Detailed Description
The following is further detailed by the specific embodiments:
example 1
The embodiment of the turntable-based camera module burning system is basically as shown in the attached figure 1, and comprises the following components:
the preset module is used for presetting an identification code for recording the identification information of the camera module;
the binding module is used for binding the corresponding data of the camera module with the identification code;
the scanning module is used for scanning the identification code on the camera module;
the analysis module is used for analyzing the identification code information to obtain the identity data in the identification code information;
the generating module is used for generating a target characteristic data table according to the configuration information of the intelligent terminal;
and the burning module is used for matching the identity data with the target characteristic data table and burning the identity data and the data bound with the identification code to a memory of the intelligent terminal in batches.
Firstly, the preset module presets an identification code for recording identification information of the camera module.
In this embodiment, the identification code is a two-dimensional code. The two-dimensional code (2-dimensional bar code) is a pattern which is distributed on a two-dimensional plane according to a certain rule by using a certain specific geometric figure, is black and white and is alternated and records data symbol information. The concept of 0 and 1 bit stream forming the internal logic base of computer is used ingeniously in coding, several geometric forms correspondent to binary system are used to represent literal numerical information, and the information can be automatically read by means of image input equipment or photoelectric scanning equipment so as to implement automatic information processing. Adopt radium carving technique, also laser marking, perhaps printing ink spraying, print the two-dimensional code on the camera module surface, the two-dimensional code has contained the identification information of camera module, information such as firm, product model, product serial number.
Then, the binding module binds the corresponding data of the camera module with the identification code.
Generally, a camera module manufacturer has a special database for storing data to be recorded for different camera modules, such as focusing parameters, lens shading correction parameters, white balance parameters, and the like. After the two-dimensional code is preset on the camera group module, data corresponding to the camera module are found out from the database, and the data and the two-dimensional code are bound. Specifically, a scanning device needs to be prepared, the scanning device is connected with a computer, and after the scanning device scans the two-dimensional code, the computer is connected with a database, so that the two-dimensional code and the data of the corresponding camera module are bound.
Then, the scanning module scans the identification code on the camera module.
After the camera module leaves the factory, the camera module can be assembled by an intelligent terminal manufacturer and assembled on an intelligent terminal, such as a smart phone and a tablet computer. In this embodiment, the manufacturer of the intelligent terminal has obtained the database from the manufacturer of the camera module in advance, and the database contains the data applied to the camera module and the two-dimensional code bound with the data, and in the assembling process, the two-dimensional code on the camera module is scanned, so that the identification information of the camera module can be obtained.
And then, the analysis module analyzes the identification code information to obtain the identity data in the identification code information.
And after the two-dimensional code is scanned, analyzing the two-dimensional code to acquire data information in the two-dimensional code. Specifically, the data information in the two-dimensional code is analyzed into a data packet containing each identity data, and each identity data in the data packet can be analyzed in the subsequent process. In this embodiment, for the identity data information, since the field is relatively large, the identity data information is stored in a BLOB format.
And then, the generating module generates a target characteristic data table according to the configuration information of the intelligent terminal.
In the process of burning the characteristic data, the configuration information of the current terminal to be burned can be obtained, the configuration information comprises all the characteristic data which need to be copied and are not burned in the burning state of the intelligent terminal, and all the characteristic data which need to be copied and are not burned in the burning state are combined to generate a characteristic data information table with a burning target of the terminal to be burned. Specifically, the parameter value of the characteristic data option is used for representing the identification information of the burning state, such as a serial number SN, and the parameter value is 0x00 and represents that the writing is not carried out; the parameter value is 0x01, which represents that the transcription has been carried out; the parameter value is 0xFF, which represents that the model is not suitable for the machine type; the terminal can determine whether the data needs to be copied or not through the characteristic data parameter value
And finally, the burning module matches the identity data with the target characteristic data table and burns the identity data and the data bound with the identification code to a memory of the intelligent terminal in batches.
In this embodiment, the burning module includes a determining unit, an obtaining unit, an executing unit and a display unit, and the burning data includes a focusing parameter, a lens shading correction parameter and a white balance parameter. Firstly, the judging unit judges whether the intelligent terminal needs to burn identity data according to the target characteristic data table. If the intelligent terminal needs to burn the identity data, the acquisition unit acquires and verifies the data packet in the analyzed identification code information according to the check code so as to determine whether the item information in the data packet matches the item information corresponding to the target characteristic data table of the intelligent terminal. Finally, if the item information in the data packet is matched, the execution unit acquires and records the identity data to a corresponding storage position of the intelligent terminal; the display unit sets the burning state of the burnt target characteristic data as burnt and displays the burning result.
