The following is a description of the detection system of the image capturing device disclosed in the present invention. Please refer to FIG. 1 and FIG. 1 is a block diagram of a detection system of the image capturing device of the present invention.

The detection system of the image capture device disclosed in the present invention, the detection system is used for detection in a production line, and the detection system is used for detecting an image capture device embedded in the test device, comprising: a connection module 11, The capture module 12, the decoding module 13, the verification module 14, and the recording module 15 are controlled.

The above test device is, for example, a notebook computer, a smart phone, a general type mobile phone, etc., and the test device is placed on a production line, and the production line is similar to a transport device, and the test device placed on the production line is moved to move. And when the test device is driven by the production line to enter the black screen space with a fixed light source (to avoid the interference of the image capturing device of the test device by external light, which helps to reduce the image) The capture device captures the external interference factor of the decoded image and causes the decoded image to be misjudged and then locates it. The connection module 11 of the detection system establishes a connection with the test device, and the connection mode of the detection system The group 11 establishes a connection with the test device in a wired manner or in a wireless manner. The wired method includes: a connection line, a network route, etc., and the wired method includes: a wireless network, a Bluetooth, a WI-FI, etc. It is merely illustrative and is not intended to limit the scope of application of the invention.

After the connection module 11 is connected to the test device, the image capture device of the test device is controlled by the control capture module 12, that is, the control capture module 12 turns on the test device. The image capturing device controls the image capturing device of the testing device to capture the image of the external two-dimensional barcode to generate the decoded image, and the image capturing device of the testing device captures the image of the external two-dimensional barcode to generate The image is decoded, and the connection module 11 obtains the device information and the decoded image from the test device.

The above device information is, for example, the MAC value of the test device (the MAC value is a unique and non-repeating value) or a unique and non-repeating set value (which is a defined value), and the device information is used to determine the unique one. For the purpose of the test device, the above description of the device information is merely illustrative and is not intended to limit the scope of application of the present invention.

After the connection module 11 obtains the decoded image from the test device, the decoding module 13 decodes the two-dimensional barcode in the decoded image according to the two-dimensional barcode decoding rule. The code is used to decode the decoded information, and is defined in the two-dimensional barcode decoding rule. When the non-complete two-dimensional barcode is used, the decoding of the two-dimensional barcode is not performed, and the complete two-dimensional barcode has three complete barcodes. The locating point or the complete starting bar code and the terminating bar code are used as the judgment conditions, which are merely exemplified herein, and are not intended to limit the application scope of the present invention.

At this time, the verification module 14 can compare the decoded information to "XYZ456" and the standard information to "ABC123". "No phase with.

When the decoding information cannot be verified by the verification module 14 , the recording module 15 records the device information, thereby knowing that the decoded image captured by the image capturing device of the testing device is incorrect, that is, There are problems with the image capturing device of the testing device, such as lens contamination of the image capturing device, wafer damage of the image capturing device, and failure of the autofocus function of the image capturing device.

In addition, in addition to storing decoded information, the 2D barcode can store level information. For example, in the case of the 2D barcode "PDF417", the 2D barcode "PDF417" is divided into 0 to 8 There are 9 levels, and the higher the level, the stronger the debugging ability, which can be further placed on a series of different levels of 2D barcodes for testing the level of the image capture device.

That is, after the two-dimensional barcode captured by the image capturing device is decoded by the decoding module 13, the decoding information is decoded as "ABC123" and the level information is "4", the decoding information is "ABC123", and the level information is "5", the decoding information is "ABC123" and the level information is "6". At this time, the decoding information is "ABC123" and the verification is verified by the verification module 14. At this time, since the level information is more than one, the recording mode is The group 15 records with the highest level information, that is, the recording module 15 records the device information and the level information is "6" to determine the level of the image capturing device of the testing device is "6".

Then, the verification module 14 performs the comparison verification on the decoding information “XYZ456”, that is, the comparison information of the decoding information “XYZ456” and the standard information corresponding to the external two-dimensional barcode is “ABC123” (step 150). The verification module 14 can compare the decoding information to "XYZ456" and the standard information to "ABC123", and the decoding information to "XYZ456" cannot be verified by the verification module 14.

Then, since the decoding information is "XYZ456" and cannot be verified by the verification module 14, the recording module 15 records the device information as "00-11-D8-9C-DC-4B" (step 160). That is, it can be known that the decoded image captured by the image capturing device of the testing device 21 is incorrect, that is, the image capturing device of the testing device 21 has a problem, for example, the lens of the image capturing device is dirty, The wafer of the image capture device is damaged, the autofocus function of the image capture device is disabled, and the like.
