[0043] Figure 2 4 is a flow chart of a method for color calibration of a fisheye lens shown in an embodiment of the present application.

[0044] See also Figure 2 , a color calibration method for a fisheye lens, comprising:

[0045] Step S101, multiple fisheye lenses are connected to the connector of the test board through a connecting harness, and a power supply unit energizes the multiple fisheye lenses through the connector and the connecting harness, so that each fisheye lens is in a powered-on state.

[0046] It should be noted that multiple fisheye lenses are connected to the connector of the test board through a connecting harness, and the power supply unit will be connected to an external 12V power supply to power each fisheye lens.

[0047] Step S102: Place each fisheye lens into a groove of a loading fixture so that each fisheye lens can cover the light source.

[0048] Step S103: the main control unit sends a lighting instruction to each fisheye lens, so that each fisheye lens outputs image information, and the image information is sent to the smart terminal through the main control unit.

[0049] It should be noted that the main control unit will light up each fisheye lens sent to the object-carrying fixture so that each fisheye lens outputs image information.

[0050] Step S104: the intelligent terminal calculates and processes the image information and the preset image information, outputs correction data, and sends the correction data to the main control unit, which then sends the correction data to each fisheye lens through a connector and a connecting harness.

[0051] It should be noted that the intelligent terminal will calculate and process the multiple image information and the preset image information one by one, output the correction data of each image information, and then send each correction data to each fisheye lens through the main control unit.

[0052] Step S105: Each fisheye lens writes the correction data to complete the correction process.

[0053] It should be noted that each fisheye lens writes the correction data to perform the correction work.

[0054] Figure 3 for Figure 2 In a more detailed embodiment, a color calibration method for a fisheye lens includes:

[0055] Step S201: multiple fisheye lenses are connected to the connector of the test board through a connecting harness, and a power supply unit energizes the multiple fisheye lenses through the connector and the connecting harness, so that each fisheye lens is in a powered-on state.

[0056] The description here can refer to step S101, which will not be repeated here.

[0057] Step S202: Place each fisheye lens into a groove of a loading fixture so that each fisheye lens can cover the light source.

[0058] The description here can refer to step S102, which will not be repeated here.

[0059] Step S203: The main control unit sends a lighting instruction to each fisheye lens, so that each fisheye lens outputs image information, and the image information is sent to the smart terminal through the main control unit.

[0060] The description here can refer to step S103, which will not be repeated here.

[0061] Step S204, extracting the first color layer, the second color layer and the third color layer of the image information, comparing the first color layer with the preset first color layer in the preset image information, and outputting a first deviation threshold; compensating the first deviation threshold, and outputting a first compensation data packet; comparing the second color layer with the preset second color layer in the preset image information, and outputting a second deviation threshold; compensating the second deviation threshold, and outputting a second compensation data packet; comparing the third color layer with the preset third color layer in the preset image information, and outputting a third deviation threshold; compensating the third deviation threshold, and outputting a third compensation data packet; merging the first compensation data packet, the second compensation data packet and the third compensation data packet, and outputting correction data;

[0062] The correction data is sent to the main control unit, and then sent to each fisheye lens through the connector and the connecting harness.

[0063] It should be noted that the first color layer is generally a red layer, the second color layer is generally a green layer, and the third color layer is generally a blue layer. The intelligent terminal first extracts the three colors of the image information sent by the fisheye lens, and then extracts and compares the three colors of the preset image information, and then outputs the deviation thresholds of the three color layers. Finally, compensation is performed according to the deviation thresholds of the three color layers to meet the preset requirements. Specifically, the compensation here can comprehensively consider the three color layers, that is, when the brightness or saturation of the first color layer is large, the brightness or saturation of the second color layer and the third color layer can be appropriately enhanced for comprehensiveness. Further, the first compensation data packet, the second compensation data packet and the third compensation data packet will be further analyzed and processed to output the correction data. Finally, the correction data is sent to the main control unit, which is sent to each fisheye lens by the main control unit through a connector and a connecting harness.

[0064] Step S205: After each fisheye lens writes the correction data into its internal memory, the correction data is called to complete the correction process.

[0065] It should be noted that the internal memory is an EEPROM memory. When the fisheye lens needs to be calibrated, the calibration can be completed by simply calling the calibration data. At the same time, the internal memory also has a storage function.
