Abstract

A three-dimensional space motion reconstruction method and apparatus constructed thereby is provided, wherein a signal sensing module generates and then transmits a set of motion data to a calculating module. Thereby, the calculating module compares the motion data with a plurality of threshold values, and then produces a series of projected track signals onto a virtual plate according to those motion data that are not smaller than the threshold values. Besides, the calculating module generates a transfer matrix at the meanwhile. Finally, the calculating module further projects the series of projected track signals onto an ultimate track plate to obtain a series of two-dimensional track signals.

Description of the Invention: [Technical Field to Be Invented by the Invention] The present invention is a hybrid-brittle trace reconstruction pattern and is directed to a two-dimensional and three-dimensional reconstruction method and running in three-dimensional space. (4) - a kind of motion trajectory [previous technology] - a kind of habit _ trace reconstruction method and its device, the patented brain _ "integrated input device" revealed by the integrated-integrated input device' and the integration An image processing device controlled by a type of input device. The integrated input device has a hard-to-sensing unit, a signal processing unit and a wireless transmitting unit, so that the inertial unit is sewn into an electronic signal according to the swinging shape of the integrated input device. The electronic signal is ridiculed by the wireless transmitting unit, and the image processing is performed by the wireless transmitting unit. The image processing is displayed at the most ===, and the signal can be moved according to the cursor position signal-display device to display the cursor to the specified position. Wherein, when the input device is operated by the user to perform a yaw rotation in the three-dimensional space, the inertial sensing unit spoofs the change of the gravitational acceleration and the gravitational acceleration of the integrated input device in the -y axis The gravitational acceleration component of the direction, and the yaw rate in the -X (four) direction as the electronic signal, and converted into the two deflection angles of the X-axis and the Z-axis as the rotation axis respectively As the cursor position signal. However, since the conventional device directly converts the 201101234 wire generated by the inertial sensing unit into the cursor position signal and transmits it to the image processing device, the transfer type input device cannot correct the drift error of the bribe sensing unit. It is difficult for the user of the integrated input device to position the cursor displayed by the display device to the designated location. In addition, since the above-mentioned conventional method uses only the two-deflection angle of the integrated input device at the solid-state position as the cursor position signal, the method is obviously not applicable to the integrated input device itself in three-dimensional space.

Further, the dynamic switch unit 31 of the present invention preferably has a threshold value of a threshold value i and a speed in each of the initial axial directions; f value ~. When 'when the acceleration value TAi is to be determined, it is preferred that the sensing module i is in the -return to zero state and maintains the predetermined time ^ (4) the acceleration value of the signal system module at the predetermined time (four) 4 = After the large value, i to 3-times of the maximum value is used as the acceleration gate broadcast, and if the speed threshold value Tvi is to be determined, it is preferable to take the maximum value of the fascia value Vi within the predetermined time 〇 .5 to 丨 times the speed of the door threshold Ίνί. Referring to Fig. 2, the entanglement shows the dynamic switching unit of the present invention. The dynamic off unit 31 first receives the sense signal and sets itself to the off state. Then, a first judgment expression is executed to determine "whether the dynamic switching unit 31 is in an on state". If the result of the first judgment formula D1 ^_ is YES, the acceleration value A1 is integrated to integrate the time to obtain each of the speed values Y, and a second judgment formula D2 is executed; and if the first judgment formula D1 If the result of the determination is "NO", then 201101234 = the force 1 degree value Ai takes the absolute value - the acceleration is absolute and a third judgment formula D3 is imposed. _ early % 31 of the second judgment type is judged "whether = ==, the judgment of the second judgment formula D2] The amount of displacement in the initial axial direction 1 ^ will be 22: Day 1 into the score to obtain each得 Η _ H H acceleration value Ai takes the absolute value to obtain the D 2 pair value ^ ' and takes each of the speed values Vi to take an absolute value to obtain 1 break t D2 anger ^, and then - the fourth judgment formula D4; If the judgment result of the first = break type m is "NO", then a fifth judgment formula is executed: the third judgment formula D3 of 31 is compared with "the acceleration credit τ ^ " ^ is larger than each of the initial The acceleration gate of the clock is pre-arranged: Ai". If the judgment result of the third judgment formula 03 is that the off unit is set to the on state, and each of the acceleration values is: and the line is integrated to obtain each of the speed values Vi, the fifth judgment is performed; if the The judgment result of the three judgment formula D3 is that the first judgment formula D1 is re-executed.
