The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
Before the present invention is described in detail, be noted that in the following description content similar elements is to represent with identical numbering.
Consult Fig. 1, first preferred embodiment of the present invention is wireless body height measuring device 100 comprises a processing module 10, a wireless distance finding device 11, an image capture unit 12, a display module 14 and a memory module 15.
In order to allow the function diversification of for example general weighing machine of existing utensil, in this preferred embodiment, wireless body height measuring device 100 also comprises a weighing machine 13, weighing machine 13 in the present embodiment is electronic type platform scales, have a weight sensor 131 and an analog/digital converter 132, weight sensor 131 is with weight conversion output one analogue signal of a testee 5 (as shown in Figure 3), is digital signal by analog/digital converter 132 with this analog signal conversion, then can be conversed a gravimetric value and be controlled display module 14 by processing module 10 to show gravimetric value.
It should be noted that, among other embodiment, electronic weighbridge also can change the mechanical type platform scale into and show with pointer, perhaps, the present invention is coalition restatement 13 but need the utensil of height information in conjunction with physiologic test equipment (as: body fat meter) or body-building apparatus (as: treadmill or treadmills) or other not, not with in conjunction with being restriction as the described weighing machine 13 of present embodiment.
Consult Fig. 2, as processing module 10, wireless distance finding device 11, image capture unit 12, display module 14 and the memory module 15 of Fig. 1 be packaged in as in the shell 2 of weighing machine, shell 2 tops form a datum level and stand for testee 5, for convenience of description, below datum level is called pedal 21.
Consult Fig. 2 and Fig. 3, the image of image capture unit 12 (CMOS Image Sensor) acquisition one object is judged for processing module 10; 11 in wireless distance finding device is to be subject to processing laser or infrared ray or the supersonic wireless distance finding instrument that module 10 (as Fig. 1) drives, it should be noted that, image capture unit 12 and wireless distance finding device 11 are arranged at a pedestal 22 that slightly tilts towards testee 5, cooperate the position of testee 5 to obtain suitable image and aim at the position that desire measures whereby.
Cooperate Fig. 1 and Fig. 3, processing module 10 has a judging unit 101, a trigger element 102 and an arithmetic element 103; Judging unit 101 judges whether image capture unit 12 obtains the pre-fixing of an object, and in the present embodiment, object promptly is the hand 51 of testee 5; Trigger element 102 is subjected to trigger to drive wireless distance finding device 11 to hand 51 emission and received signals; 103 of arithmetic elements convert one between the distance value of pedal 21 with hand 51 according to received signal; Then, but display module 14 range of a signal values and memory module 15 can write down distance value.
Consult Fig. 3, the present invention is wireless, and the height method for measurement mainly comprises the steps:
At first, testee 5 stands on the pedal 21; Then, hand 51 is placed testee 5 crowns; At this moment, order about image capture unit 12 beginning pick-up images, the mode of driving can be to trigger a switch; Then, judge whether to obtain the hand image of testee 5, judgment mode can be to utilize the colour of skin to judge and utilize the eigenvalue analysis of palm; Then, obtained the hand image if judge, then ordering about the wireless distance finding device 11 that is positioned at pedal 21 automatically launches and received RF signals to the hand 51 of testee 5, and order about arithmetic element 103 and convert one between the distance value of pedal 21 with hand 51 according to received signal, then with display module 14 range of a signal values or with memory module 15 (as Fig. 1) record distance value.
Consult Fig. 4, second preferred embodiment of the wireless body height measuring device 100 ' of the present invention also comprises processing module 10, wireless distance finding device 11, image capture unit 12, display module 14 and memory module 15 as first preferred embodiment (as Fig. 1), and processing module 10 also has judging unit 101, trigger element 102 and arithmetic element 103.
What be different from first preferred embodiment is that the wireless distance finding device 11 of wireless body height measuring device 100 ' also couples a driver 111, and driver 111 is subject to processing the control of module 10 and orders about its range finding position of wireless distance finding device 11 adjustment.
Its detecting handling process is: the judging unit 101 of processing module 10 is judged its palm of the hand position after obtaining the image of hand 51 of testee 5, and calculates a deviant at the capture picture center of palm of the hand position and image capture unit 12; Then, trigger element 102 is triggered with the foundation deviant and is ordered about range finding position that driver 111 adjusts wireless distance finding devices 11 with to emission of the palm of the hand position of hand 51 and received signal; Convert one between the distance value of pedal 21 by arithmetic element 103 according to received signal again with hand 51, last, but display module 14 range of a signal values and memory module 15 can write down distance value.
In addition, can consider a vertical height (height) when testee 5 is stood and a differential seat angle of wireless distance finding device 11 emission/receiving ranges during actual conversion height, utilize this differential seat angle and emission/receiving range of recording can instead push away the correct height of testee 5; Among other embodiment, for estimating correct height, also can make testee 5 extend hand 51 parallel and perpendicular to wireless distance finding device 11 with the crown of testee 5, or be designed to utilize one can be for the flat board of image identification, so only needing that order is dull and stereotyped can be parallel with the crown of testee 5 and perpendicular to wireless distance finding device 11, then need not consider the problem of differential seat angle.
By above explanation as can be known, the wireless body height measuring device 100 of the present invention and method have following effect:
One, the present invention replaces tradition with wireless distance finding device 11 and processing module 10 and measures the up-and-down rod that heights use and measure height, and is easy to use.
Two, combination restatement 13 of the present invention, physiologic test equipment (as: body fat meter) or body-building apparatus (as: treadmill or treadmills) or other need to be measured the utensil of height information, will make existing measurement equipment immediately measure height and possess the function of a tractor serves several purposes.
