Abstract
The invention provides a method for displaying the mobile phone program change process. The method includes the step 101 of calibrating a camera, the step 102 of selecting key frames of mobile phone program changes. The key frames include the stable frame and the changing frame. The method for selecting the stable frame includes the steps of firstly, setting a threshold value n; secondly, comparing a current image with rear n frames of images, and determining the frame of the current image as the stable frame when the rear n frames of images do not change. The method for selecting the changing frame includes the steps of firstly, setting a threshold value m; secondly, comparing the current image with front m frames of images, and determining the frame of the current image as a candidate changing frame when the front m frames of images change; thirdly, judging whether noise exists or not through the connected domain method, judging whether the front m images change if no noise exists, judging that the front m images are in the static state if the front m images do not change, and judging the frame of the current image as the changing frame.
Description
Technical field
The invention belongs to mobile phone test field, particularly relate to a kind of method of showing handset program change procedure.
Background technology
At present, smart mobile phone almost becomes article indispensable in people's life, and the performance of smart mobile phone is also subject to people and more and more pays close attention to, wherein, as one of important performance, the program of smart mobile phone is run, and is the important measure index that people weigh handset capability.
Show that the program of smart mobile phone is run to need to be cashed by image, but program is run and the stable moment is difficult to accurately determine with instrument, often cannot meet the demands, the displaying frame chosen also and improper, and have impact on the postitallation evaluation to handset program to a certain extent.
Summary of the invention
The problem to be solved in the present invention is a kind of method of showing handset program change procedure of design, can show the operational process of handset program accurately.
In order to achieve the above object, the technical scheme that the present invention takes is:
Show a method for handset program change procedure, it is characterized in that, comprise the steps:
Step 101, camera to be demarcated; Concrete calibration process is:
Use scaling board, be beneficial to camera and carry out sectional drawing in the regional of scaling board, then calculate each angle point photographed according to image, in conjunction with the perspective distortion formula of camera, matching is carried out to Parameters in Formula, obtain final distortion parameter.Its parameter is utilized to correct the image photographed, as follow-up pending image;
Step 102, choose handset program change key frame; Described key frame comprises stabilizer frame and changing frame; Wherein:
The choosing method of described stabilizer frame is: first need setting threshold value n; Secondly present image and rear n two field picture are compared, when image does not all change, be defined as stabilizer frame;
The choosing method of described changing frame is: first need setting threshold value m; Secondly present image and front m two field picture are compared, when image exists change, candidate change frame can be entered; Whether finally utilize the method for connected domain to determine whether noise, if not noise, then change between m image before judging, if not change, be then all stationary state before judging, such present image is then changing frame.
Further:
Described scaling board is the scaling board of 8*11 angle point.
The determination methods of noise is: judged by the mode of connected domain; Obtain the connected domain component of image, compare the point set number in each component, if point set is less than the threshold value of setting, be then the impact that noise causes, otherwise be image change.
Being frame difference method to what adopt during comparing between frame with frame, be specially: when the difference of two two field pictures is greater than the threshold value of setting, then process decision chart picture changes.
The present invention is by choosing key frame, show the process of handset program change, and key frame is by choosing stabilizer frame in change of program and changing frame realizes, mobile phone science, presentation program change accurately can be ensured, the method is simple, chooses accurately, can obtain effective display data, obtain satisfied effect, foundation is accurately provided to the running state of programs evaluation and test of smart mobile phone.

Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
Refer to Fig. 1, a kind of method of showing handset program change procedure, the method realizes based on test macro below:
System constructing
The testing mobile phone reaction time comprises the reaction time such as the start-up time of test procedure, the time arriving certain specified icons position, handset switch key and side switch.This specific embodiment was explained for the start-up time of mobile phone Program, but was not limited to start-up time.Need a camera for taking the overall process of handset starting in this specific embodiment, as shown in Figure 1, this test macro comprises camera 1, mobile phone 2 and mobile phone opertaing device 3; Camera 1 is positioned at the top of mobile phone 2, in order to improve picture quality and reduce the impact of external light source, can add light shield.Mobile phone opertaing device 3 is in order to trigger start-up and operation.
Refer to Fig. 2, Fig. 3, Fig. 4, a kind of method of showing handset program change procedure, comprises the steps:
Pre-service
Need before test to demarcate camera, to reduce the distortion of image.In calibration process, need to use scaling board, according to the distance of camera and mobile phone, select the scaling board of 8*11 angle point herein, as shown in Figure 2.
In actual mechanical process, scaling board is allowed to carry out sectional drawing in the regional that camera can photograph.Then calculate each angle point photographed according to image, in conjunction with the perspective distortion formula of camera, matching is carried out to Parameters in Formula, obtain final distortion parameter.Its parameter is utilized finally to correct the image photographed, as follow-up pending image.
Calculate key frame
Calculate key frame to be used for showing to user the process that handset program changes.Key frame comprises stabilizer frame, current frame image when namely moving to static, and changing frame, namely from the current frame image of static firm motion.
The concrete computation process of calculation stability frame as shown in Figure 3.
First program needs setting threshold value n, when n two field picture does not change, can think that image is steady state (SS).Such present image and rear n two field picture compare, and concrete comparative approach can utilize frames differencing method.When image does not all change, stabilizer frame can be defined as.
Calculate the concrete computation process of changing frame as shown in Figure 4.
First program needs setting threshold value m, when present image changes compared with front m two field picture, then can think that this frame also exists change.Such present image and front m two field picture compare, and concrete comparative approach can utilize frames differencing method.When image exists change, candidate change frame can be entered.Whether the method for recycling connected domain determines whether noise, if not noise, then change between m image before judging, if not change, be then all stationary state before illustrating, such present image is then changing frame.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
