Due to reference model and panoramic video image corresponding relationship it is known that and be equally the object module of dummy model just Can easily obtain with the reference model corresponding relationship, if the object module be static object, reference model with Object module is opposing stationary in full-view image video playing.
Specifically, the panoramic video image includes two reference objects 14, the travel distance of the reference object it is known that The reference object can choose it is multiple, choose the more reference models of quantity it is more accurate, in the present embodiment, the reference object is shown On the spherical curtain, reference model is corresponding with reference object, and starting and ending is described to generate one depending on reference object Stealthy reference model includes:
According to the reference object obtain reference model size and reference model with it is corresponding in panoramic video image Position;
According in panoramic video image between reference object the broadcasting time difference and the travel distance obtain reference model Movement relation between virtual lens.
Actual range known to the present embodiment between reference object can also obtain the image of the reference object in image To obtain position on video time line, then be further able to obtain broadcasting speed between reference object, so as in the hope of Movement relation between reference model and virtual lens out, that is, play when reference model and virtual lens between it is opposite Speed.
The display module is for showing the image data;
The acquisition module is instructed for acquisition control, and control instruction described in the present embodiment is touch command, by adopting Collect touch control gesture acquisition.
The control module is used to play the panoramic video shadow on the spherical curtain according to control instruction control Picture simultaneously moves the object module according to the movement relation in panoramic video image.
It further, further include an instruction model 16 in the image data.The instruction model can in the present embodiment Think person model, animal model, cartoon model etc., the instruction model is person model in the present embodiment.
The control module is used for:
When the control instruction is the control instruction advanced, the panoramic video image positive sequence broadcasting, the finger are controlled Representation model shows the model movement walked to observation point observed direction, the object module according to the movement relation along the sight It is mobile to survey contrary direction;
When the control instruction is the control instruction retreated, the panoramic video image Reverse Play, the finger are controlled Representation model shows that the model movement walked to the opposite direction of observation point observed direction, the object module are closed according to the movement System moves along the observed direction.
The terminal device further includes a detection module and an adjustment module,
Whether the imaging point that the detection device is used to detect on the object module is in the spherical curtain, if not Then the object module is projected on the spherical curtain and being superimposed upon on panoramic video image;
The adjustment module adjusts object module in spherical curtain for the distance according to object module apart from the observation point On size, the bigger projection size of distance apart from the observation point is smaller, the smaller projection ruler of distance apart from the observation point It is very little bigger.
Referring to fig. 2, using above-mentioned terminal device, the present embodiment also provides a kind of image generating method, comprising:
Step 100 obtains a panoramic video image;
Step 101 generates a stealthy reference model, and the size of the reference model is according in the panoramic video image Object obtain;
Step 102 adds an object module in the reference model;
Step 103 generates the shadow for digital guide to visitors according to the panoramic video image, reference model and object module As data.
The step 101 includes:
According to the reference object obtain reference model size and reference model with it is corresponding in panoramic video image Position;
According in panoramic video image between reference object the broadcasting time difference and the travel distance obtain reference model Movement relation between virtual lens.
Step 100 to step 103 can be completed in manufacturer side.
Step 104, the display image data, and acquisition control instructs;
Step 105 plays the panoramic video image on the spherical curtain and complete according to control instruction control According to the mobile object module of the movement relation in scape video image.
Step 105 specifically includes:
When the control instruction is the control instruction advanced, the panoramic video image positive sequence broadcasting, the instruction are controlled The movement of model that model display is walked to observation point observed direction, the object module are according to the movement relation along the observation Contrary direction is mobile;
When the control instruction is the control instruction retreated, the panoramic video image Reverse Play, the instruction are controlled Model display is to the model that the opposite direction of observation point observed direction is walked acts, the object module is according to the movement relation It is moved along the observed direction.
Further, the present embodiment specifically defines the movement relation in step 101, since video camera when shooting can not It realizes straight ahead, has some offsets, records photographing fills the panoramic video image of the present embodiment on the time line when shooting The rotational angular velocity and acceleration set are obtained by gyroscope and acceleration transducer respectively.
The present embodiment adjusts the movement relation by two ways:
The first is the target trajectory detected in filming apparatus according to the rotational angular velocity, and the target moves rail Mark includes that level turns left first angle, then rotates second angle horizontally to the right, and then level turns left third angle The first motion profile and level turn left fourth angle, then rotate the 5th angle horizontally to the right, then it is horizontal to the left Rotate the second motion profile of hexagonal degree;
Reference model is reduced on the time line position of the target trajectory relative to virtual lens movement velocity, Middle reference model is preset value relative to the average speed that virtual lens move.
It is for second to detect the absolute value of acceleration whether to be greater than preset value, if then according to the positive negative regulator institute of acceleration Movement relation is stated, then increases reference model when being accelerated forwardly relative to virtual lens movement velocity, then subtracts when accelerating backward Small reference model is relative to virtual lens movement velocity.
It is described to show that the image data includes:
Detect whether the imaging point on the object module is in the spherical curtain, if otherwise by the object module On projection to the spherical curtain and it is superimposed upon on panoramic video image;
