Technical Field

Background

When a user triggers the device, the device may generate a preset response change for the trigger operation, the preset response change does not occur synchronously with the trigger operation, and the preset response change can be generated only by sending a control instruction to a relevant component after the preset processing is performed by a control system of the device. Then, from the occurrence of the triggering operation until the preset response change of the device occurs, the elapsed time period is the response time period of the device for the triggering operation.

In the related art, it is necessary to accurately know the response time period of the plant to the trigger operation to evaluate the response speed of the control system of the plant, thereby knowing the operation state of the control system of the plant. Therefore, in the related art, after image sampling is performed on a display screen picture of the equipment, content analysis is performed on each sampled image to determine response time, but the identification result is often inaccurate, so that the operation state of a control system of the equipment cannot be effectively described.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1A is a schematic diagram of performing image sampling in the related art. As shown in fig. 1A, when the response time of the detection apparatus 1 to the trigger operation is long, image sampling may be performed by the image sampling apparatus 2; taking as an example the triggering operation performed on the device 1 by the finger 3: the image sampling device 2 may perform continuous image sampling before and after the finger 3 performs the trigger operation, for example, high-speed video shooting such as 120 frames/second or 240 frames/second may be performed, and then by analyzing the obtained sampling images, a first sampling image in which the trigger operation occurs and a second sampling image in which a preset response change occurs are identified, and the response time period of the device 1 is calculated based on the number of image frames spaced between the first sampling image and the second sampling image and the shooting speed adopted by the image sampling device 2. For example, it is assumed that the first sample image is the i-th frame, the second sample image is the i + 8-th frame, and the photographing speed adopted by the image sampling apparatus 2 is 240 frames/second, indicating that the response time period is 8 × 1/240 — 1/30 seconds.

However, the above scheme adopted in the related art relies on accurate identification of the first sample image and the second sample image; in particular, as shown in fig. 1A, since the finger 3 is located between the image sampling device 2 and the device 1, the finger 3 inevitably causes a certain degree of obstruction to the device 1 in the sampled image obtained by the image sampling device 2. For example, as shown in fig. 1B, it is assumed that the triggering operation is performed by touching and clicking a "camera" icon on the image sampling device 2 with the finger 3, and the image sampling device 2 is located above the finger 3, so that the "camera" icon is almost completely shielded by the finger 3 in the captured sampling image shown in fig. 1B, it is difficult to distinguish whether the finger 3 has contacted the touch screen of the device 1, and it is extremely easy to make a misjudgment on the i-th frame corresponding to the first sampling image, thereby affecting the accuracy of the finally obtained response time length.

Accordingly, the present disclosure solves the above-described problems in the related art by improving a scheme of determining a response time period of a device. The following is illustrated with reference to the examples:

FIG. 2 is a flow chart illustrating a method of determining a device response time duration, as shown in FIG. 2, which may include the steps of:

in step 202, a plurality of sampling images containing a display screen picture of the device and a sampling time point corresponding to each sampling image are obtained; wherein, during image sampling, the device responds to the detected trigger operation to make the display screen picture generate preset change.

In this embodiment, the triggering operation may include any one of: the disclosure is not limited to this, for example, an operation of a preset physical key on the device, a touch operation of a touch display screen of the device, and the like.

In this embodiment, the sampling time point and the occurrence time point correspond to the same predefined time criterion; for example, both may be network points of time provided by the same network operator, or standard points of time provided by a trusted authority such as a national time service centre, etc.

In step 204, according to the sequence of the corresponding sampling time points, the earliest sampled image with the preset change in the included display screen picture is determined.

In step 206, a response time duration of the device to the trigger operation is calculated according to the sampling time point corresponding to the earliest sampled image and the occurrence time point of the trigger operation.

In this embodiment, a light emitter and a light receiver may be disposed near the device, and transmission light between the light emitter and the light receiver may be blocked during the operation of the triggering operation; the occurrence time point is a starting time point at which transmission light between the light emitter and the light receiver is blocked. For example, the light emitter may comprise a laser emitter and the light receiver may comprise a laser receiver.

Fig. 3 is a schematic diagram illustrating a scenario for determining the response time of the device according to an exemplary embodiment, where the scenario, as shown in fig. 3, includes a light emitter 41, a light receiver 42, a processing device 5, and the like, in addition to the device 1 and the image sampling device 2 shown in fig. 1A-1B. Wherein the light emitter 41 and the light receiver 42 are located near the device 1, the light emitter 41 can emit the transmission light 40 to the light receiver 42; meanwhile, the processing device 5 is connected (directly or indirectly; and, wired or wirelessly) to the image sampling device 2, the light emitter 41, the light receiver 42, and the like, respectively, and is used to finally calculate the response time period of the device 1.

How the processing device 5 accurately calculates the response time period of the device 1 through the scenario shown in fig. 3 is described in detail below with reference to fig. 4. Fig. 4 is a flowchart illustrating another method for determining a device response time period according to an exemplary embodiment, and as shown in fig. 4, the method applied to the processing device 5 may include the following steps:

in step 402, a response test is initiated.

