Abstract

A method for solving the problem that a screen pops too fast to capture relates to the technical field of computer vision and industrial automation; the method comprises the following steps: step one, a camera shoots a display screen in real time and stores the picture in a control host; judging the two pictures stored at last by the control host, and judging whether a popup exists in the pictures; driving an executing mechanism to execute button operation to complete task operation requirements; step four, at the moment when the operation of the popup button is finished, controlling the host to control the camera to take a picture of the display screen; step five, the executing mechanism continues to carry out button operation until the task operation requirement is finished; the invention aims to overcome the defects of the prior art, provides a method for solving the problem that the pop-up window of the screen is too fast to capture, selects the system sub-block drive to realize the background operation, has good effect and can achieve the effect that the visual system can capture the pop-up window information in the screen all the time.

Description

Method for solving problem that screen popup cannot be captured due to too fast speed

Technical Field

The invention relates to the technical field of computer vision and industrial automation, in particular to a method for solving the problem that a screen pops too fast to capture a video.

Background

When the control host controls the execution mechanism to execute actions, the screen popup command for controlling information transmission flashes once and cannot be captured normally, and then the control host cannot control the execution mechanism to execute the next operation.

In the prior art, a plurality of modes for capturing characteristic pictures in time exist, one mode is to use a high-speed camera for capturing, but the engineering problem is not related to the mode, and the engineering problem is caused by the fact that the camera cannot be called in the system operation process.

The other method is to adopt a parallel computing method to solve the problems, namely, to take and store pictures and control an execution mechanism to operate, but the method cannot ensure the consistency of computation, in the running process of the system, the execution mechanism performs execution actions based on the information of the pictures taken in real time, and when the pictures are taken independently, the taken section cannot be determined to belong to the required control information picture.

In another method, a camera is called to take pictures when the execution of the action of the execution mechanism is finished so as to solve the problem of incapability of capturing videos, but in the engineering, when the execution of the action is finished, a system for executing the action is still operated continuously, and the camera cannot be called.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides a method for solving the problem that the screen popup cannot be captured due to too fast speed, wherein a program for processing a photographing system and a program for processing an executing mechanism are fused together, namely after the execution action is finished, the photographing and the image taking are carried out immediately no matter whether the execution action is completely finished or not.

The above purpose of the invention is realized by the following technical scheme:

a method for solving the problem that a screen pops too fast to capture comprises the following steps:

step one, a camera shoots a display screen in real time and stores the picture in a control host; entering a second step when the number of the pictures stored in the control host is larger than or equal to the threshold number;

judging the two pictures stored at last by the control host, and judging whether a popup exists in the pictures; entering the step (III) when a popup exists; when there is no pop-up window, entering step (one);

step three, the control host sends out a control instruction according to the task operation requirement in the popup window, and drives the execution mechanism to execute button operation to complete the task operation requirement;

step four, in the process of executing button operation by an executing mechanism, when the popup button is operated, at the moment when the popup button operation is finished, the control host controls the camera to take a picture of the display screen, and stores the taken picture in the control host;

step five, the executing mechanism continues to carry out button operation until the task operation requirement is finished; finishing photographing and storing records of a display screen operated by the task; and (5) when other popup windows pop up, repeating the step (one) to the step (five).

In one of the above-mentioned methods for solving the problem that the screen pop-up is too fast to capture, in the step (one), the picture has 640 × 480 pixels.

In the above method for solving the problem that the screen pop-up is too fast to capture, in the step (one), the shooting frequency of the camera is 5-7 sheets per second.

In the above method for solving the problem of screen pop too fast to capture, in the step (one), the number of the threshold sheets is 2.

In the above method for solving the problem that the screen pop-up is too fast to capture, in the step (four), the buttons include a button on the test board surface and a button on the keyboard; wherein, the button on the keyboard is set as a popup button.

In the above method for solving the problem that the screen pop-up is too fast to capture, in the step (three), the task operation is completed by the execution mechanism to perform the operation on the button on the surface of the test board and the execution mechanism to perform the operation on the button on the keyboard.

Compared with the prior art, the invention has the following advantages:

(1) according to the invention, after the execution mechanism finishes operating the popup button, the camera is driven to shoot, so that a picture can be shot and stored at the moment when the execution mechanism finishes executing the action, and screen information at the moment is recorded, wherein the screen information is an intermediate state with or without popup information and is of great importance;

(2) according to the method, the screen photo is captured at the moment after the execution mechanism finishes the operation of the popup button, compared with other solutions, the method is simpler, clearer and more efficient, and has no influence on the global performance of the system and on the vision submodule and the execution submodule.

Detailed Description

Referring to fig. 1, which is a flowchart illustrating a capturing method, it can be seen that a method for solving the problem of screen pop-up being too fast to capture includes the following steps:

the method comprises the following steps that (A), a camera shoots a display screen in real time, wherein the shooting frequency of the camera is 5-7 pictures per second; and storing the photos in the control host; the picture has 640 x 480 pixels; when the number of the photos stored in the control host is more than or equal to 2, entering the step (II);

step three, the control host sends out a control instruction according to the task operation requirement in the popup window, and drives the execution mechanism to execute button operation to complete the task operation requirement; the task completing operation comprises the execution of the button on the test board surface by the execution mechanism and the execution of the button on the keyboard by the execution mechanism.

Fourthly, the buttons comprise buttons on the test board surface and buttons on a keyboard; wherein, the button on the keyboard is set as a popup button. In the process of operating the button by the executing mechanism, when the popup button is operated, the control host controls the camera to shoot a display screen at the moment when the popup button is operated, and the shot picture is stored in the control host;

Those skilled in the art will appreciate that those matters not described in detail in the present specification are well known in the art.
