Detailed Description

In the various figures of the present application, features that are structurally identical or functionally similar are denoted by the same reference numerals.

Fig. 1 schematically illustrates an automotive interior and exterior trim appearance color difference detection system 100 according to one embodiment of the present application. The system 100 includes a color difference detection device 200, a camera 300, a pedal trigger device 400, and a computer 500. The color difference detecting apparatus 200 may be any commercially available color difference detecting instrument of any suitable brand, and may be a portable color difference detecting instrument. The video camera 300 may be, for example, an industrial camera. The video camera 300 may be any image capturing device that satisfies the pixel requirement, including but not limited to a digital camera, a mobile phone camera, or even a camera carried by the computer 500. The pedal trigger 400 may include a base 410 and a plurality of pedal switches 420 (e.g., two pedal switches in fig. 1) disposed on the base. Each pedal switch 420 may include a pedal, a microswitch, and a reset device disposed between the pedal and the microswitch. When the pedal of the pedal switch 420 is pressed by foot or reset after being released, the microswitch can realize the switching or on-off of the circuit associated with the microswitch, thereby realizing the purpose of operation switching. For example, an electrical circuit may be built into the pedal trigger 400 to issue control commands.

The computer 500 may be any suitable electronic data processing device such as a desktop computer, a laptop computer, or the like. In the system 100 of the present application, the color difference detecting device 200, the camera 300 and the pedal trigger device 400 are in data communication with the computer 500, for example, by wired or wireless communication. In the context of the present application, the term "data connection" means that the connection between these components ensures that data can be selectively transmitted therebetween, for example, the detection data acquired by the color difference detection apparatus 200, the image data captured by the camera 300, and the control data (command) issued by the pedal trigger apparatus 400 can be respectively transmitted to the computer 500 for processing, and the computer 500 or a module in the computer 500 can also issue a command for controlling the operation of the color difference detection apparatus 200 or the camera 300. In the wired data connection manner, USB interface devices may be respectively provided in the color difference detecting device 200, the camera 300, the pedal type triggering device 400, and the computer 500, and connected to each other using USB data lines.

In an alternative embodiment of the color difference detection system 100 for exterior and interior trim parts of a vehicle, as shown in fig. 2, the color difference detection device 200, the camera 300, the pedal type trigger device 400 and the computer 500 may be wirelessly connected to each other, in which case a wireless transmission module such as WIFI may be provided in each of the color difference detection device 200, the camera 300, the pedal type trigger device 400 and the computer 500. The color difference detecting device 200, the camera 300, the pedal type trigger device 400 and the computer 500 may be wirelessly data-connected to each other through a dedicated communication protocol, so that the color difference detecting device 200, the camera 300 and the pedal type trigger device 400 may transmit data and commands to the computer 500, respectively. Optionally, the vehicle interior and exterior trim color difference detection system 100 may be further configured with a wireless data exchange device 600 such as a wireless router. Thus, the color difference detection device 200, the camera 300, the pedal type trigger device 400 and the computer 500 can be in data connection with each other via the wireless data exchange device 600.

The pedal switch 420 of the pedal trigger device 400 is configured to be associated with a functional module in the computer 500. For example, in the case where the computer 500 is a desktop or laptop computer, the pedal switch 420 may be configured to map with one or more shortcut keys of the computer (e.g., one of the keys on the keyboard). In this application, the term "map" means that operating a pedal switch 420 causes a function module on a computer to be selected and operated accordingly, thereby performing the same function in the same manner as selecting and operating the function module using a mouse and a keyboard.