In this embodiment, the processing device 5 may respectively issue a control instruction to the image sampling device 2, the light emitter 41, the light receiver 42, and the like, for example, issue an image sampling instruction to the image sampling device 2, so that the image sampling device 2 performs an image sampling operation, issue a first activation instruction to the light emitter 41, so that the light emitter 41 issues the transmission light 40, and issue a second activation instruction to the light receiver 42, so that the light receiver 42 returns a corresponding indication message to the processing device 5 according to a receiving state of the transmission light 40.

In step 404A, a sample image and its sampling time point are acquired.

In this embodiment, when the image sampling device 2 performs the image sampling operation, the sampling time points corresponding to each of the acquired sampling images are respectively recorded. In order to improve the recognition accuracy, the image sampling apparatus 2 may increase the sampling speed as much as possible, for example, a sampling speed of 120 frames/second, 240 frames/second, or higher may be used.

In the present embodiment, the image sampling apparatus 2 may be a dedicated apparatus, such as an ultra-high speed camera; alternatively, the image capturing device 2 may be a general-purpose device with an image sampling function, such as a mobile phone, and the like, which is not limited by this disclosure.

In step 404B, a light transmission is performed.

In the present embodiment, the transmission light 40 generated by the light emitter 41 may be any type of light; for example, the transmission light 40 may be a laser, the light emitter 41 may be a laser emitter, the light receiver 42 may be a laser receiver, or the transmission light 40 may be an infrared ray, the light emitter 41 may be an infrared emitter, the light receiver 42 may be an infrared receiver, etc., which is not limited by the present disclosure.

In step 406, when the light interruption occurs, the response test is ended, and go to step 408; otherwise, return to step 404B.

In the present embodiment, by properly setting the positions of the light emitter 41 and the light receiver 42, the transmission light 40 can be blocked during the operation of the triggering operation, so as to cause the light interruption phenomenon, and then the starting time point of the blocking of the transmission light 40 can be used as the occurrence time point of the triggering operation.

Taking the trigger operation as a touch operation for the touch display screen of the device 1 as an example. As shown in fig. 5A, the transmission light 40 can be located right near the touch display screen surface of the device 1, so that the transmission operation of the transmission light 40 can be smoothly realized between the light emitter 41 and the light receiver 42 when the finger 3 is not yet in contact with the touch display screen of the device 1. When the finger 3 comes into contact with the touch display screen of the device 1, as shown in fig. 5B, the transmitted light 40 is immediately cut off by the finger 3, so that the light receiver 42 cannot receive the transmitted light 40.

Then, the light receiver 42, upon receiving the transmission light 40, may return a first indication message to the processing device 5; the light receiver 42 may return a second indication message to the processing device 5 when the transmission light 40 cannot be received, so that the processing device 5 immediately knows the occurrence status of the trigger operation according to the change of the indication message. For example, the first indication message may be a high level signal, and the second indication message may be a low level signal, although the disclosure is not limited thereto.

In addition, in addition to the touch operation on the touch display screen of the device 1, the trigger operation of the present disclosure may also be in any other form, for example, an operation on a preset physical key (for example, the physical key may be a volume key, a power key, a camera key, etc.) on the device 1 may also be used, and the present disclosure is not limited thereto.

In step 408, a point in time of occurrence is determined.

In step 410, the time points are compared to obtain a response time duration.

In this embodiment, the processing device 5 may record the corresponding time point immediately upon receiving the second indication message returned by the light receiver 42 as the occurrence time point of the trigger operation.

In this embodiment, the sampling time point and the occurrence time point correspond to the same predefined time standard, such as a network time point provided by the same network operator, or a standard time point provided by a trusted authority such as a national time service center, etc., and both the sampling time point and the occurrence time point may be absolute time points, such as 2016, 6, 27, 10, 14, 32, and 50 milliseconds, so that the response time duration can be obtained by calculating the interval time duration between the sampling time point and the occurrence time point.

For example, assuming that the occurrence time point is 50 milliseconds at 2016, 6, 27, 10 hours, 14 minutes and 32 seconds, and the identification and analysis of the sample images can determine that a preset change (for example, a preset content change occurs on the display screen of the device 1) occurs in the sample images, and the corresponding sample time point of the sample images is 62 milliseconds at 2016, 6, 27, 10 hours, 14 minutes and 32 seconds, the time difference between the two, i.e., 12 milliseconds, can be calculated.

The processing device 5 may receive a selection instruction input by a user to select a sampling image identified by the user and having a preset change; alternatively, the processing device 5 may automatically identify the sampled image in which the preset change has occurred by comparing each sampled image with a predefined standard image; alternatively, the processing device 5 may automatically recognize the sample image in which the preset change has occurred through automatic image recognition and image analysis by comparison between adjacent sample images. Of course, the processing device 5 may also take other forms, and the disclosure is not limited thereto.
