Specific embodiment
The present general inventive concept is video record to be carried out by the browser interface to webpage loading complete process, to institute
It states video data and carries out framing, multiple framing images and its corresponding recording time are obtained, according in the multiple framing image
The image state variation in specified region, determines the load time of corresponding region in the webpage, to realize accurate measurement webpage
Load time realizes the purpose of accurate measurement web page loading time.
The measurement method and device of a kind of web page loading time of the embodiment of the present invention are retouched in detail with reference to the accompanying drawing
It states.
Fig. 1 shows the flow chart of the measurement method of the web page loading time of the embodiment of the present invention.
Referring to Fig.1, in step S110, it is retrieved as the video of the predetermined time length of the browser interface recording of load webpage
Data.
An exemplary embodiment of the present invention can be in the video data that step S110 is obtained through third party's screen
Curtain video recording software or the first-class mode of high-speed camera are recorded, and the predetermined time length is greater than or equal to the time of webpage load.
In step S120, framing is carried out to the video data got in step S110, obtain multiple framing images and its
Corresponding recording time.In general, video data all includes the metadata of the projects such as recording time, size of data, it can be according to described
The time offset value of metadata and the multiple framing image obtains its corresponding recording time, or directly by the multiple point
The time offset value of frame image is as its recording time.
Respective area in webpage is determined according to specifying the image state in region to change in multiple framing images in step S130
The load time in domain.Wherein, the specified region in the multiple framing image is corresponding to the web page area of load time to be measured,
It can such as, but not limited to, the specified region is marked by third party's toolmark tool or marks the specified region manually
Deng for example, the coordinates regional [0,0,200,300] in the specified region of mark indicates that starting point coordinate is [0,0] and area size is
[200,300].
Specifically, step S130 can include:
End-state calibration: the final of specified region is calculated based on the framing image recorded the latest in multiple framing images
Image state；
Positioning is completed in load: being determined in the multiple framing image, the image shape in the specified region recorded earliest
State framing image identical with the final image state；
Load time calculates: the recording time for loading the framing image of initial time and the determination based on webpage calculates institute
State the load time of corresponding region in webpage.Here it is possible to by the record of the first framing image in the multiple framing image
Time processed is that the webpage loads initial time, also provides the webpage by user and loads initial time.
Positioning is completed in order to carry out the end-state calibration and load, needs to calculate the framing image recorded the latest
Described in specify the image state (i.e. final image state) in region, and need to divide the multiple framing image frame by frame
Analysis calculates the image state for specifying region described in each framing image, then will specify area described in each framing image
The image state in domain is compared with the final image state, and determines the image shape in the specified region recorded earliest
State framing image identical with the final image state.
An exemplary embodiment of the present invention is demarcated and is loaded in the processing for completing positioning in end-state, to locating
Any framing image of reason can calculate the image state in the specified region in the framing image by following operation:
Firstly, by identical piece of size that the specified region division of the framing image is predetermined number.For example, will
The specified region division is M*N block, i.e. M row N is arranged, each block size is identical.
Then, computation partition at each of piece status data being filled, and block according to the predetermined number is filled out
The status data filled calculates the filling rate in the specified region.
It is provided below to be used to calculate three embodiments that the filling rate in region is specified described in framing image:
Embodiment one
The computation partition at each of piece status data being filled, and block according to the predetermined number is filled
Status data calculate the filling rate in the specified region and include:
Firstly, whether including that non-empty white pixel determines whether block is non-blank-white block according to described each piece.
For example, can determine in the block if thering is any pixel to meet the following conditions in a block comprising non-empty white pixel:
| R-G | > constant C1And | R-B | > constant C2And | G-B | > constant C3, or
R < constant C4And R < constant C5And B < constant C6,
Wherein, described R, G and B are respectively the red, green, blue color component value of the pixel, C1~C6For constant.
It can determine whether there is non-empty white pixel in described piece by above formula.If there is non-empty white pixel, then described piece is non-
Blank block；If there is no non-empty white pixel in described piece, determine that each piece is blank block.
After determining whether each piece be non-blank-white block, it may be determined that the number of non-blank-white block in the specified region.
Later, first filling rate in the specified region can be calculated according to the following formula:
The number of block in region is specified described in first filling rate=non-blank-white block number ÷.

Mean value obtains block complexity, i.e., calculates described piece of complexity by following equation:
In block complexity=block in the sum of complexity of all pixels point ÷ block pixel number.
For example, if be calculated in a certain piece the sum of complexity of all pixels point be 23, and in block pixel
Number is 100, then it is 0.23 that block complexity, which is calculated,.
Finally, averaging to all pieces in the specified region of block complexity, the second of the specified region is obtained
Filling rate.That is, calculating second filling rate in the specified region according to the following formula:
In second filling rate=region in the region the sum of all pieces of complexities ÷ block sum.
For example, being the identical 100 block A of size by the specified region division1, A2, A3... ... A100, by calculating
Complexity to each piece is respectively a1, a2, a3……a100, acquire the second filling rate=(a in the specified region1+a2+a3
+……+a100)÷100。