Specifically, when the identity data is burned to the corresponding storage position of the intelligent terminal, a batch burning mode is adopted. For example, the identity data is 600MB, 10 minutes are required for one-time burning, the identity data is divided into 10 shares, each share is 60MB, and then burning is performed. That is, during one-time burning, the identity data burned once is 600MB, and after the identity data is divided into 10 parts, the identity data burned once is 60MB, and the time of one-time burning is 1 minute. Therefore, the difficulty of data reading, transmission and storage is reduced, and the crash can be prevented.
In addition, the execution unit comprises three subunits, and when the item information in the data packet is matched, the first subunit acquires the burning state of each target characteristic data in the target characteristic data table of the intelligent terminal. If the burning state of the target characteristic data is not burning, the second subunit acquires and burns identity data to a corresponding storage position of the intelligent terminal; if the burning state of the target characteristic data is burnt, the third subunit does not burn the target characteristic data.
Specifically, whether the intelligent terminal needs to burn identity data or not is judged, that is, whether the characteristic data information of the intelligent terminal is completely burned or not is detected, and when the characteristic data information of the intelligent terminal is completely burned, burning is completed. Otherwise, when the intelligent terminal is not completely burned, the data packet in the identification code information is verified according to the check code prestored in the terminal to be burned, and the item information in the data packet is obtained, wherein the item information comprises the model item name, the content and the like corresponding to the intelligent terminal. If the item information in the data packet is consistent with the item information corresponding to the intelligent terminal target characteristic data information table, performing burning operation; if the data is inconsistent with the data, the burning is finished, and the burning result is finally displayed.
Example 2
The difference from the embodiment 1 is that the test device further comprises a debugging module and a testing module, wherein the debugging module is used for debugging the camera module by using different data and determining data suitable for the camera module; the test module is used for controlling the camera module to shoot pictures and judging whether the function of the camera module is normal or not.
Because the optical performance and the image processing circuit of different camera modules are different, different data are needed to be matched for use. In this embodiment, debug the camera module, find out the best data, can specifically refer to prior art to realize the optimal shooting effect. After the camera module is installed in the intelligent terminal, the intelligent terminal is used for photographing, and whether parameters such as imaging, color and AF focusing of the camera module meet functional requirements or not is checked. Specifically, it is checked whether the imaged pixel reaches a design value, for example, a pixel specification of 1000 × 800, whether a color pixel value of 255 is satisfied, whether a touch autofocus or phase focusing function can be realized.
When data are burned to the intelligent terminals, the two-dimension code generating equipment dynamically and orderly generates different two-dimension codes according to regular characteristic data information packets needing to be burned to different intelligent terminals, and a two-dimension code generating device is arranged to dynamically display the different two-dimension codes according to preset burning time of the terminals to be burned. For example, when the nth intelligent terminal of the production line reaches the copying station, the two-dimensional code generating device displays the generated two-dimensional code corresponding to the nth intelligent terminal for scanning by the scanning device on the tape recording terminal, and the display period of the nth intelligent terminal corresponding to the two-dimensional code and the preset recording time of the terminal to be recorded are the station generating time. When the time of the station corresponding to the Nth intelligent terminal is finished, the two-dimensional code generating device is switched to the two-dimensional code corresponding to the (N + 1) th intelligent terminal so that the (N + 1) th to-be-burned terminal can scan the two-dimensional code.
And before the identification code information corresponding to the intelligent terminal is detected, detecting whether the intelligent terminal is in a debugging mode. If the intelligence is not in the debugging mode, the intelligent terminal prompts that the burning fails; on the contrary, if the intelligent terminal is in the debugging mode, when the scanning device corresponding to the intelligent terminal detects the two-dimensional code, scanning and identifying the two-dimensional code information, wherein the two-dimensional code information comprises each identity data to be burned of the current intelligent terminal.

The camera collects the picture of the position of the camera module on the rotating platform, the picture is sent to the picture identification module after collection is finished, and after the picture collected by the camera is received, the picture is identified, and whether black clusters appear in the picture is judged. The black group is also the black part of lacquer in the picture, and this black part of lacquer is because the skew has appeared in the position that the camera module was placed on the revolving stage for the camera module has blocked partial light, thereby the shade that appears.
If appear black group in the picture, show that the skew has appeared in the position that the camera module was placed on the revolving stage, need carry out light compensation, remove the position of camera module simultaneously. When black clusters appear in the picture, the singlechip controls to switch on a power switch of the LED lamp, and light compensation is carried out on the camera module through the light of the LED lamp; and the LED lamp is controlled to illuminate in a half-power state and then in a full-power state, so that the service life of the LED lamp is prolonged. Meanwhile, because the camera module deviates from the station on the rotating table, the photosensitive sensor is exposed, the light of the LED lamp irradiates on the photosensitive sensor, the photosensitive sensor receives the light and sends a signal to the controller, and the controller controls the cylinder to push the camera module to move until the camera module blocks the photosensitive sensor, namely the camera module recovers to the normal station.
