Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a living environment data collection system for collecting data for optimizing the size of a house and house equipment.
[0002]
[Prior art]
Even if a healthy person does not have a slight difference in level or height, the elderly person or a disabled person feels inaccessible or difficult to use.
[0003]
However, the degree of physical function of the elderly and the disabled varies widely and varies greatly from person to person, so it is difficult to size housing and housing equipment for such people. However, optimizing the size of the housing and housing equipment that suits the person is very important in order to live comfortably and safely.
[0004]
For this reason, data collection for determining the size is performed at universities or manufacturers' research institutions.
[0005]
However, the number of samples is important for improving the reliability of the collected data, and it was necessary to gather a large number of people to obtain the necessary samples.
[0006]
[Problems to be solved by the invention]
However, as described above, there is a problem that it is expensive and limited to gather a large number of people only for data collection.
[0007]
Furthermore, since the number of people gathered cannot be random, there is a problem that the sampling personnel tend to be averaged (statistically correlated).
[0008]
Accordingly, an object of the present invention is to enable sampling of a large number of data without cost and to obtain data of an unspecified number of people.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, body size measuring means comprising a camera for photographing a subject, and processing means for calculating the size of each part of the subject's body from image data photographed by the camera, And a simulator device that can adjust the height, width, mounting position, and passage width of housing facilities based on the measurement data of the body size measuring means, and a simulator device that is adjusted based on the measurement data Second measuring means for measuring the dimensions of each part of the test subject and the simulator device based on image data obtained by photographing the state in use with the camera and the measurement data of the body size measuring means And a database that stores the measurement data of the second measuring means.
[0010]
By adopting such a configuration, the subject is photographed by the camera of the body size measuring means, and the processing means calculates the size of each part of the subject's body from the photographed image data. By using the camera in this way, it is possible to easily measure the size of the elderly and the disabled.
[0011]
Moreover, if the height, width, mounting position, and passage width of the simulator device are adjusted according to the calculated size of each part of the subject with the data calculated by the body size measuring means, the simulator device is immediately used for the subject. Can be made. Also, the state can be taken with the camera of the second measuring means, and the size of each part of the test subject and the simulator can be calculated from the taken image data, so if those data are stored in the database, A large amount of data can be collected in a short time.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
As shown in FIG. 1, this living environment data collection system includes a body size check zone 1a provided with a body size measuring means, a daily life movement ability (ADL) shim space provided with various simulator devices and a second measuring means. 2a and an office space 3a provided with a database host computer.
[0014]
In addition, as shown in FIG. 2, the devices provided in the body size check zone 1a, shim space 2a, and office space 3a are connected via a LAN so that data can be shared.
[0015]
The body size check zone 1a is provided with the body size measuring means 1, and is a zone for measuring the dimensions and motion areas of each part of the body.
[0016]
As shown in FIG. 3, the body size measuring means 1 includes a video camera (or a digital still camera) 10, a monitor 11, and a processing computer 12. The processing computer 12 includes a video capture board 13. ing.
[0017]
The video capture board 13 allows the processing computer 12 to capture the video signal from the video camera 10 and display the video signal on the monitor 11, and one frame of an image taken by the video camera 10 in response to a command from the processing computer 12. Each captured frame image is captured by the processing computer 12 so that it can be displayed as a still image.
[0018]
Further, the processing computer 12 includes a program for counting the number of pixels in the designated area in the displayed still image. As shown in FIG. 4, the operator can use a pen or a mouse while viewing the still image on the monitor. If the measurement area is designated by moving the cursors C1 to C4, the number of pixels in the designated area is counted.
[0019]
By counting the number of pixels in this way, the body size measuring means 1 can measure the size of each part of the subject in a non-contact manner, and the principle will be described in detail below.
