Therefore, the embodiment of the application receives a selection instruction, wherein the selection instruction is used for selecting the first image acquisition device from the candidate image acquisition devices, and the candidate image acquisition devices are communicated with the upper computer; according to the address information of the first image acquisition device, an image acquisition device object corresponding to the first image acquisition device is established in the factory class; and calling image acquisition subclasses corresponding to the types of the first image acquisition devices through the image acquisition device objects so as to call the first image acquisition devices to acquire images, wherein each type of image acquisition device is provided with one corresponding image acquisition subclass, and the image acquisition subclasses corresponding to the multiple types of image acquisition devices inherit the same image acquisition base class. The method for calling the camera to take the picture is not limited to a single type of camera, the simple factory mode is adopted, so that the method for taking the picture of multiple types of cameras and other related methods can be inherited to the image acquisition class, and related camera objects can be instantiated in the factory class only by acquiring related information of the selected camera, so that the camera can be called, the expandability is strong, the maintenance is easy, and the technical problem that in the prior art, due to the fact that the calling methods of multiple cameras at the front end of a visual detection system are different, the calling methods need to be written for cameras of each brand respectively, and the reusability of a program is poor is solved.

In the above solution, according to the physical address information specific to the camera, a corresponding unique camera object is created from a corresponding brand camera image capture class, so that the setting of camera parameters can be implemented, for example: the camera has the advantages of exposure value, gain value, Gamma value, black-white/color mode selection and software/hardware mode selection, and can select single-sheet shooting or real-time acquisition for effect viewing on an editing interface.
Still referring to fig. 2, after a camera is selected and a unique camera object is created for the selected camera in the factory class, camera parameters of the camera, including an exposure value, a gain value, a Gamma value, a black-and-white/color mode selection, a software/hardware mode selection, and the like, are returned to the human-computer interface at the front end, a user may modify the camera parameters on the human-computer interface, and the human-computer interface modifies the camera parameters of the first camera according to the parameter modification instruction after receiving the parameter modification instruction.

Fig. 4 is a schematic diagram of a method for compiling a call of an image capturing apparatus according to an embodiment of the present invention, and in an alternative embodiment, an image capturing base class may be first compiled, and this base class is responsible for describing an interface method common to all instances, and contains a virtual function: write camera parameter setparameter (), read camera parameter getparameter (), initialize connected camera connet (), camera photographing pyramid (), release camera close (), and the like. Then, the image acquisition methods of various brands of cameras are written into subclasses of image acquisition classes, wherein the subclasses are the creation targets of simple factory models. And inheriting the parent class, rewriting and writing camera parameters, reading the camera parameters, initializing and connecting the camera, photographing the camera, releasing the camera and the like. And finally, compiling a core class, namely a factory class, of the whole image acquisition module, wherein the class is mainly responsible for realizing the internal logic of creating all instances, reading the names of all equipment connected with the cameras when an editing interface of the image acquisition module is opened, wherein the equipment names contain camera brand information, and when a client selects the cameras, the factory class creates objects of corresponding brands by selecting camera brand names, so that the image acquisition classes of the cameras of the corresponding brands are called.

According to the scheme, under the condition that a new type of image acquisition device is added, a corresponding image acquisition subclass is compiled for the newly added image acquisition device, and the image acquisition subclass inherits a previous image acquisition base class, so that the newly added image acquisition device can be called.
The method facilitates the addition of a new type of image acquisition device, and the newly added image acquisition device only needs to add methods of inheriting an image acquisition parent class, rewriting read-write parameters, initializing a camera, photographing and the like, and add a creation object code of the newly added type of image acquisition device in a factory class. The maintenance of the existing image acquisition devices is also facilitated, and when an abnormality occurs in the photographing process of a certain type of image acquisition device or a new function is added to the type of image acquisition device, only the method in the image acquisition subclass of the type of image acquisition device needs to be modified and adjusted.
In summary, most image acquisition modules of the visual inspection system software are mainly used for customizing cameras of related brands, and after the cameras are selected, methods of reading and writing camera parameters, photographing pictures and the like need to judge the camera types, so that the method is complex and chaotic, development codes of different cameras are inconvenient to add and maintain, and the development cycle is seriously influenced. The method is applicable to various required selections. Compared with the traditional method for customizing and developing image acquisition, the scheme provided by the application has the following advantages: the scheme adopts a simple factory mode, firstly a father class for image acquisition is compiled, virtual function camera initialization, camera photographing, camera releasing and other methods are arranged in the father class, then the image acquisition of various brands of cameras is written into subclasses of the image acquisition class, and after the father class is inherited, the methods of camera initialization, camera photographing, camera releasing and the like are rewritten. Finally, a factory class is written to instantiate the objects of the corresponding brand of camera. Therefore, the new brand camera is added only by adding the subclass of the camera and adding the object for instantiating the brand camera in the factory class, so that the expansion and maintenance of various brand cameras are facilitated, and the development and maintenance time is shortened.