The computer 500 is provided with a color difference detection module 200a capable of operating the color difference detection apparatus 200 and an image pickup module 300a capable of operating the camera 300, respectively. A pedal trigger device 400 is operatively coupled to the modules so that they can be selectively activated and operated. Operatively coupling the pedal trigger device 400 to a module means that one or more pedal switches 420 of the pedal trigger device 400 are associated with the module, and operating the pedal switches 420 may accordingly cause the module to activate and operate the device corresponding to the module. Here, the operation of the pedal switch 420 includes, but is not limited to, pressing the pedal switch 420 one or more times. Pressing the pedal switch 420 different times within a given time period may be specified to activate different modules or correspond to different operational steps within the same activated module. For example, it may be prescribed that pressing the pedal switch 420 once in a time of 1 second activates only the color difference detection module 200a that can operate the color difference detection apparatus 200, while pressing the pedal switch 420 twice consecutively in a time of 1 second activates only the camera module 300a that can operate the video camera 300, and so on.

Although the color difference detecting system for the exterior and interior appearance of the automobile according to the present application is described above only in the manner of the step type triggering device 400, it should be clear that the present application should be limited only to such a step type triggering device. Other non-hand-operated triggering devices capable of avoiding hand operation of a user can also be adopted in the system for detecting the color difference of the exterior and interior trim appearance parts of the automobile. Another example of such a non-human hand operated trigger device is a voice activated trigger device, for example. In this case, the above-mentioned "mapping" may also mean that a specific voice command of a user may cause a certain function module on the computer to be selected and operated accordingly, thereby implementing the same function in the same manner as selecting and operating the function module using a mouse and a keyboard. Thus, anything described in this specification in relation to a pedal-type trigger device is equally applicable to a non-manually operated trigger device, such as a voice activated trigger device.

An embodiment of a method for detecting color difference of an exterior appearance using the color difference detection system 100 for interior and exterior appearances of an automobile will be described with reference to fig. 3. In this example of the method, although illustrated with a pedal-type trigger device, it will be clear to a person skilled in the art that similar method steps are equally applicable to other non-manually operated trigger devices, such as a voice-activated trigger device.

First, in step S20, if the color difference detection device 200, the camera 300, the pedal trigger device 400 and the computer 500 are respectively connected, the color difference detection module 200a provided in the computer 500 is activated, for example, the color difference detection module 200a can be activated by operating the keyboard, the mouse, the touch screen of the computer or pressing the pedal switch 420 as described above, so that the color difference detection module 200a can control the color difference detection device 200 to operate under further instructions at any time. Step 20 is mainly used for connecting the relevant equipment and activating the color difference detection module 200 a. The computer 500 includes a display screen, and the color difference detection module 200a may be configured with a display interface capable of being displayed on the display screen for viewing by a user. In the display interface of the color difference detection module 200a, it may be designed to display the login interface first, so that the color difference detection module 200a can continue to operate only after the user inputs the correct password.

In step S30, the pedal switch 420 (the left pedal switch 420 in fig. 1 and 2, for example) may be pressed, thereby instructing the color difference detection module 200a to control the color difference detection apparatus 200 to start color difference detection. Step S30 is mainly for starting color difference detection by operation of the pedal type trigger 400. For example, the camera module 300a that can operate the camera 300 can also be activated by appropriately pressing the pedal switch 420. Next, in step S40, the manufacturer' S customization module may be activated by operating the keyboard, mouse, touch screen of the computer or pressing the pedal switch 420 as described above. Step S40 is mainly used to associate the customized module of the manufacturer with the color difference detection. The manufacturer's customization module is located in the computer 500 and may also be configured with a display interface that is displayed on the display screen for viewing by the user. Fig. 4 schematically shows an example of the display interface. The manufacturer's customized module may customize the different operations and/or functional zones to its actual needs, while the pedal trigger 400 may be configured to toggle activation between the different functional zones of the manufacturer's customized module by pressing a different pedal switch 420 or pressing the pedal switch 420 with different numbers of presses per unit of time. For example, at step S50, it may be arranged that a report template for a particular vendor is selected and confirmed in the manufacturer' S customization module by pressing the pedal switch 420 (taking fig. 1 and 2 as an example, the pedal switch 420 on the right). Step 50 is primarily used to match the appearance to be inspected with the corresponding supplier. At step S60, by appropriately pressing the pedal switch 420, the manufacturer 'S customized module may be made to operate so that the color difference detection apparatus 200 automatically acquires the color difference detection data and the camera 300 automatically takes a picture of the object to be measured as the object to be measured is placed in an appropriate position in front of the color difference detection apparatus 200 and the camera 300, and the color difference detection data and the picture may be automatically imported into the selected supplier' S report template. Step S60 is mainly used to obtain color difference detection data of the object under test and associate the image of the object under test with the data so as to archive the image. Next, at step S70, by appropriately pressing the pedal switch 420, the test may be ended, for example, such that the color difference detection module 200a and the camera module 300a of the camera 300 are in an inactive state, and by being able to store the final report on a local computer or via a network to a server. Step S70 is mainly used to end the color difference detection by the trigger device.

