Moreover, each lifting adjusting column 130 is provided with a sensing assembly, and the sensing assembly is mounted at the upper end of the lifting adjusting column 130, wherein the sensing assembly comprises a displacement sensor and a pressure sensor, in this embodiment, the displacement sensor is located between the lifting adjusting column 130 and the pressure sensor, the pressure sensor is used for collecting pressure values of the lifting adjusting column 130 when a person to be tested lies down in real time, and the displacement sensor is used for collecting up-down displacement values of the lifting adjusting column 130 in real time.
The support cushion 120 is disposed on the test stand 110 and covers the opening of the accommodating groove 111, and the lower surface of the support cushion 120 abuts against each lifting adjustment column 130, that is, all the lifting adjustment columns 130 provide a supporting effect for the support cushion 120. In this embodiment, the support cushion 120 may be a soft cushion pad, and the inner material may include, but is not limited to, soft materials such as memory cotton and latex. The support cushion 120 may have a rectangular shape when viewed from above.
It can be understood that when the subject lies on the support cushion 120, the support cushion 120 applies pressure to the lifting adjusting column 130 below the support cushion 120, and the pressure sensor can detect the pressure value received by the lifting adjusting column 130. When the elevation adjustment column 130 is controlled to move in the up-down direction of the support platform, the displacement sensor can detect the up-down displacement value of the corresponding elevation adjustment column 130.
The camera shooting mechanism is arranged above the support cushion 120, and can horizontally move relative to the support cushion 120, so that the camera shooting mechanism can shoot a person to be tested lying on the support cushion 120, and human body image data on the support cushion 120 are acquired.
The upper computer 170 may be mounted on a support platform through a support frame. The upper computer 170 is electrically connected to all the lifting adjusting columns 130 through cables, and the upper computer 170 can drive each lifting adjusting column 130 to move along the up-down direction.
The upper computer 170 is electrically connected to the sensing assembly and the camera mechanism through cables, so that the upper computer 170 can receive the human body image data collected by the camera mechanism to generate front profile three-dimensional data of the tested person, can receive the displacement data collected by the displacement sensor to generate back profile three-dimensional data of the tested person, and then generates a complete lying human body three-dimensional model according to the front profile three-dimensional data and the back profile three-dimensional data. In addition, the upper computer 170 can receive the pressure data collected by the pressure sensor to obtain a pressure distribution map, thereby displaying the pressure distribution of the support cushion 120.
It can be understood that the upper computer 170 includes a control module, a storage module, a calculation module and a display module, wherein the control module can be a main control board, and the control module can control the camera mechanism and the lifting adjusting column 130 to move according to the input command; the storage module can be a memory, and is mainly used for storing data, such as body type data, displacement data, pressure data and the like of all tested persons, and a database with body types matched with the mattress is stored in the storage module; the calculation module can be a data processor, is internally provided with an algorithm, and can calculate according to the received data so as to generate corresponding three-dimensional data, pressure distribution diagrams and the like; the display module can be a display screen and can display information such as data, models, reports, mattress customization schemes and the like. The host computer 170 can generate an image by calculation and display the result.
It will be appreciated that, in the process of using the bed selecting system of the present embodiment, when a person to be tested lies on the support cushion 120, the person to be tested applies a pressure to the support cushion 120, at this time, the lower surface of the support cushion 120 contacts each lifting adjusting column 130, and the pressure sensor collects the pressure value received by the lifting adjusting column 130 corresponding thereto, and the pressure sensor sends the collected pressure data to the upper computer 170.
Then, the user can operate the upper computer 170 to adjust the up and down positions of the corresponding lifting adjusting column 130 according to the comfort level of different parts of the tested person (such as comfort level of support of different parts of head and neck, shoulder, waist, legs, etc.), and can also adjust the up and down positions of the corresponding lifting adjusting column 130 according to the pressure value condition of the lifting adjusting column 130, so that the tested person subjectively feels comfortable, and at this time, the tested person is in the optimal lying state.
