Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
An image capture frame rate measurement method and apparatus according to an embodiment of the present application are described below with reference to the drawings.
Fig. 1 is a flowchart of an image capture frame rate measurement method according to an embodiment of the present application, and as shown in fig. 1, the method includes:
It can be understood that the generation process of each frame of image is actually the process of acquiring and processing image data by the image module (including the image sensor, the image processor and other relevant hardware devices for acquiring images), and therefore, for the image module, the change of the real-time operating parameter of the power supply is necessarily reflected on the change of the real-time operating parameter of the analog power supply during operation, and the change of the real-time operating parameter of the power supply reflects the process of the image module for processing images in real time.
The real-time working parameters of the power supply comprise voltage, current, power and the like.
Specifically, real-time working parameters of the analog power supply corresponding to the image module are acquired, so that the shooting frame rate is further determined through the change of the working parameters of hardware.
In actual execution, the method for acquiring the real-time working parameters of the analog power supply corresponding to the image module includes, but is not limited to, the following methods according to different application scenarios:
as a possible implementation mode, test equipment is connected into the image module, and real-time working parameters of the corresponding analog power supply are obtained through the test equipment.
In this embodiment, as shown in fig. 2, an oscilloscope is connected to the image module, and a real-time input voltage waveform of the analog power supply corresponding to the image module is obtained through the oscilloscope, so as to further determine the image capturing frame rate according to the voltage waveform.
As another possible implementation manner, the system reads and records the real-time working parameters of the analog power supply corresponding to the image module in real time, receives a real-time working parameter acquisition request of the analog power supply sent by the external test equipment in a wireless manner, and feeds back the real-time working parameters of the analog power supply according to the request, so that the external test equipment can acquire and display the fed-back real-time working parameters of the analog power supply.
And 102, analyzing the real-time working parameter change of the analog power supply, and acquiring the time interval of the image module for acquiring adjacent frames.
And 103, acquiring the shooting frame rate of the image module according to the time interval.
Specifically, the image frame number of the image frame collected in 1 second is the image frame number, so that the image time interval of collecting adjacent frames by the image module is obtained by analyzing the change of the real-time working parameters of the analog power supply, the time t required by transmitting one frame of image can be known, and further, the 1/t can be used as the image frame number of the image module, therefore, the image frame number is finally determined according to the visual change of the real-time working parameters of hardware, the determination is easy, the accuracy is high, furthermore, the accurate assessment of the power consumption can be realized, and the optimization of the power consumption performance of the terminal equipment is facilitated.
It should be noted that, according to different application scenarios, the real-time working parameter variation of the analog power supply is analyzed, and the time interval for acquiring the adjacent frames by the image module is different, which is exemplified as follows:
the first example:
in this example, taking the application scenario corresponding to fig. 2 as an example, after the real-time input voltage waveform of the analog power supply corresponding to the image module is obtained through the oscilloscope, the peak time of the real-time input voltage waveform is detected, and the time interval of the image module for acquiring adjacent frames is obtained.
That is, according to the fact that when the image module captures a frame of an image in the actual execution process, the power consumption is relatively high and the corresponding voltage is relatively high compared to the function required when the frame of the image is not captured, as shown in fig. 3, in the voltage waveform of the image module, the peak corresponding to each voltage waveform corresponds to the capturing action of the frame of the image, so that the time interval of the image module capturing the adjacent frame can be obtained according to the peak time of the voltage waveform, and with continuing reference to fig. 3, the time interval between the peak 1 of the voltage waveform and the peak 2 of the adjacent voltage waveform is the time interval t of the image module capturing the adjacent frame.
The second example is:
the method comprises the steps of obtaining real-time input power of an analog power supply corresponding to an image module, detecting time of maximum power of the real-time input power, and obtaining time intervals of adjacent frames collected by the image module.
That is to say, in this example, according to the fact that when the image module collects the frame of the image in the actual execution process, the power consumption is required to be larger for the function when the frame of the image is not collected, so that the corresponding power is larger, and therefore, the time interval of collecting the adjacent frames by the image module can be obtained according to the time of the maximum power of the real-time input power.
Therefore, the method for measuring the camera frame rate according to the embodiment of the application obtains the camera frame rate based on the more intuitive working parameters of hardware, is simple to operate and high in accuracy, has important significance in power consumption evaluation and power consumption performance optimization, and can generate a test result in real time according to the time interval of collecting adjacent frames of the image module and the camera frame rate of the image module according to application requirements when power consumption performance evaluation is carried out.
To sum up, the method for measuring the frame rate of camera shooting according to the embodiment of the present application obtains the real-time working parameters of the analog power supply corresponding to the image module, analyzes the change of the real-time working parameters of the analog power supply, obtains the time interval of the image module collecting the adjacent frames, and further obtains the frame rate of camera shooting of the image module according to the time interval. Therefore, the analog power supply corresponding to the image module obtains the shooting frame rate, visual reading of the shooting frame rate is achieved, accuracy of the determined shooting frame rate is improved, and accurate positioning of power consumption of the image module is achieved.
Based on the above embodiment, on the premise that the camera frame rate can be obtained in real time, other performances of the terminal device can be detected according to the camera frame rate.
In one embodiment of the present application, the communication performance of the terminal device may also be determined in real time based on the camera frame rate.
Specifically, as shown in fig. 4, after the step 103, the method further includes:
Wherein the receiving device may be an image viewer, a video player, etc.
In an embodiment of the application, network resources occupied by an image transmission process from an image module to receiving equipment are obtained, and an image transmission rate from the image module to the receiving equipment is calculated according to a network speed and image data volume to be transmitted.
In another embodiment of the present application, the number of times that the called related transfer function is called when an image transmission event occurs from the image module to the receiving device is obtained, and the image transmission frame rate from the image module to the receiving device is determined according to the number of times of calling.
In step 202, it is compared whether the image capturing frame rate is the same as the image transfer frame rate.
Specifically, whether the image capturing frame rate is the same as the image transmission frame rate is compared, if the image transmission frame rate is smaller than the image capturing frame rate, the image transmission is not smooth, and therefore a communication link from the image module to the receiving device is detected, the communication link is subjected to troubleshooting or transmission rate optimization, and frame blocking of the image is avoided.
Of course, in an embodiment of the present application, if the image capturing frame rate is the same as the image transmission frame rate, it indicates that the image transmission is smooth, and at this time, the image display frame rate of the receiving device is further detected, and by comparing whether the image capturing frame rate is the same as the image display frame rate, if the image display frame rate is smaller than the image capturing frame rate, it indicates that the display is not smooth, so as to detect the display module of the receiving device, where detecting the display module includes hardware checking, checking the system computing capability, and the like, thereby eliminating a failure of the display module or performing performance optimization on the display module, and improving the display quality.
In summary, the method for measuring the frame rate of camera shooting according to the embodiment of the present application detects other performances of the terminal device according to the frame rate of camera shooting, and provides convenience for optimizing the overall performance of the terminal device.
