Referring to fig. 2, in a preferred embodiment, in order to achieve accurate positioning of the intelligent terminal and ensure that the film does not deviate during film covering, the method for positioning the film on the intelligent terminal includes the following steps:
s100: controlling an intelligent terminal to be filmed to be placed on a tool base, and controlling a display interface of the intelligent terminal to be a white screen interface
Referring to fig. 1, in order to attach the film to the intelligent terminal, the intelligent terminal needs to be first positioned, and for this, the intelligent terminal to be attached with the film is placed on a tool base. The middle part of the tooling base is provided with an accommodating cavity, and the intelligent terminal can be just clamped into the accommodating cavity and is in clearance fit or close fit with the tooling base. The mounting means may be manual snap-in or machine-grip snap-in. The raw materials of the tool base can be processed by selecting milky POM materials, and firstly, the shell (generally black) of the intelligent terminal and the tool base are obviously chromatism in color so as to perform rough positioning for subsequent camera shooting.
For further highlighting the boundary of the intelligent terminal and the tool base, the display interface of the intelligent terminal is displayed as a white screen interface, so that the products on two sides of the intelligent terminal are all highlighted in a white mode to make the follow-up photographing more convenient.
S200: the film sticking device sucks a film, shoots the film to form a film image, and marks a first center of the film in the film image and the position of a first rectangular frame comprising the center in the film image
The film sticking device sucks the film to be stuck on the intelligent terminal, and takes pictures of the film and the edge background attached to the film after the film sticking device sucks the film to form a film sticking image. In general, the border of the overlay film is significantly different from its background, e.g., the background is black and the overlay film is clear or white, then the overlay film image preferably includes only the complete overlay film.
After the photographing is completed, the first center (i.e., the most central position) of the overlay film in the overlay film image and the position of a first rectangular frame including the first center in the overlay film image are calibrated. For example, each pixel of the overlay film image is expressed in a dot coordinate form, and the positions of the first center and each frame of the first rectangular frame including the first center in the overlay film image are also expressed in a dot coordinate form and a straight line analytic expression form.
S300: the film pasting device takes the boundary of the white screen interface and the tool base as a viewing area, shoots the intelligent terminal to form a terminal image, and marks a second center of the terminal image and the position of a second rectangular frame comprising the second center in the terminal image
On the other hand, the film sticking device also needs to shoot and view the display interface of the intelligent terminal. Specifically, the film sticking device takes the boundary between the white screen interface and the tooling base as a viewing area, shoots the picture of the intelligent terminal and forms a terminal image. Due to the color of the tool base, the color of the display interface of the intelligent terminal is matched with the edge differentiated color of the intelligent terminal, and the shot terminal image only comprises the whole intelligent terminal, preferably without background. Meanwhile, the size of the overlay film of the general intelligent terminal is quite close to that of the intelligent terminal, so that the length and width of the terminal image are basically the same as those of the overlay film image. With this feature, the second center (i.e., the most central position) of the terminal image and the position of a second rectangular frame including the second center in the terminal image will also be calibrated. For example, each pixel of the terminal image is expressed in the form of point coordinates, and the positions of the second center and each frame of the second rectangular frame including the second center in the terminal image are also expressed in the form of point coordinates and a straight line analytic expression. And it is understood that the first rectangular frame and the second rectangular frame are the same size to have the same reference standard.
S400: the film pasting device aligns the first center, the second center and the positions of the first rectangular frame and the second rectangular frame and then stabilizes the film covering
The film sticking device compares the film sticking image with the terminal image, and the comparison objects are a first center and a second center, and a first rectangular frame and a second rectangular frame. Specifically, when the first center and the second center are aligned with each other, the center positions of the overlay film image and the terminal image are aligned, and when the first rectangular frame and the second rectangular frame are overlapped with each other, the lengths of the overlay film image and the terminal image are also aligned with each other, so that the positions of the overlay film and the intelligent terminal can be aligned with each other.
In this case, the film coating device will stabilize the position of the coating film, and the sticking will not be deviated.
