Referring to fig. 1, fig. 1 is a block diagram illustrating a first embodiment of a camera on-time testing system according to the present invention.
As shown in fig. 1, the camera on-time test system includes: a trigger mechanism 10, a test terminal 20, and a target camera 30; the trigger mechanism 10 is connected to the test terminal 20 and the target camera 30, respectively.
It should be noted that, the system provided in this embodiment may be applied in a scene where a time parameter of a camera needs to be tested, for example, in a test of starting a snapshot speed of an outdoor camera, or in other scenes where a camera starting time needs to be obtained. The present embodiment and the following embodiments will be described herein with reference to the camera on-time test system (hereinafter referred to as a system).
The triggering mechanism 10 is configured to output a first signal to the test terminal 20 and the target camera 30 when receiving a test instruction.
It should be noted that, the test instruction may be an instruction issued at a preset time interval, or may be an instruction issued at any time based on user personalized selection, which is not limited in this embodiment.
The trigger mechanism 10 may be a device independent of the test terminal 20, and the trigger mechanism 10 may have a first connection line and a second connection line, which are connected to the test terminal 20 and the target camera 30, respectively, and output a first signal through the first and second connection lines.
It will be appreciated that the first signal may be a high level signal for triggering the test terminal 20 to time and the target camera 30 to perform a start snapshot function, the first signals being sent to different destinations being sent simultaneously by the trigger mechanism 10.
It should be understood that the triggering mechanism 10 may also be an external device attached to the test terminal 20, for example, the triggering mechanism 10 may be a highly sensitive mouse or a control button, and the time for outputting the first signal may be specifically determined by left clicking or pressing the button with the mouse.
The test terminal 20 is configured to start timing when receiving the first signal output by the trigger mechanism 10.
It should be noted that the test terminal 20 may be any computing electronic device that has a timing function and is capable of displaying a timing time, such as a personal computer, a tablet computer, a timer, and the like. The test terminal 20 may begin timing upon receiving an electrical signal from the trigger mechanism 10.
It will be appreciated that, considering the transmission speed of the electrical signal and the accuracy requirement of the camera on time obtained by the test, the minimum timing unit may be milliseconds or microseconds in the test terminal 20.
The target camera 30 is configured to perform a camera start operation when receiving the first signal output by the trigger mechanism 10, and take a picture of the test terminal 20 to obtain a first timing time on the test terminal 20 when the camera start is completed.
It can be understood that the target camera 30 may be independent of the test terminal 20, and directly connected to the trigger mechanism 10 by a wire to realize electric signal transmission and control, and the target camera 30 may be a security camera, a hunting camera, an outdoor camera, or a camera with a snap-shot function, in which an infrared sensor (PIR) is installed.
It should be noted that, the target camera 30 may default to a sleep mode with low power consumption, and when receiving the first signal output by the trigger mechanism 10, directly enter a shooting mode from the sleep mode, perform a camera start operation, and take a picture of the test terminal 20, so as to obtain a first timing time obtained by timing on the test terminal 20.
It should be appreciated that the target camera 30 may align the camera's viewfinder with the test terminal 20 that needs to be clocked before receiving the first signal so that the target camera 30 can obtain the first clocked time displayed on the test terminal 20 within the viewfinder when the camera start-up and photographing is completed.
The embodiment provides a camera on time test system, which comprises: the system comprises a trigger mechanism, a test terminal and a target camera; the triggering mechanism is respectively connected with the test terminal and the target camera; the triggering mechanism is used for respectively outputting first signals to the test terminal and the target camera when receiving a test instruction; the test terminal is used for starting timing when receiving a first signal output by the trigger mechanism; and the target camera is used for executing a camera starting operation when receiving the first signal output by the triggering mechanism, and photographing the test terminal when the camera starting is completed so as to acquire the first timing time on the test terminal. Because the triggering mechanism outputs signals to the test terminal and the target camera simultaneously in the embodiment, the target camera can take a picture to directly acquire the timing time on the test terminal after responding to start, so that the convenient test of the target camera can be realized, and accurate test data can be acquired while the test speed is improved.
