FIG. 1 is a system structure block diagram of an embodiment of a camera module programming system based on a turntable of the present invention.

Detailed ways

The following is a further detailed description through specific embodiments:

Example 1

The embodiment of the camera module burning system based on the turntable of the present invention is basically as shown in FIG. 1, including:

The preset module is used to preset the identification code for recording its identification information on the camera module;

The binding module is used to bind the corresponding data of the camera module with the identification code;

Scanning module, used to scan the identification code on the camera module;

The parsing module is used to parse the identification code information and obtain the identity data in the identification code information;

A generation module is used to generate a target feature data table according to the configuration information of the intelligent terminal;

The burning module is used to match the identity data with the target feature data table, and burn the identity data and the data bound with the identification code to the memory of the smart terminal in batches.

First, the preset module presets an identification code for recording its identification information on the camera module.

In this embodiment, the identification code is a two-dimensional code. 2-dimensional bar code (2-dimensional bar code) is a graphic that records data symbol information in black and white and is distributed on a two-dimensional plane with a certain geometric figure according to a certain rule. In coding, the concept of "0" and "1" bit stream that constitute the internal logic basis of the computer is cleverly used, and several geometric shapes corresponding to binary are used to represent text and numerical information. Automatic reading to realize automatic information processing, has the advantages of high-density coding, large information capacity, wide coding range, strong fault tolerance, low cost, and easy production. Using laser engraving technology, that is, laser marking, or ink spraying, the two-dimensional code is printed on the surface of the camera module. The two-dimensional code contains the identification information of the camera module, such as the manufacturer, product model, product serial number, etc. .

Then, the binding module binds the corresponding data of the camera module with the identification code.

Usually, camera module manufacturers will have a special database to store the data that different camera modules need to burn, such as focusing parameters, lens shadow correction parameters, white balance parameters, etc. After presetting the QR code on the camera module, find out the data corresponding to the camera module from the database, and bind the data with the QR code. Specifically, a scanning device needs to be prepared, which is connected to the computer. After the scanning device scans the QR code, the computer is connected to the database, so that the QR code is bound to the data of the corresponding camera module. Certainly.

Then, the scanning module scans the identification code on the camera module.

After the camera module leaves the factory, it will be assembled in the smart terminal manufacturer and assembled on the smart terminal, such as smart phone and tablet computer. In this embodiment, the manufacturer of the smart terminal has obtained a database from the manufacturer of the camera module in advance, and the database contains the data applied to the camera module and the QR code bound to the data. During the assembly process, scan the camera module The identification information of the camera module can be obtained by clicking the QR code on the module.

Next, the parsing module parses the identification code information to obtain the identity data in the identification code information.

After scanning the QR code, parse the QR code to obtain the data information in the QR code. Specifically, the data information in the two-dimensional code is parsed into data packets containing various identity data, and each identity data in the data packets can also be parsed out in the subsequent process. In this embodiment, the identity data information is stored in the form of BLOB because the field is relatively large.

Next, the generating module generates a target feature data table according to the configuration information of the smart terminal.

In the process of programming the feature data, the configuration information of the terminal to be programmed can be obtained. The configuration information includes the feature data that needs to be transcribed by the smart terminal, but the programming status is not yet programmed. The combination of each feature data to be programmed generates an information table with programming target feature data of the terminal to be programmed. Specifically, the parameter value of the feature data option is used to represent the identification information of the programming state, such as serial number SN, the parameter value is 0x00, which means not copied; the parameter value is 0x01, which means it has been copied; the parameter value is 0xFF, which means this Not suitable for this model; the terminal can determine whether the data needs to be transcribed through the characteristic data parameter value

Finally, the burning module matches the identity data with the target feature data table, and burns the identity data and the data bound with the identification code to the memory of the smart terminal in batches.

In this embodiment, the programming module includes a determination unit, an acquisition unit, an execution unit, and a display unit, and the data to be programmed include focus parameters, lens shadow correction parameters, and white balance parameters. First, the judging unit judges whether the smart terminal needs to burn the identity data according to the target feature data table. If the smart terminal needs to burn the identity data, then the acquisition unit obtains and verifies the data packet in the parsed identification code information according to the check code to determine whether the item information in the data packet matches the item information corresponding to the target feature data table of the smart terminal . Finally, if the item information in the data package matches, the execution unit obtains and burns the identity data to the corresponding storage location of the intelligent terminal; the display unit sets the burning status of the target feature data after the burning has been completed, and displays the burning result .

Specifically, when programming the identity data to the storage location corresponding to the smart terminal, the method of batch programming is adopted. For example, if the identity data is 600MB, it takes 10 minutes to burn at one time. Divide the identity data into 10 copies, each with 60MB, and then burn them. That is to say, during one-time burning, the identity data for single burning is 600MB, and after dividing the identity data into 10 parts, the identity data for single burning is 60MB, and the single burning time is 1 minute . This reduces the difficulty of data reading, transmission, and storage, thereby preventing crashes.

In addition, the execution unit includes three subunits. When the item information in the data packet matches, the first subunit acquires the programming status of each target feature data in the target feature data table of the smart terminal. If the programming status of the target feature data is not programmed, the second subunit acquires and programs the identity data to the corresponding storage location of the smart terminal; if the programming status of the target feature data is programmed, the third subunit does not program target feature data.

