Embodiment 1

[0074] Such as figure 1 , figure 2 As shown, the present invention is based on the visual alignment method of the area to be imaged adaptively, and the method comprises the following steps:

[0075] S1: Obtain the ATI feature database corresponding to the operating platform A and operating platform B where the object a and the object b are respectively located, the ATI feature database includes the template image MP and its characteristic image related coordinates and related parameters; simultaneously obtain the operating platform A. Calibration parameters of operating platform B;

[0076] S2: According to the acquired ATI feature database, set the photosensitive area of ​​the chip of the feature image corresponding to the acquisition device as the area to be imaged, and calculate the area to be imaged of object a and object b respectively; Image acquisition; wherein, the acquisition device may be a camera;

[0077] S3: Find the feature images corresponding to the respect...

Embodiment 2

[0086] Such as Figure 1 to Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that in the embodiment of the present invention, such as image 3 As shown, the construction process of the ATI feature database in step S1 is:

[0087] Step A: Collect several sample images (usually 100-200 sample images) for object a and object b respectively located on operating platform a and operating platform b to obtain image set a of object a and image set of object b b;

[0088] Step B: Find the feature image corresponding to the template image a of the object a in each image of the image set a, obtain the diagonal coordinate information of the feature image, and calculate the horizontal and vertical coordinates of each coordinate point according to the coordinate information Average value and variation range, obtain the ATI feature database a of operating platform a;

[0089] Find the feature image corresponding to the template image b of the object b in each ...

Embodiment 3

[0113] Such as Figure 1 to Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the alignment method of embodiment 1 or embodiment 2 is applied in the actual production process of precision assembly through machine operation process adjustment.

[0114] This is considering that in the actual production process, through the adjustment of the machine operation process, even if the position of the workpiece to be aligned is slightly different, the range of change should be controlled within a certain range, that is, the position does not change much during the process. alignment process.

[0115] In this embodiment, the bonding of mobile phone screens is taken as an example. The variation range of the placement position of the screen parts that need to be precisely assembled is about 1 cm. Otherwise, an excessive variation range will cause the assembly manipulator to travel too far, affecting production efficiency and assembly accuracy. . The matc...

Abstract

The invention discloses a visual alignment method, device, equipment, and storage medium based on an area to be imaged. The method includes: acquiring the ATI feature database corresponding to the operating platform A and the operating platform B where the object a and object b to be aligned are respectively located and Calibrate parameters; set the photosensitive area of ​​the chip corresponding to the feature image acquisition device as the area to be imaged, and calculate the area to be imaged of object a and object b respectively; and perform image acquisition on the area to be imaged; find out in the calculated image of the area to be imaged Get the feature image corresponding to the respective template image, determine the corresponding position of the feature image, and obtain the positions of object a and object b respectively; at the same time, substitute the position of the current feature image into the corresponding operating platform to update its ATI feature database, and update object a , the area to be imaged of object b; and then realize the alignment of object a and object b. The invention improves the working efficiency of visual alignment.

Description

technical field [0001] The invention relates to the technical field of visual alignment, in particular to a visual alignment method, device, equipment and storage medium based on an area to be imaged. Background technique [0002] Alignment is a professional name for the precision assembly of devices in modern industrial production. Its typical applications are the installation of various flexible or rigid devices typically represented by mobile phone production. The specific implementation process is to install the object a at position A and the object b at position B together. During the installation process, the horizontal, vertical or rotational direction of object a or object b needs to be adjusted. A key link in realizing the alignment function is whether the precise positions of the above-mentioned object a and object b can be obtained. In order to achieve precise adjustment of the position, the object will be photographed through the visual alignment system during w...