[0020]
That is, for example, when the maximum display range of the monitor is 1024 × 768 pixels, as shown in FIG. 4, the area for projecting the subject is set to be 640 × 480 pixels, and the subject and the camera are within this range. Determine the relative position. Here, as shown in FIG. 5, for example, the distance A between the camera and the subject is 4700 mm, the height B where the camera 10 is installed is 1250 mm, the measurement range E (vertical and horizontal common) is 2500 mm, and the subject angle D is 15 °. It was.
[0021]
Then, the horizontal range projected on the screen is 2500 mm, and the size per pixel (2500 ÷ 480) is 5.208 mm, so the minimum resolution is about 5 mm.
[0022]
Therefore, for example, as shown in FIG. 4, if an area is designated, the length of that part can be achieved by counting the number of pixels in the designated area.
[0023]
Here, the error factor of this measurement method is considered.
[0024]
For example, when the person in FIG. 5 has a height of 1700 mm, the point A that is the normal position (from 4700 mm in this case) and the error when standing 1 cm inside from that position are calculated,
First of all, considering below the center line o,
Regular coverage angle = tan ^-1 (1250/4700)
= 14.893 °
When standing 1cm inside
Field angle = tan ^-1 (1250/4690)
= 14.923 °
Therefore, the amount of change is
X = 4700 tan (14.923 °) -4700 tan (14.893 °)
= 2.5mm
Next, consider above the center line o.
[0025]
Regular coverage angle = tan ^-1 (450/4700)
= 5.469 °
When standing 1cm inside
Field angle = tan ^-1 (450/4690)
= 5.481 °
When standing 1cm inside
Field angle = tan ^-1 (1250/4690)
Therefore, the amount of change is
X = 4700 tan (5.481 °) -4700 tan (5.461 °)
= 1.66 mm
From this, it can be confirmed that an error of about 4.16 mm occurs in the vertical direction. For this reason, if the position of the subject is fixed, the measurement accuracy can be improved.
[0026]
Daily Living Ability (ADL) Shim Space 2a is a space equipped with a simulator device. It consists of the entrance, living room / bedroom and toilet, laundry, bath, housework room, washroom, kitchen, etc. The floor plan is similar.
[0027]
Moreover, the simulator apparatus provided there is comprised by the following things which can change the height of a house or housing equipment, a width, an attachment position, and a passage width, for example.

In addition, a simulator device that can change the arrangement of outlets and switches is also provided, which will be described later.
[0029]
Further, these simulator devices are provided with second measuring means 3 using a video camera 10 '.
[0030]
As in the case of FIG. 3, the second measuring means 3 connects a video camera (or a digital still camera) 10 ′ and a processing computer 12 ′ provided with a capture board, and the processing computer 12 ′. Measurement can be performed while looking at the monitor 11 'connected to. The simulator device and the processing computer 12 'are connected via an interface so that the simulator device can be adjusted.
[0031]
Therefore, the second measuring means 3 displays the image captured by the camera 10 ′ on the monitor 11 ′, and changes the size of the displayed image in units of pixels based on the data measured by the body size measuring means 1. The size of the simulator device can be changed by moving the simulator device so that the captured image matches the display image whose size has been changed.
[0032]
This will be described using, for example, a housework table lifting system shown in FIG.
[0033]
As shown in FIG. 6, the housework table elevating system comprises the slides 20 on both sides of the table top, and the slide 20 is moved by a motor 23 via a ball screw (not shown) and a transmission gear 21. It is designed to move.
[0034]
The measurement method is performed in units of pixels as described above. As shown in FIG. 7, the table image captured by the camera 10 ′ is displayed on the monitor 11 ′ as shown in FIG. Here, as shown in FIG. 8, the number of pixels in the range pix designated by the cursors C5 and C6 is counted. At this time, as described above, since it is necessary to determine the scale of the range to be detected in the image based on the distance, the camera 10 ′, the center of the table, and the center o ′ of the monitor 11 ′ become the same reference. Camera 10 'is installed. In this way, the camera 10 'causes the display image and the capture image to be in a one-to-one proportion.