In the process of adjusting the lifting adjusting column 130, the displacement sensor records the up-down displacement data generated by the lifting adjusting column 130, and the displacement sensor sends the collected displacement data to the upper computer 170. After receiving the displacement data, the upper computer 170 can generate back profile three-dimensional data of the subject by calculation processing.
Meanwhile, the upper computer 170 controls the camera to move, the camera is used for collecting images of the testee, and the camera can send collected image data to the upper computer 170. After the image data is obtained, the host computer 170 can generate three-dimensional data of the front outline of the subject by calculation processing.
Then, the upper computer 170 generates a human body three-dimensional model according to the obtained front outline three-dimensional data and back outline three-dimensional data, so that the human body three-dimensional model can be searched and searched according to a database of body shapes and mattresses, and the human body three-dimensional model can be accurately matched with a mattress customization scheme.
By adopting the structure, the bed selecting system can more accurately adjust the lying posture of the tested person to be the most comfortable, can nondestructively detect the lying posture of the tested person, and can complete the work of building the three-dimensional model so as to more scientifically and accurately select the most suitable mattress.
The bed selecting system of the embodiment can effectively solve the problems that a tested person in the prior art can easily be damaged by ionizing radiation such as X rays and the like when body scanning and body type detection are carried out during lying.
Because the body type scanning equipment on the market can only acquire the body type of the testee when standing, and the body type form is inconsistent when standing and lying, if the mattress is selected based on the body type form when standing, mismatch is easy to occur, the bed selecting system of the embodiment can acquire the model of the body type form of the testee when lying in nondestructive testing, and further can scientifically, strictly and accurately select the mattress, and the problem that only the standing model of the testee can be acquired in the nondestructive scanning testing in the prior art, and the body type posture model of the testee when lying in the lying state cannot be acquired is effectively solved.
In the bed selecting system of the embodiment, when a person to be tested lies on the support cushion 120, the height of the upper surface of each small part of the support cushion 120 can be adjusted by the lifting adjusting column 130 below the support cushion 120 according to the requirement of the person to be tested, so that the person to be tested can find a model in the most comfortable lying posture, and the mattress can be accurately selected; in addition, the lifting adjusting column 130 can be controlled to displace according to the collected and recorded pressure distribution data so as to carry out fine adjustment, and the tested person is ensured to be in an optimal lying body type form; through the double-layer standard of the most comfortable lying posture, namely the body type and the pressure distribution condition, more accurate bed selection is realized.
It will be appreciated that mattresses have resilience parameter properties in addition to softness parameter properties. Because people often sleep in a dynamic process, the situations of body turning, sleeping posture switching and the like can be involved in the sleeping period, the matched mattress is required to calculate the rebound degree parameters of the mattress according to different body types besides pursuing proper hardness, so that the rebound degree of the mattress meets the requirement. When the rebound degree of the mattress is matched properly, the user can easily adjust the sleeping posture on the mattress without feeling, and the sleeping is not interrupted, so that the sleeping quality is improved effectively. In the couch selection system of the embodiment, not only the back profile three-dimensional data of the subject but also the front profile three-dimensional data of the subject are considered, so that the back profile three-dimensional data and the front profile three-dimensional data are combined to establish a human body three-dimensional model when lying.
It can be understood that the database of body type and mattress mentioned in this embodiment is a research result in the statistical field for the body type and mattress parameters of the user, where the body type parameters of the user include but are not limited to gender, height, weight, age, back contour, body type, etc., different databases have different statistical rules, which can be iteratively adjusted according to the actual situation, and the mattress parameters include but are not limited to softness, rebound degree, etc.
Through the test and experience of a large number of consumers, the best mattress is matched and evaluated, and then, according to the test data, the body type parameters of the user and the mattress parameters are mapped correspondingly, so that a database of body type and mattress is established. The main parameters influencing the matching relation are found through a statistical tool, so that the total of the parameters is ensured to have higher correlation coefficients, and the parameters have statistical significance in a 95% confidence interval. Thus, the creation of a database of body shapes and mattresses can be accomplished in the existing manner described above.
