The right side, can be tied up on the limbs such as ankle or arm, and without prejudice to is moved.
A kind of running training system based on virtual reality technology of the present invention in the environment of having WIFI, it is necessary to run, tool
Body signal transacting and the program circuit of control program are：
Step one：Historical data is removed, parameter preset, the parameter includes runner's leg length and cycle-index n；
Step 2：The opening program of the computer usb interfaces of receiving terminal 10 grafting of bluetooth is driven, computer 3, which is received, to be run
The angle signal that gyroscope accelerometer 5 is gathered when step person uprightly wears velocity package, the angle signal is with binary signal shape
Formula is inputted into computer, and computer is received after the angle signal, (should according to the angle calculation formula of gyroscope accelerometer 5
Formula is explicitly recited on the specification of gyroscope accelerometer 5) obtain initial angle；
Step 3：Runner's setting in motion, computer 3 receives the angle that a gyroscope accelerometer 5 is gathered per Δ t ms
Signal is spent, computer 3 can persistently receive the n signal provided by gyroscope accelerometer 5, n group data are obtained；Further according to top
The angle calculation formula of spiral shell instrument accelerometer 5 obtains the angle at current time, be fixed interval variation, it is rhythmic, have
The walk-off angle angle value of peak value, and the time of record collection n group data is t, t=Δ t*n, unit ms；The Δ t with it is specifically used
Gyroscope accelerometer model it is relevant；
Step 4：Calculate take a step step-length and the number of times taken a step forward：
The angle at whole current times that step 3 is obtained subtracts the initial angle that step 2 is tried to achieve, obtain one group it is relative
Angle, it is degree that maximum θ, θ unit are chosen in relative angle, long in conjunction with known runner's leg, by trigonometric function
With the calculating of Pythagorean theorem, corresponding maximum step-length of taking a step under the maximum is obtained；
Set angle deviation range is [θ -10, θ], when the relative angle at the current time recorded in time t is at this angle
Spend in deviation range, be designated as people's leg and stepped a step, the timing statisticses t interior relative angles in this angular deviation range forward
Number, the relative angle number is the number of times taken a step forward for people's leg；
Step 5：Calculate velocity：
The time t of obtained n data of step-length divided by collection of taking a step is calculated with step 4, multiplied by time to take a step forward
Number, obtains the velocity of runner；
Step 6：Rate limitation：
Setting speed is limited to 0.5-1.5m/s；Work as the difference for the velocity twice that velocity variable, i.e. step 5 are obtained
Value, outpace limitation when, the speed of running is scaled to video playout speed in new broadcasting frame number, control computer 3, held
Row step 7；When velocity variable is not less than rate limitation, video is still played with former frame number, returns and performs step 3；Set
Make to have an elasticity interval for 0.5-1.5m/s rate limitation, so will not because of the of short duration suddenly speedup of runner or
Slow down and change the speed of video playback；In actual experiment, selection rate limitation is 1m/s；
Step 7：When outpace limitation after, mobile phone can eject the broadcast window of a new video, click on broadcast button
Broadcasting speed that just can be new plays video, return to step three.
N is set to 15-30 in present system, and cycle-index is more, and the time of road-work is longer.
A kind of application method of the running training system based on virtual reality technology of the present invention is：It is first in WIFI environment
First, velocity package 2 is fixed on unilateral shank by runner, and head takes the VR glasses 4 equipped with mobile phone, opens velocity package 2
On power switch 9, while opening to signal transacting and control and the computer 3 equipped with video image, original place is stood 3 seconds
Clock, to read initial angle angle value；Then, runner starts to run on treadmill 1, and gyroscope accelerometer 5 collects race
After the angle signal of step person's list leg movement, data processing is carried out by Bluetooth wireless transmission to computer 3, per second broadcast is obtained
Frame number is put, to control to play video speed；Mobile phone and computer synchronously play video image by multi-screen interactive, and runner exists
On VR glasses 4 equipped with mobile phone, it is seen that 3D " honourable on the way " image of broadcasting corresponding with velocity；After the completion of running, close
The power switch 9 closed on velocity package 2, shuts down computer 3, unties velocity package 2.When reusing, opening program can be automatic
Remove historical data.
A kind of video playback application multi-screen interactive software (hand of the running training system based on virtual reality technology of the present invention
The interaction of machine screen and computer screen, makes computer screen image project on mobile phone screen.Needed using multi-screen interactive software
To be used in WIFI environment.) technology, control mobile phone is synchronous with computer 3 to play video image.Mobile phone is put into VR glasses
In, by optical transition, planar video will be changed into 3D effect.Multi-screen interactive software described here is existing software.
Velocity package 2 can be worn on the optional position of single leg or arm by present system in acquisition angles signal,
The difference of taking a step of each step of runner is considered, the scope that have chosen 10 degree less than maximum is angular deviation range, at this
All regard the maximum relative angle before people's leg is marched toward in angular deviation range as, count the relative angle in this angular deviation range
Number.As n=20,20 relative angle numerical points of collection are linked to be line, the waveform of similar sinusoidal form, highest can be formed
Crest be exactly maximum in this group of data, the step-length taken a step is tried to achieve with this maximum.The numerical value of each crest differs
Sample, so setting an angular deviation range, once takes a step in this angular deviation range even if reaching, can thus find
Reach the number of times of crest in institute's acquisition time, crest number be exactly the number of times taken a step.
Component involved in the present invention can not be addressed part and be applied to prior art by commercially available.