[0035]
Therefore, the displayed image is resized in units of pixels. Further, the display image and the captured image whose size has been changed are overlapped on the monitor 11 ′ as shown in FIGS. 9A and 9B, and the table is moved up and down so as to coincide with the changed display screen. The height can be adjusted. Then, the size is changed on the monitor 11 'and the data is also saved. At that time, the size of each part of the subject in use can be measured by allowing the subject to use the adjusted table and capturing the state. At this time, as shown in FIG. 6, if the subject is rotated by the turntable 23 together with the table and captured by the camera 10 ′, the size of each part can be measured without moving the subject or the camera. For this reason, it is possible to accurately measure the size of details without giving a burden to an elderly person or a person with a physical disability.
[0036]
The measured data is sent to a host computer connected via a LAN and stored in a database.
[0037]
At the same time, the captured image used for measurement can be saved as an image file, and the saved image file can be recalled for examination.
[0038]
As described above, the host computer 4 arranged in the office space includes a database of data received from each computer for receiving and measuring, analysis data, correction data, and image data.
[0039]
This embodiment is configured as described above. Next, a data collection method will be described by explaining a measurement procedure.
[0040]
In this collection system, the subject registers at the reception of the exhibition facility, measures each size of the body in the body size check zone 1a, and uses a simulator device in the shim space 2a adjusted on the basis of the measured size. When you experience the convenience of housing equipment, the data is collected.
[0041]
That is, when the subject registers with the reception computer, the subject is transferred to the host computer 4 as shown in FIG. 10, and a file for the subject is generated in the database. When other simple personal data such as name, age, sex, presence / absence or degree of disability is registered in the generated file, a code number is given, and subsequent data is managed by this code number.
[0042]
When the acceptance is completed, the body moves to the body size check zone 1a and measures the body size and the motion area.
[0043]
In this measurement, the subject is placed at a predetermined position in the zone as described above, and is photographed with a camera. At that time, as shown in FIG. 11, a predetermined pose is taken and the operation area is also measured. Such a pose is used when adjusting various simulator devices of the shim space 2a to be experienced after the measurement, and unnecessary ones may not be measured depending on the type of the simulator device to be experienced.
[0044]
The measured data is transferred to the host computer for processing as shown in FIG.
[0045]
When the measurement is completed, the process proceeds to the shim space 2a. In the shim space 2a of this form, first, the user can experience the size of the entrance and the height of the bench at the entrance corner of FIG.
[0046]
That is, in this corner, the personal code of the subject is input to the terminal, and the width of the entrance space is adjusted by moving the entrance wall according to the average size displayed on the terminal as shown in FIG.
[0047]
Here, the average dimension displayed on the terminal is an average dimension prepared in the database based on the size of the subject, and is corrected based on the collected data.
[0048]
On the other hand, the subject determines the position of the vest while re-adjusting until it is satisfied whether the adjusted width is acceptable. In particular, in the case of a subject using a wheelchair, it is determined whether or not rotation is easy with this width, and an appropriate value is determined.
[0049]
The data in the meantime is collected in a personal data file of the host computer 4 from the terminal as shown in FIG.
[0050]
Similarly, if the height of the entrance bench is adjusted according to the measurement size of the subject called by the personal code to check whether it can be used successfully, the data in the meantime is collected from the terminal into the personal data file of the host computer 4.
[0051]
After the measurement at the entrance corner, the next step is to go to the toilet corner of FIG. 1 through the slope. At this time, the need for handrails can be experienced with the handrails provided on the slope. In addition, you can experience whether the communication path has better stairs than the slope.
[0052]
In the toilet corner, taking into consideration the things you can do on your own and the need for a space for the assistant around the toilet, as shown in Figure 15, decide whether the paper holder and handrail should be left or right according to your physical condition, The data is called with a personal code (for example, based on measurement data such as 8, 9, 1, 5, 12, 11, 13, 14 in FIG. 11) and is attached to a size that seems to be appropriate. The movement of getting up from the toilet at those positions is simulated and adjusted. Also, once the handrail and holder positions are determined, the right and left widths are changed by moving the wall to determine the appropriate position. In addition, move the front wall to determine the appropriate size. Data during this time is transferred to the host computer 4 and collected in a personal data file.
