Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, data collecting system processing method of the invention, comprises the following steps：
S1, the first chip 2 and the second chip 3 gather the frame data of user；
The data collecting system of the present invention is spliced by the chip of two partial arrays, gathers the letter of user simultaneously when in use
Cease information.Face battle array due to being spliced is more applicable for the finger shape of user so that gather information while add area
Information is more complete, accurate.
S2, the described image data collected are sent to processing unit；
In data collecting system, provided with a processing unit, the processing unit is specifically as follows the partial array of MCU, i.e., two
Chip simultaneously be connected with a MCU.The MCU uses large area array algorithm, i.e. feature based value-based algorithm so that data collecting system
When handling view data, amount of calculation is less, while number of times of the user in typing information is less.
S3, processing unit handle the view data that two chips are collected successively, including：
S31, as shown in figure 4, the distance between first chip 2 and described second chip 3 are set into blank spot, the processing
Unit handles the first chip 2, blank spot, the view data of the second chip 3 successively, and the view data after processing is spliced
Processing, to form frame.
Because the chip in the data collecting system of the present invention is to be spelled to form by the data acquisition chip of two partial arrays,
In technique, a micron-sized gap is had between two chips, as shown in figure 3, between i.e. the first chip 2 and the second chip 3
Apart from D.In processing unit processes view data, the view data of the first chip 2 collection is handled first, two cores are then handled
Blank parts between piece, finally reprocess the view data of the second chip 3 collection.
In a specific embodiment, the distance between first chip 2 and described second chip 3 are set to blank spot,
Including：
The area of blank spot is equal with the pixel point areas on the first chip 2 and the second chip 3, the columns of the blank spot and institute
The columns for stating pixel is equal, the line number of the blank spot and the distance between first chip 2 and second chip 3 phase
Close.
As shown in Figure 3, Figure 4, data collecting system processing method of the present invention is by between the first chip 2 and the second chip 3
Distance is divided into the blank spot equal with pixel point areas, so that processor is recognized in the blank between handling two chips
Pickup area for pixel, the i.e. data collecting system is corresponded to respectively：The pickup area of first chip 2, second chip 3
Blank parts between pickup area, and the first chip 2 and the second chip 3.
Specifically, in one embodiment, when the distance between first chip 2 and second chip 3 are the pictures
During the integral multiple of the vegetarian refreshments length of side, the distance between first chip 2 and described second chip 3 are processed into by the processing unit
The blank spot equal with the pixel point areas, the processing unit handles the first chip 2, blank spot, second chip 3 successively
View data, to form frame.As shown in figure 4, the length of side of pixel is set as d, as D=N*d, i.e., when between two chips
When blank parts can just be filled by more several blank spots, then processor is directly with the first chip 2, blank parts, the second core
The order of piece 3 reads, handles view data respectively.
In another embodiment, when the distance between first chip 2 and second chip 3 are more than the pixel
During the integral multiple of the length of side, then keep the line number of the blank spot equal with the multiple, and increase the width per line blank point, will
The distance between first chip 2 and second chip 3 are divided into the integral multiple of the pixel length of side, the processing unit
The first chip 2, blank spot, the view data of the second chip 3 are handled successively, to form frame.As D=N*d+ △, △<D,
I.e. when the distance between two chips and the indivisible pixel length of side, then it is N rows by △ points, so, the blank spot of every row is increased
Plus △/N width, you can reduce blank parts due to the error brought.
Specifically, keep the line number of the blank spot equal with the multiple, and the width of the often capable blank spot of increase,
Including：
When the distance between first chip 2 and second chip 3 are more than the integral multiple of the pixel length of side, by this
Part more than the pixel length of side integral multiple is equally divided into blank spot line number part, so that first chip 2 and described the
The distance between two chips 3 are treated as being similar to the blank spot of the pixel.That is, △ is divided into N rows, so that each
Blank spot area is suitable.
S4, by after processing view data carry out splicing；
When carrying out splicing, the top half of frame and the latter half can form complete frame, two cores
The part that can not be read between piece is denoted as blank parts.
S5, repetition S1 ~ S4, until forming complete frame.
The repeat step includes：User constantly moves the collection of finger and first chip 2 and second chip 3
The relative position in area, so that first chip 2 and second chip 3 collect complete frame data.Due to two
The blank parts that individual chip is spliced to form, in log-on message, only need to repeatedly move finger, you can read chip for the first time
The part that can not be read, to form complete frame.
The present invention also provides a kind of data collecting system, as shown in Figure 2 and Figure 3, including the be arranged on same substrate 1
One chip 2 and the second chip 3, first chip 2 and second chip 3 are connected to processor, and both are gathered
To view data be sent to processor and handled.
In certain embodiments, processor also includes concatenation unit, for the view data after processing to be spliced, to be formed
Frame.
It should be appreciated that these are only the preferred embodiments of the present invention, it is impossible to therefore the scope of the claims of the limitation present invention,
Equivalent structure or equivalent flow conversion that every utilization description of the invention and accompanying drawing content are made, or be directly or indirectly used in
Other related technical fields, are included within the scope of the present invention.
