Description

Apparatus and method for measuring and analysis of hand}

The present invention relates to a hand measuring device and method capable of measuring the area, angle and length of each part or the whole as well as the shape of the hand.

With the invention of a machine that replaces human hands, a factory-made machinery industry was created instead of a factory-made handwork. This enabled mass production and brought a rich world to mankind.

Many inventions in transportation and telecommunications have broken down rural and urban walls, speeding up the spread of culture, and bringing the world together. This spirit of invention of the Industrial Revolution continues to this day and various inventions for the development of humanity are being made.

The industrial revolution gave us an opportunity to move from an agricultural society to an industrial society. Thus, the Industrial Revolution is the best revolution since the beginning of Neolithic agriculture (also called the Neolithic Revolution).

As such, despite the rapid industrial development and the development of computers and the Internet, the human hand holds an important position in various industrial fields.

This is because hands are the most efficient means of performing complex tasks because of their ability to perform certain tasks that require agility, handling, and feel.

Specifically, the apparel industry varies from general gloves (cotton gloves, leather gloves) to industrial gloves, sports gloves, work gloves or special gloves such as military or fire fighting and medical gloves.

Other farm-related tools (scythes, saws, shovels, etc.), the automotive industry (handle, transmission and various operating device designs), sports equipment manufacturers, computer keyboards and mice, various hand tool designs and device operating handle designs. Measurement data is required.

In order to measure these hands, ISO or JIS has already defined the measurement items to measure, and in 2006, the Ministry of Commerce and Industry set the criteria for measurement of hand parts.

The measurement method of the trunk of the human body has been tried in different ways many times, but the measurement method of the distal end of the human body, especially the hand, is measured one by one with a Martin anthropometer.

By the way, the direct anthropometric method using the Martin anthropometer uses a measuring device such as a caliper, tape measure, weight scale, height meter, and has a merit that a measurement tool is simple and easy to measure movement, but there is always a possibility of error in measurement and writing, There is a problem that the subject's rejection.

In particular, since there are several to hundreds of measurement items in hand measurement, it is not only time-consuming and expensive to measure a large number of people, but also makes measuring devices or develops methods for measuring hands. I never did.

Therefore, there is a need for a measuring device capable of measuring the hands of many people in a short time.

Hand-related industrial products, on the other hand, instead of providing inherent functions, affect working ability. The capacity of work is influenced by dexterity, task time, grip strength, and range of motion. Therefore, providing the original function while not degrading agility, grip, and handling ability is the most important in making hand-related products.

At present, however, the dimensions and patterns of various hand-related industrial products depend on experience, not on scientific basis. Anthropometric data are not used or only provide general orientation and are problematic for applying hand measurements to product dimensions.

In particular, medical, protective and sports gloves are required to fit as well as the performance of gloves, but detailed measurements of hand parts have not been found since the 1997 National Standard Position Survey.

In the design of industrial products, the dimensions of the human body are inevitably used, and in particular, the production of garment accessories such as gloves requires various measurement dimensions of the hands. Gloves produced or sold in Korea have various uses such as cold protection, home use, medical use, sports use, and protection, and have various forms. Therefore, different hand dimensions are required for different glove designs.

Currently, only the basic items such as hand length, hand circumference, hand width, hand thickness, etc., are very low in customer satisfaction on the size of gloves. Since there is no protocol for measuring hand size to determine size, the method of measuring hand area used in the 5th human body size survey project has not been standardized.

The present invention has been made in view of the above, by taking a hand using a camera and by measuring the necessary items from the captured image through the automatic recognition program, it is easy to measure the hands of many people at once It is possible to measure and build up the measurement results into data (DB) and digitize and visualize them, so that the collected data can be used for the design of various hand tools and the handles of the machine operation to produce more convenient and hand-made products.

First, the connecting cable 17 is connected so that the camera 29 and the computer 30 come online, and the display unit 32 checks whether the camera 29 is in an on state (FIG. 13). At this time, the power of the computer 30 can be supplied to the camera 29 through the connecting cable 17, the light irradiated from the lighting panel 24 of the lower case 10 is shining on the hand with a uniform brightness. Lose.

Next, the subject's hand is inserted into the hand inlet 11 of the case 10. The posture of the hand may take various poses for the measurement of the parts of the hand, but in one embodiment of the present invention, the hand is measured in a completely flat state.

At this time, the video is displayed on the display unit 32 in real time through the camera 29, select the 'camera' from the menu on the upper left and click the 'shooting' button, the video shot by the camera 29 is a still image Is displayed on the display unit 32 (Fig. 14).

When the "Save as file" button is clicked on the same screen, a "Save as other file" message box appears (FIG. 15), and the desired file name is entered to save the video as an image file. ) And can be recalled at any time. In addition, when the "Save to DB" button is clicked, it is stored in the DB in the form of an image (Fig. 16).

