Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments.
[0048] Such as Figure 7 As shown, a grid human body model measurement device based on wireless positioning includes a control center, four sets of wireless receiving devices with relatively fixed position coordinates, and several wireless transmitting modules attached to the surface of the human body. The wireless transmitting modules are powered on The wireless receiving device can receive the radio waves emitted by the wireless transmitting module, and feed back the collected radio wave signals to the control center.
[0049] Accurate coordinates of each wireless transmitting module are obtained by obtaining the phase difference between multiple groups of any two wireless receiving devices receiving the wireless signals of the same wireless transmitting module.
[0050] Such as figure 1As shown, the surface of the human body is c...

The invention relates to a grid human body model measuring device and method based on wireless positioning. The measuring device comprises four groups of wireless receiving devices with relatively fixed position coordinates, and a plurality of wireless transmitting modules. The wireless transmitting modules can transmit radio waves in a power-on state, and the wireless transmitting modules are attached to the surface of the human body in an array manner. The negative electrodes of each row of wireless transmitting modules are connected with each other and are connected with the negative electrode of the power supply through a group of negative electrode controllers; the positive electrodes of each column of wireless transmitting modules are connected with each other and are connected withthe positive electrode of the power supply through a group of positive electrode controllers; only one group of wireless transmitting modules is in the working state at the same time; the accurate coordinates of each wireless transmitting module are obtained by obtaining the phase difference of wireless signals, received by any two wireless receiving devices, of the same wireless transmitting module. The three-dimensional coordinate set of the human body surface is obtained by collecting the three-dimensional coordinates of the human body surface wireless transmitting modules, and then reconstruction of the human body model can be completed.
Description
technical field [0001] The invention relates to the technical field of three-dimensional lattice models of human bodies, in particular to a measuring device and method for grid human body models based on wireless positioning. Background technique [0002] Human body size and human body model, as the representation of human geometric information, have a wide range of applications in the fields of ergonomics design, clothing customization, virtual fitting and anthropological research. Existing scan-based human body reconstruction methods rely on professional equipment, which has disadvantages such as high cost of use, large amount of calculation, and easy to be affected by the environment, which limits its application scenarios. In terms of the determination of the size and relative position of the human body surface, the collection of three-dimensional point coordinate information on the human body surface can be completed by receiving the lattice coordinate signal of the hum...