[0053]
After the measurement at the toilet corner is finished, the next step is to determine the height at which the washing machine is easy to use.
[0054]
In other words, it is quite difficult to take out the laundry by putting a hand in the bottom of the washing tub when getting older. Therefore, it is necessary to devise such as lowering the floor of the space where the washing machine is placed. Drum-type washing machines, which have recently become widespread, have the advantage of being able to take out laundry from the front, but they are a process of bending over. In the case of a wheelchair, it is necessary to confirm the opening angle of the front door.
[0055]
Therefore, in accordance with the measurement data of the subject who is called with the personal code, the height of the floor on which the washing machine is placed is changed as shown in FIG. Data during this time is transferred to the host computer 4 and collected in a personal data file.
[0056]
When the measurement of the washing machine is finished, the process proceeds to the bathroom (bath) corner shown in FIG. The bus has different bathroom sizes depending on physical conditions, such as whether or not there is assistance and whether or not a wheelchair is used.In addition, the presence and location of handrails and the assistance space also vary depending on the physical condition. The bathroom wall or bathtub is moved as shown in FIG. Then, the operation until entering the bathtub is simulated to adjust whether the distance is good. At this time, data may be collected assuming that a lift is used. Data during this time is transferred to the host computer 4 and collected in a personal data file.
[0057]
Next, you will experience a leveling machine. As shown in FIG. 16, the level difference canceller uses a lifting hydraulic table and experiences ease of use by moving up and down while standing or on a wheelchair.
[0058]
When this is completed, the process proceeds to the water area in FIG. Here, first, the height of the housework table is determined.
[0059]
The height and shape of the table vary depending on the type of work you do, but it greatly affects the size and physical condition of the person. Therefore, adjust the height of the table in advance to the dimension that seems to be appropriate in the data called by the personal code from the terminal, for example, ironing operation, etc., as shown in FIG. Adjust so that
[0060]
Next, the bathroom vanity is simulated. The operation of the washing surface greatly bends, so that the waist is burdened. To lighten the burden, the height of the vanity is an important point. If it is too high, the elbow will rest on the basin, and if it is too low, the knees and hips will bend and become cramped. Also, the height that is easy to use is different between when standing and using it in a wheelchair. When sitting and using, adjust the height so that the foot can fit under the counter and the basin does not hit the knee. For this reason, the height of the basin is adjusted to the size that seems to be appropriate in the data called by the personal code from the terminal, and the height is adjusted from here to find the right height. Data during this time is transferred to the host computer 4 and collected in a personal data file.
[0061]
Next, determine the height of the water sink, stove, and door pocket in Figure 1. In general, it is desirable to determine the sink, stove, and door pocket based on the individual's height. In particular, in order to make a safe facility that is easy to use for the elderly, it is necessary to know the various body functions well, and then determine the height, specifications, and shape. Therefore, with the data called by personal code from the terminal, the height of the sink is adjusted to a dimension that seems to be appropriate in advance, and the height of the sink is changed, for example, as shown in FIG. Choose the right height. Data in the meantime is transferred to the host computer 4 and collected in a personal data file.
[0062]
Similarly, select the right height by changing the height of the stove and door pocket to the size that seems to be appropriate in the data called with the personal code from the terminal. Data in the meantime is transferred to the host computer 4 and collected in a personal data file.
[0063]
After the measurement around the water, the next step is to experience the height of the stairs and handrails in Figure 1. Stairs are places where there are many accidents in the home, such as tripping and stepping off. A gentle slope is desirable, and it is important to attach a handrail. In order to make the slope easy to climb up and down, the dimensions of the tread and the kick-up are important.
[0064]
On the other hand, handrails are used to support and lift the body when climbing, and are used to maintain stability so as not to break the balance when descending.