17 shows a screen of the display unit 32 displaying the result stored in the DB.

Subsequently, with "Measure" selected in the menu, click "Open Image" (FIG. 18) to bring up the previously saved image file (FIG. 19). When the measurement file is selected as the wrist point designation mode while the image file previously stored on the display unit 32 reappears, and the user selects "Automatic contour recognition" among the shortcut menus displayed when the right mouse button is pressed (Fig. 20), a border line (outline) around the hand is automatically recognized by the automatic recognition program and appears on the display unit 32 (FIG. 21).

Then, when "automatic recognition contour length calculation" is selected from the shortcut menu that appears when the right mouse button is pressed on the same screen (Fig. 22), the measurement result measured by the measuring unit 36 is displayed through a message box. After selecting an item to be input in the message box as the length and pressing the input (FIG. 23), the total length of the circumference of the hand circumference in the DB storage unit 34 is stored numerically.

Then, when selecting the "automatic contour area calculation" from the shortcut menu that appears when the right mouse button is pressed on the same screen (Fig. 24), the measurement result measured by the measuring unit 36 is displayed through a message box, After selecting an item to be input in the message box as the area and pressing the input (FIG. 25), the total area inside the circumference of the hand is stored in the DB storage unit 34 numerically.

If the area calculation "is selected (FIG. 32), the measurement result is displayed through a message box, and if the item to be input is selected and inputted, the closed curve area around the selected hand is stored in the DB storage unit 34.

In addition, when measuring the width of the bottom of the second node of the little finger, the measurement mode is selected as a straight length (Fig. 33), and using the pointing means to point to the start point and the end point, then calculated by the measurement unit to store the DB The length of the straight line of the finger node selected in the section 34 is stored.

In addition, when measuring the finger open angle with the hand open, when the auxiliary line is clicked using the mouse shortcut menu bar, horizontal and vertical lines appear on the screen in parallel. At this time, it is preferable to measure the hand open angle by spreading the fingers at a uniform angle, but even if the subject tries to spread evenly, there is no reference line and there is no way to check whether the open evenly.

Therefore, in order to solve such a problem, as shown in FIGS. 41 and 42, the hand is inserted so that the wrist boundary is positioned on the horizontal line at the bottom while the auxiliary line is on the screen, and then the center line of the vertical line is placed. If the center of the middle of the middle finger and the index finger and the ring finger in contact with the inside inwards, the thumb and pinky will be spread evenly. After opening hands in this manner, the open hand angle can be measured uniformly.

At this time, the color change of the auxiliary line, the line spacing and the line thickness can be set (FIG. 41), and the distance between each horizontal line and the vertical line can be adjusted according to the size of the hand every measurement, thereby completely eliminating the error of overlapping the left and right hands of the subject. This can be done (FIGS. 43 and 44). That is, since the left and right hands are aligned under the same conditions by the horizontal and vertical lines, the error due to the overlapping hands is excluded.

In addition, when measuring the open angle between the little finger and the ring finger, the measurement mode is selected as the normal angle (Fig. 34), the center line of the finger is designated by using a pointing means, and then calculated by the measurement unit to store the DB The selected angle is stored in the section 34.

According to the present invention, the strains of the left and right hands can be visualized or digitized by overlapping the shapes of the left and right hands on the computer 30 screen.

First, the left or right hand is inserted into the hand inlet 11 while the measurement mode is designated as the hand point designation mode and stored in the DB storage unit 34, and then the image of one of the two hands (the left hand) is called up (Fig. 35). ). Then, select "automatic contour recognition" from the shortcut menu of the right mouse button (FIG. 36), and change the measurement mode to the contour portion selection mode, leaving only the border around the hand on the display unit 32 (FIG. 37).

Continue by importing the image of the other hand (right hand) of both hands, and then select "automatic contour recognition" in the same way as above, and change the measurement mode to the contour portion selection mode, only the border around the right hand on the display unit 32 If you select "Add to automatic recognition contour comparison analysis window" from the shortcut menu of the right mouse button (Fig. 38), a message box for inputting a curve name to be added is displayed (Fig. 39).

Thereafter, the contours of both hands appear in the automatic recognition contour comparison analysis window (FIG. 40), so that the strain of the left and right hands can be visualized. At this time, the automatic recognition contour comparison analysis window has a "change left and right" function in order to match each finger of the left and right hands, it is possible to match one hand to the other hand.

The number of measurement items according to the measurement mode can be infinitely extended by the user of the automatic recognition program, and the device according to the present invention is made for hand measurement, but foot measurement is also possible.

According to the present invention, it is possible to visualize and digitize all data necessary for designing a product in the current hand-related industry, and by constructing such a measurement result as a DB, it will be used in various forms in the hand-related product.