It should be clear to those skilled in the art that the method for detecting the color difference of the exterior and interior parts by using the system 100 for detecting the color difference of the exterior and interior parts is not limited to the specific example described above, and other work flows are also applicable to the system 100 for detecting the color difference of the exterior and interior parts. For example, alternatively, a customized module of a specific manufacturer may be activated first, and then the customized module of the manufacturer automatically activates the color difference detection module 200a and the camera module 300a to work, and automatically saves the data into a report template of a corresponding supplier. For example, a reporting module may be included in the customization module, into which the detection data obtained by the color difference detection module 200a and the image data handled by the camera module 300a for each object under test can be automatically saved for archiving and subsequent tracing, depending on the operation of the pedal trigger device 400. Similar to the color difference detection module 200a, the reporting module may also have a display interface capable of being displayed on the display screen of the computer 500.

In the above-mentioned context of the present application, the modules are built into the computer 500, and the pedal-type triggering device 400 is configured such that its operation can trigger the modules accordingly and cause the devices corresponding to the modules, such as the color difference detecting device 200 or the camera 300, to operate. In this application, the term "activate" in reference to a module refers to enabling the module to be in an operational state and optionally/additionally the display interface of the module may be displayed on the display of the computer 500 or any other suitable display device for viewing by a user. The term "inactive" with respect to a module refers to rendering the module inactive while the display interface of the module may or may not be displayed on the display of the computer 500 or any other suitable display device.

The detection data of the color difference detection apparatus 200 obtained by the color difference detection module 200a and inserted into the report of the customized module of the manufacturer can be implemented by hardware or software data connection inside the computer 500, for example, a corresponding hardware interface or software interface is provided inside the computer 500 so that these modules can share data. It should be clear to those skilled in the art that the color difference detection module 200a may be integrated as a sub-module in a customized module of a manufacturer.

In the illustrated embodiment, the camera 300 is used to record and calibrate the piece under test, with a photograph thereof used as part of a report for a subsequent traceability mechanism. It will be clear to those skilled in the art that the equipment that can be used to record and calibrate the piece under test is not limited to the camera 300 mentioned. For example, in an alternative embodiment, in the case of a tested object having a radio frequency identification tag (RFID), the camera 300 may be replaced with an RFID identification device, so that when the tested object is placed in the proper position of the color difference detection device 200, the RFID identification device can automatically identify the RFID on the tested object and record the identification result in a report for subsequent tracing. It will be clear to those skilled in the art that the above described embodiments may be combined with each other, for example in the case where the camera 300 is a suitable part appearance recording device, the part identification device may be in data connection with the computer 500 in a similar manner to the camera 300 described, while a part appearance recording module is provided in the computer 500 for operation of the part appearance recording device, and operation of the pedal trigger device 400 may activate the part appearance recording module accordingly.

Although specific embodiments of the present application have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the application. Further, it should be clear to those skilled in the art that the various embodiments described in this specification can be used in combination with each other. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present application.