Specifically, it is determined whether the smart terminal needs to be programmed with identity data, that is, it is detected whether all the feature data information of the smart terminal has been programmed. When all the feature data information of the smart terminal has been programmed, the programming is completed. On the contrary, when the smart terminal has not been programmed completely, according to the check code pre-stored in the terminal to be programmed, the data packet in the identification code information is checked, and the item information in the data packet is obtained. Model item name, content, etc. If the item information in the data package is consistent with the item information corresponding to the target feature data information table of the intelligent terminal, the burning operation is performed; if it is inconsistent, the burning is ended, and the burning result is finally displayed.

Example 2

The only difference from Embodiment 1 is that it also includes a debugging module and a testing module, wherein the debugging module is used to debug the camera module using different data, and determine the data applicable to the camera module; the testing module is used to control the camera module. The module takes pictures and judges whether the function of the camera module is normal.

Due to the different optical properties and image processing circuits of different camera modules, different data are required for matching and use. In this embodiment, the camera module is debugged to find out the best data, and the specific reference can be made to the prior art, so as to achieve the best shooting effect. After the camera module is installed in the smart terminal, use the smart terminal to take pictures to check whether the imaging, color, AF focus and other parameters of the camera module meet the functional requirements. Specifically, it is checked whether the imaged pixels reach the design value, such as the pixel specification of 1000*800, whether it meets the color pixel value of 255, and whether the touch auto focus or phase focus function can be realized.

When programming data to the smart terminal, the two-dimensional code generation device dynamically and orderly generates different two-dimensional codes from the regular feature data packets that need to be programmed to different smart terminals, and sets the two-dimensional code generation device according to the required data. The preset programming time of the programming terminal dynamically displays different QR codes. For example, when the Nth smart terminal of the assembly line reaches the copying station, the two-dimensional code generating device displays the generated two-dimensional code corresponding to the Nth smart terminal for scanning by the scanning device on the terminal with the recording device. The Nth smart terminal corresponds to the display period of the QR code and the preset programming time of the terminal to be programmed, that is, the station time is generated. When the time for the station corresponding to the Nth smart terminal is completed, the two-dimensional code generating device switches to the two-dimensional code corresponding to the N+1th smart terminal for scanning by the N+1th terminal to be programmed.

Before detecting the identification code information corresponding to the smart terminal, it is detected whether the smart terminal is in the debugging mode. If the smart terminal is not in the debugging mode, the smart terminal will prompt that the programming failed; on the contrary, if the smart terminal is in the debugging mode, when the scanning device corresponding to the smart terminal detects the QR code, it will scan and identify the QR code information. The QR code information includes the current Each identity data to be programmed by the smart terminal.

Example 3

Compared with Embodiment 2, the only difference is that it also includes a picture collection mechanism, a picture recognition module, a control module, an illumination mechanism and an adjustment mechanism. Before burning the camera module, perform light compensation and adjust the position of the camera module on the turntable according to the actual situation to ensure that the camera module does not deviate from its working position. Meanwhile, this embodiment is implemented based on the existing turntable mechanism, that is, the multi-station mobile phone camera module detection machine disclosed in the document CN205377994U.

Specifically, the position of the camera module on the rotary table is located in the radial direction of the rotary table, the camera module is placed on the position of the rotary table with a photosensitive sensor, and the camera module is placed on the photosensitive sensor. If the position of the camera module on the rotary table does not deviate from its position, that is, when it is in the normal position, the camera module will just press and block the photosensitive sensor; on the contrary, if the position of the camera module on the rotary table deviates from its position station, the photosensitive sensor will be exposed.

The picture collection mechanism includes a camera and a bracket, the camera is fixed on the bracket, the bracket is welded on the turntable, and the camera is located directly above the camera module; the lighting mechanism includes an LED light and a light stand, the LED light is fixed on the light stand, and the light stand is welded On the turntable, the LED light is located just above the camera module; the image recognition module is specifically image recognition software, the control module is a single-chip microcomputer, and the adjustment mechanism includes a controller and two air cylinders, the two air cylinders are located in the circumferential direction of the turntable, and They are located on both sides of the camera module.

The camera collects the picture of the position where the camera module is placed on the turntable. After the picture is collected, it is sent to the picture recognition module. After receiving the picture collected by the camera, the picture is recognized and it is judged whether there are black groups in the picture. The black group is also the dark part of the picture. This dark part is due to the offset of the position of the camera module placed on the rotating table, which makes the camera module block part of the light, resulting in shadows.

If there is a black group in the picture, it means that the position of the camera module placed on the rotary table has shifted, and it is necessary to perform light compensation and move the position of the camera module at the same time. When a black group appears in the picture, the single-chip microcomputer controls the power switch of the LED light, and compensates the light of the camera module through the light of the LED light; and controls the LED light to illuminate at half power first, and then at full power. Lighting is carried out, thereby increasing the life of LED lamps. At the same time, because the position of the camera module on the rotary table deviates from its working position, the photosensitive sensor is exposed, and the light of the LED light shines on the photosensitive sensor. After the photosensitive sensor receives the light, it sends a signal to the controller, and the controller controls the cylinder. Push the camera module to move until the camera module blocks the photosensitive sensor, that is, the camera module returns to the normal working position.