[0065]
For this reason, here we will select the two stairs that are different from the treads and the stairs. At this time, select the one that can use the handrail with different mounting height.
[0066]
Similarly, the door is selected. The width of the door varies depending on the physical condition, how to assist, and whether or not a wheelchair is used. Here, a preferable one is selected from the three types of prepared doors and sliding doors having different widths. These data are also collected in a personal data file.
[0067]
When the door is finished, the height of the table and the tatami is selected in the living room corner of FIG. That is, when using a table for eating or resting, it is necessary to choose a comfortable chair for the elderly or a cane user, and pay attention to the relationship between the wheelchair and the height of the table. It is. In general, a slightly lower table is recommended for the elderly, but when using a wheelchair, it is important that the table has an armrest underneath and the footrest does not collide. In addition, there are those where the seating surface is lifted up and those where the seating surface is slightly higher and has a forward slope in order to make it easier to stand up. Here, a meal table is selected.
[0068]
Therefore, as shown in FIG. 18, the height of the table is adjusted to the dimension that is considered appropriate in the data called by the personal code from the terminal, and the best height is determined by simulating the eating operation.
[0069]
On the other hand, the height of the tatami mat, that is, the level difference of the threshold, is very dangerous for the elderly. In addition, a tatami space with a Japanese-style room with tatami mats set at the waist is very convenient for elderly people who have difficulty standing up.
[0070]
Therefore, here, the height of the tatami mat is adjusted to the dimension that is considered appropriate in the data called by the personal code from the terminal, and a step that is easy to move to the tatami corner is determined. Further, according to the data called by the personal code, the user can experience usability by raising and lowering the tatami mat according to the waist height as shown in FIG.
[0071]
Also select the bed height. Beds are easier than futons as legs become weaker due to aging. Therefore, an appropriate height can be determined here so that transfer to the bed can be experienced according to the physical condition.
[0072]
In other words, when you transfer by yourself. When transferring from a wheelchair. When an attendant is accompanied and transferred (especially using a lift). In this case as well, as shown in FIG. 18, the optimal height is selected by raising and lowering the bed, based on the dimensions that are considered appropriate in the data called from the terminal by the personal code. Data during this time is collected in a personal data file.
[0073]
In addition, determine the position of the switch and outlet and the height of the storage shelf. The position of the outlet switch is not good either if it is too high or too low. In particular, it is a heavy burden for elderly people and persons with disabilities who cannot bend and stretch well. Therefore, here, attach the outlet or switch with the magnet attached to the location that is considered appropriate in the data that was called from the terminal with the personal code, as shown in FIG. 19, and plug the plug into the attached outlet or switch. Select the optimum position by inserting and removing. Data during this time is collected in a personal data file.
[0074]
The storage shelf is one of the places that require the devices that are most often taken up among the facilities in the house. In addition, it is also a place that needs to be reviewed due to changes in physical functions accompanying aging. Therefore, here, the upper limit of the height (the height of the storage shelf) at which the three bags having different weights are lifted and stored on the shelf is determined.
[0075]
That is, as shown in FIG. 19, the storage shelf is moved to a height that is considered appropriate in the data called from the terminal by the personal code. Put three types of bags on the shelves in order with both hands and adjust the height to ease of use. The storage shelf is moved to a height that seems to be appropriate for the data called from the personal code from the terminal, and the data during this period is collected in a personal data file.
[0076]
In this way, data measured by each simulator is transmitted to the host computer, collected, and subjected to statistical processing, thereby creating an effective database.
[0077]
Therefore, if operated as an exhibition facility in this way, it is possible to sample a large number of data without incurring costs and obtain data of an unspecified number of people.
[0078]
In the above embodiment, the measurement is performed in order from the entrance simulation apparatus, but the measurement is not limited to this. It is not necessary to use all the simulation apparatuses, and the order is not limited to the above-described form.
[0079]
【The invention's effect】
By configuring the present invention as described above, a large number of data can be sampled without cost. In addition, data of an unspecified number of people can be obtained.
