face and the line of sight, the facial expression, the incidental motion, the vocalization state, and the voice quality (the pitch of the voice). The incidental operation is, for example, so-called “walking while walking” such as watching the mobile terminal, operating the mobile terminal, listening to music, and the like.

The attribute information acquisition unit 32 may acquire secondary attribute information by combining a plurality of primary attribute information acquired by image recognition. The attribute regarding the consumption preference of the passerby may be acquired based on the attribute regarding gender and the attribute regarding clothing. Further, the attributes relating to the physical condition, health, mental state, etc. may be acquired based on the attribute information relating to the complexion color and the skin color and the attribute information relating to the facial expression. The primary attribute information acquired by image recognition and the secondary attribute information acquired by combining a plurality of primary attribute information are not limited to those exemplified here.

The display processing unit 40 has a symbol generation unit 41, an image generation unit 42, a display unit 43, a storage unit 44, and the like. The symbol generation unit 41 generates a symbol image indicating a passerby according to the attribute information acquired by the attribute information acquisition unit 32. For example, the symbol image is generated according to the gender which is the attribute information. Also, the size and color of the symbol image may be changed based on the age, adult, and child attribute information.

Further, the symbol generation unit 41 may generate the symbol image such that various attribute information is written in a balloon that pops up when the cursor is placed on the symbol image included in the display screen described later. The balloon that pops up in this way is also considered to be part of the symbol image.

The image generation unit 42 generates a display image in which the symbol image generated by the symbol generation unit 41 is combined with the current image or the still image of the monitoring area acquired in advance. In the display image, the image of the actual passerby is replaced with the symbol image. The image generation unit 42 may use the position in the image of each passerby calculated by the passerby determination unit 31 when combining the symbol images.

The display unit 43 is a device such as a liquid crystal monitor for displaying an image, and displays the display image generated by the image generating unit 42. The storage unit 44 is configured by a storage medium such as a RAM, a hard disk, or an SD card, and stores the display images generated by the image generation unit 42 in time series.