S500: the film pasting device controls the film pasting to be arranged on the intelligent terminal
After the two are aligned with each other, the film pasting device controls the film to be pasted on the intelligent terminal from top to bottom, and the film pasting operation is completed.
In a preferred embodiment, step S100 includes:
s110: installing an application program in an intelligent terminal;
before the intelligent terminal is installed on a tool base, in a more preorder step, an application program is installed in the intelligent terminal, needs to be installed on a bottom layer and needs to be activated in a certain special mode.
S120: placing an intelligent terminal to be filmed on a tool base, and clamping the intelligent terminal in the tool base for stability;
s130: activating an application program, controlling a display interface of the intelligent terminal to be a white screen interface, and adjusting the authority of the bright white screen event in the intelligent terminal to be the highest level
After the position of the intelligent terminal is determined, the application program is activated, wherein the activation mode can be that an installer of the intelligent terminal configures the application program, when the intelligent terminal receives a password instruction input and is matched with a preset password, the intelligent terminal is regarded as inputting a correct instruction, based on the correct instruction, the application program controls the display interface of the intelligent terminal to display a white screen interface, the brightness is 50%, the authority of the display event of the white screen interface is the highest level, and the display of the white screen interface is maintained even if other instructions are received, such as pressing a power key and point-touching a desktop key.
In a preferred embodiment, step S200 includes:
s210: absorbing a film by a film sticking device;
s220: the camera equipment arranged on the film sticking device takes the boundary of the film and the background as a viewing area to shoot a film sticking image;
s230: the film sticking device acquires a film covering image from the camera equipment and acquires a diagonal intersection point along the film covering image as a first center;
considering that the size of the overlay film is usually a rectangle, two diagonal lines of the overlay film image (only drawn on the overlay film image) need to be drawn for the first center selection, and the intersection point of the two diagonal lines is the center of the rectangle, that is, the center of the overlay film.
S240: the film sticking device acquires any point on a diagonal line of the film coating image as a first acquisition starting point, and acquires and records a first distance from the first acquisition starting point to a first center;
a point is arbitrarily taken on the diagonal line of the overlay film image, and preferably, the point may be a point closer to the first center. And defining the point as a first acquisition starting point, and recording a first distance from the first acquisition starting point to the first center. This first acquisition start point will constitute a first rectangular box.
S250: taking rays parallel to the boundary of the film covering image from the first acquisition starting point clockwise or anticlockwise until the rays intersect with the diagonal line of the film covering image to form a first acquisition inflection point;
if a ray parallel to the boundary of the overlay film image is taken clockwise or counterclockwise with the first acquisition starting point as a starting point, the intersection point will be defined as a first acquisition inflection point when the ray intersects with the diagonal line.
S260: repeating the step S250 until the ray returns to the first acquisition starting point, and sequentially connecting each first acquisition starting point and each first acquisition inflection point to form a first rectangular frame;
the above rays are made continuously and eventually three acquisition inflection points will be obtained. The first rectangular frame is formed after the three acquisition inflection points and the acquisition initial point are connected.
Alternatively, the steps S250 and S260 may be replaced by, after the first collection starting point is selected, selecting another end point as the collection inflection point on the diagonal line by using the first distance as the standard, the first center as the end point, and the other end point as the collection inflection point. Or, the first center is taken as the center of a circle, the first distance is taken as the radius to make a circle, and the position intersected with the diagonal line is taken as the acquisition inflection point.
S270: the length from the first center to the boundary is obtained and recorded.

s330: a point, which is on the diagonal line of the film laminating image and is a first distance from a second center, is acquired as a second acquisition starting point by the film laminating device;
in this step S330, the selected position of the second acquisition starting point is not arbitrary, but a first distance is also used as a standard, so that the first acquisition starting point and the second acquisition starting point should overlap (i.e. the same position) in the aligned state.
S340: making a ray parallel to the boundary of the terminal image from the second acquisition starting point clockwise or anticlockwise until the ray is intersected with the diagonal line of the terminal image to form a second acquisition inflection point;
s350: repeating the step S340 until the ray returns to the second acquisition starting point, and sequentially connecting each second acquisition starting point and each second acquisition inflection point to form a second rectangular frame;
