In order to better understand the technical scheme of the invention, the following detailed description of the embodiments of the invention is made with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Fig. 1 shows a flowchart of a test information acquisition method according to an embodiment of the present invention.
As shown in fig. 1, a test information acquisition method according to an embodiment of the present invention includes:
102, acquiring a monitoring image sequence for testing the touch screen, wherein the monitoring image sequence comprises a plurality of monitoring images which are arranged in sequence according to shooting time, a touch screen is shot in each monitoring image, and a signal indicating device which is connected with a switch of the touch piece in series and is arranged in a peripheral circuit of the touch piece is shot.
In the process of testing the touch screen, the response condition of the touch screen to the touch operation needs to be monitored, and a basic condition is created for determining the response time of the touch screen to the user operation. Based on the method, the test process of the touch screen can be monitored, the monitoring images are obtained, and a plurality of monitoring images which are shot successively are arranged successively according to the shooting time to form the monitoring image sequence.
In the process of testing the touch screen, the touch screen can be touched by the touch piece. The touch control piece comprises but is not limited to a touch control pen or a touch control finger sleeve, the switch is a contact point in the touch control pen or the touch control finger sleeve, and when the touch control piece is used for touch control operation on a screen, a working circuit in the touch control piece is communicated through the touch control point. Specifically, in response to the operation of touching the screen by the touch control member, the switch of the touch control member is closed, so that the touch control working circuit of the touch control member is conducted, and the touch control function is realized. At the moment, a switch of the touch control piece is externally connected with a touch control piece peripheral circuit, the switch is connected with the signal indicating device in series in the touch control piece peripheral circuit, when the switch is closed, the touch control piece peripheral circuit is also conducted, and the signal indicating device enters a working state, namely an effective indicating state, so that a signal indicating function is realized.
Certainly, the touch piece peripheral circuit is provided with a power supply device for providing voltage for the touch piece peripheral circuit, and the power supply device can be an independent battery or any electronic equipment with a battery, wherein the battery can be used for external connection. The signal indicating device includes, but is not limited to, an LED lamp, a display screen, and any other device capable of displaying a signal that is not available before power-on after power-on.
And 104, acquiring a last frame image of the signal indicating device in an effective indicating state and a first frame image of a processing result of the touch operation displayed by the touch screen in the monitoring image sequence, wherein the signal indicating device is in the effective indicating state in the process of performing the touch operation on the touch screen by a user by using the touch control piece.
For monitoring the image sequence, when the touch control part touches the screen, the touch control working circuit of the touch control part and the external circuit of the touch control part are simultaneously conducted, so that the signal indicating device enters a working state and displays signals. For example, if the signal indicating device is an LED lamp, for single touch, when the touch control member touches the screen, the signal indicating device enters a working state, the LED lamp is on, and when the touch control member leaves the screen, the signal indicating device is powered off, and the LED lamp is turned off.
In this way, in a single touch, the signal indicates the end time of the valid indication state of the device, i.e. the time when the touch operation is completed, and the touch screen initially displays the processing result of the touch operation, i.e. the time when the touch screen generates the touch result in response to the touch operation to change the touch screen, and the time interval between the two is the response time of the touch screen to the user operation.
In one possible design, the step of obtaining an end frame image of the signal indicating that the apparatus is in the active indication state in step 104 includes: identifying the signal indicating device in each monitoring image in the monitoring image sequence by a preset image identification mode; detecting a signal indication state of the signal indication device in each monitoring image; and determining the monitoring image with the signal indicating state being in the effective indicating state and the shooting time being the latest as the last frame image with the signal indicating device being in the effective indicating state.
The first frame of image reflects the initial time of the response time of the touch screen to the user operation. And, the predetermined image recognition mode includes, but is not limited to, a depth-first search algorithm, a breadth-first search algorithm, a convolutional neural network, etc., and the signal indicating device can be recognized in each monitored image through the predetermined image recognition mode.
Further, it is necessary to identify whether the signal indicating device in the monitored image is in a valid identification state.
In one possible design, it is detected whether the brightness parameter of the signaling device in each of the monitoring images is within a specified brightness parameter range, wherein if the brightness parameter of the signaling device in the monitoring image is within the specified brightness parameter range, it is determined that the signaling device is in a valid indication state. The signal indicating device carries out signal indication, and has higher brightness in the effective indication state no matter the signal indicating device is an LED lamp or a display screen, so that the brightness parameter of the signal indicating device in the monitored image can be used as the condition for screening the monitored image of which the signal indicating device is in the effective indication state. Wherein, the designated brightness parameter range is the range of the display brightness of the signal indicating device under the condition of effective indication state.
In another possible design, whether the display information of the signal indicating device in each monitoring image is the designated indication information is detected, wherein if the display information of the signal indicating device in the monitoring image is the designated indication information, it is determined that the signal indicating device is in the valid indication state. For the display screen, it is necessary to display contents to indicate that it is in an effective display state, and therefore, the display screen may be set to display the specified display information. When detecting whether the display screen is in an effective indication state, whether the appointed display information is displayed on the display screen in the monitoring image can be detected, and if so, the display screen is in the effective indication state.
According to the technical scheme, effective indication states of different types of signal indication devices can be effectively identified, and a solid foundation is laid for calculating the response time of the touch screen to user operation.
In one possible design, the step of obtaining the first frame of image of the touch screen displaying the processing result of the touch operation in step 104 includes: determining a plurality of target images matched with preset images in the monitoring image sequence, and determining a first frame image in the plurality of target images as a first frame image of a processing result of the touch operation displayed by the touch screen; or detecting whether each monitoring image in the monitoring image sequence is matched with the preset image according to the sequence of shooting time, and determining the first detected monitoring image as a first frame image of a processing result of the touch operation displayed on the touch screen when the monitoring image matched with the preset image is detected for the first time, wherein the preset image comprises the touch screen displaying the processing result of the touch operation.
Therefore, an image matched with the preset image of the touch screen displaying the processing result of the touch operation can be identified in the plurality of monitoring images in an image identification mode, namely the touch screen displays the first frame image of the processing result of the touch operation, and the first frame image reflects the end time of the response time of the touch screen to the user operation, so that a solid foundation is laid for calculating the response time of the touch screen to the user operation.
And 106, determining the response time of the touch screen to the user operation based on the last frame image, the first frame image and a preset monitoring image shooting frame rate.
And the difference frame number of the last frame image and the first frame image is the frame number shot in the response time of the touch screen to the user operation. Further, determining the product of the reciprocal of the preset monitoring image shooting frame rate and the difference frame number as the response time of the touch screen to the user operation. Namely, the time interval from the end of the signal indicating device to the display operation result of the touch screen is used as the response time of the touch screen to the user operation.
In summary, the working state of the device can be indicated by shooting the working state of the device for acquiring the signal externally connected to the touch piece in the test process of the touch screen, and the time interval from the end of the working of the device for indicating the signal to the display of the operation result of the touch screen is taken as the response time of the touch screen to the user operation.
