Description
Technical field
The invention belongs to mobile phone test field, a kind of method for showing handset program change procedure is especially related to.
Background technology
At present, smart mobile phone almost turns into article indispensable during people live, and the performance of smart mobile phone is also by people
Increasing concern, wherein, as one of important performance, the program of smart mobile phone is run, and is that people weigh handset capability
An important measure index.
The program operation of displaying smart mobile phone needs to cash by image, but is difficult at the time of program operation and stabilization
Accurately determined with instrument, can not often meet requirement, the displaying frame of selection is also and improper, and shadow to a certain extent
The postitallation evaluation to handset program is rung.
The content of the invention
The problem to be solved in the present invention is a kind of method for showing handset program change procedure of design, can accurately be shown
The running of handset program.
In order to achieve the above object, the technical scheme taken of the present invention is：A kind of side for showing handset program change procedure
Method, it is characterised in that comprise the following steps：
(1) test system is built, including mobile phone to be measured, and high frame per second camera device, the mobile phone is being placed in camera device just
To direction；Also include mobile phone control equipment, start to trigger and run；
(2) need to demarcate camera before testing, to reduce the distortion of image；
(3) key frame of handset program change is chosen.
It is preferred that, the distance of mobile phone described in the step (1) and the high frame per second camera device is 25cm.
It is preferred that, the method for demarcation is, it is necessary to using scaling board, scaling board can be shot in camera in the step (2)
Sectional drawing is carried out in the regional arrived.Then each angle point photographed is calculated according to image, the perspective with reference to camera is abnormal
Become formula, Parameters in Formula is fitted, final distortion parameter is obtained.The image photographed is carried out using its parameter last
Correction, is used as follow-up pending image.
Further, the scaling board is the scaling board of 8*11 angle point.
It is preferred that, the key frame chosen in the step (3) includes stabilizer frame and changing frame.
Further, the choosing method of the stabilizer frame is：
Firstly the need of one threshold value n of setting；
Secondly present image is compared with rear n two field pictures, when image does not all change, is defined as stabilizer frame.
Further, the choosing method of the changing frame is：
Firstly the need of one threshold value n of setting；
Secondly present image is compared with preceding n two field pictures, when image, which exists, to be changed, candidate change can be entered
Frame.
3rd determines whether noise using the method for connected domain, if not noise, then is between n image before judging
It is no to change, if do not changed, illustrate before be all inactive state, such present image is then changing frame.
Further, if the determination methods for being noise are：Judged by way of connected domain；Obtain the connection of image
Domain component, compares the point set number in each component, is the influence that noise is caused if point set is less than the threshold value of setting, no
It is then image change.
Further, frame difference method is relatively used between the frame and frame, both, which change, is more than the threshold value set then image
Change.
The present invention is by choosing key frame, the process of displaying handset program change, and key frame becomes further through the program of selection
Stabilizer frame and changing frame in change realize that ensure that mobile phone science, the change of accurate presentation program, this method is simply easy
OK, choose accurate, effective display data can be obtained, obtain satisfied effect, the running state of programs of smart mobile phone is commented
Survey and provide accurately foundation.

Embodiment
With reference to specific embodiment, the present invention is described further.
First, system constructing
The testing mobile phone reaction time includes the startup time, the time for reaching certain specified icons position, mobile phone of test program
The reaction time such as on ＆ off switch and side switch.When being explained herein by taking the startup time of mobile phone Program as an example, but being not limited to start
Between.The camera of a high frame per second is needed to be used for the overall process for shooting handset starting in this programme, as shown in figure 1, wherein 101 represent
Camera, is placed in the top of mobile phone, and 102 be that mobile phone is right against camera.In order to improve picture quality and reduce external light source
Influence, can add light shield.103 be mobile phone control equipment in figure, starts to trigger and runs.
2nd, pre-process
Need to demarcate camera before test, to reduce the distortion of image., it is necessary to use demarcation in calibration process
Plate, according to the distance of camera and mobile phone (it is 25cm to be more than), herein from the scaling board of 8*11 angle point, as shown in Figure 2.It is real
In the operating process of border, scaling board is allowed to carry out sectional drawing in the regional that camera can be photographed.Then calculated according to image
Each angle point photographed, with reference to the perspective distortion formula of camera, is fitted to Parameters in Formula, obtains final distortion ginseng
Number.The image photographed is finally corrected using its parameter, follow-up pending image is used as.
3rd, key frame is calculated
Calculate the process that key frame is used to show handset program change to user.Key frame includes stabilizer frame, that is, moves to
Current frame image when static, and changing frame, i.e., from the static current frame image just moved.
The specific calculating process for calculating stabilizer frame is as shown in Figure 3.
Program is firstly the need of one threshold value n of setting, when n two field pictures do not change, it is believed that image is stable state.This
Sample present image is compared with rear n two field pictures, and specific comparative approach can utilize frames differencing method.When image does not all become
During change, it may be determined that be stabilizer frame.
The value for calculating the threshold value n of stabilizer frame is chosen for 5.
The specific calculating process for calculating changing frame is as shown in Figure 4.
Program is firstly the need of one threshold value n of setting, when present image is changed compared with preceding n two field pictures, then it is believed that should
Frame has change.So present image is compared with preceding n two field pictures, and specific comparative approach can utilize frames differencing
Method.When image, which exists, to be changed, candidate change frame can be entered.The method of connected domain is recycled to determine whether noise, if
Be not noise words, then whether changed between n image before judging, if do not changed, illustrate before be all inactive state,
So present image is then changing frame.
The value for calculating the threshold value n of changing frame is chosen for 5.
Wherein, if the determination methods for being noise are：Judged by way of connected domain；Obtain the connected domain point of image
Amount, compares the point set number in each component, is to make an uproar if point set is less than the threshold value (threshold value set here is 10) set
The influence that sound is caused, is otherwise image change.
Frame difference method is relatively used between frame and frame described above, both change the threshold value (threshold value setting more than setting
For 5) then image is changed.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be considered as the practical range for limiting the present invention.All equivalent changes made according to the present patent application scope and improvement
Deng within the patent covering scope that all should still belong to the present invention.