Referring to fig. 2, fig. 2 is a block diagram illustrating a second embodiment of a camera on-time testing system according to the present invention.
Further, considering that the first timing time acquired by the target camera after receiving the first signal may include a camera opening time and a camera shutter response capturing time, in order to obtain a more accurate and detailed test result, the trigger mechanism 10 may be further configured to acquire the shutter response capturing time of the activated target camera, and output a second signal to the test terminal 20 and the activated target camera 30 when receiving the capturing instruction, respectively.
The test terminal 20 is configured to start timing when receiving the second signal output by the trigger mechanism 10.
The target camera 30 is configured to capture a snapshot when receiving the second signal output by the trigger mechanism 10, and take a photograph of the test terminal 20 to obtain a second timing time on the test terminal.
It will be appreciated that the second timing time may be a shutter response snapshot time obtained by photographing the test terminal 20 when the activated target camera 30 receives the second signal for indicating to take a snapshot.
Further, the test terminal 20 further includes: a control module 201, a timing module 202 and a display module 203; the timing module 202 is respectively connected with the control module 201 and the display module 203;
the control module 201 is configured to control the timing module 202 to start timing when receiving the first signal output by the trigger mechanism 10.
The display module 203 is configured to display the first timing time of the timing module 202.
It will be appreciated that, since the target camera 30 obtains the first timing time by photographing the test terminal 20, a module capable of displaying the timing time of the timing module 202 in real time may be included in the test terminal 20. The display module 203 can precisely display the time data recorded by the minimum timing unit of the timing module 202.
The control module 201 is further configured to control the timing module 202 to stop timing after the target camera 30 photographs the test terminal 20, so as to obtain a first timing time when the timing is finished.
It can be understood that the control module 201 may control the timing module 202 to stop timing when detecting that the target camera 30 finishes photographing, and obtain the time obtained by timing by the timing module 202 at this time, that is, the first timing time, which is the total time spent by the target camera from the sleep mode to the photographing mode and completing one photographing task.
The control module 201 is further configured to control the timing module 202 to initialize and perform timing when receiving the second signal output by the trigger mechanism 10.
It will be appreciated that after the recording of the first timing time, the timing module 202 may first initialize upon receiving the second signal, so that the second timing time obtained later is the time of re-recording from zero independent of the first timing time.
The display module 203 is configured to display the second timing time of the timing module 202.
The control module 201 is further configured to control the timing module 202 to stop timing after the target camera 30 captures the test terminal 20, so as to obtain a second timing time when the timing is finished.
It should be noted that, when the control module 201 detects that the target camera 30 completes the snapshot, it controls the timing module 202 to stop timing, and obtains the time obtained by the timing module 202 at this time, that is, the second timing time, which is the time consumed when the target camera 30 completes a snapshot task from the standby mode to the shooting mode.
It will be appreciated that in order to obtain more accurate and detailed camera on-time test data based on the first and second timing times, the test terminal 20 further comprises: a calculation module 204; the calculation module 204 is connected to the control module 201 and the display module 203.
The calculating module 204 is configured to receive the first timing time and the second timing time output by the control module 201, and calculate the camera start time according to the first timing time and the second timing time.
When the first timing time including the camera opening time and the camera shutter response snapshot time and the second timing time including the camera shutter response snapshot time are obtained, the camera opening time may be obtained from a difference between the first timing time and the second timing time.
The display module 203 is further configured to display the camera start time determined by the calculation module 204.
It can be understood that the camera start time calculated by the calculation module 204 can be displayed by the display module 203, so that the user can directly obtain the start time of the camera.
It should be noted that, because the value of the response snapshot time of the shutter of the camera is smaller, the first timing time and the camera start time are not greatly different in value, so that the first timing time can also be directly used as the final measured camera start time in the actual test data.
In order to obtain a more accurate and detailed test result, the test terminal is further limited to include a control module, a timing module and a display module, and the test terminal further includes a calculation module, and further determines a camera start time according to a first timing time and a second timing time obtained by respectively timing through the calculation module, so that it can be considered that the first timing time obtained by photographing the test terminal after receiving the first signal by the target camera includes a camera start time and a camera shutter response snapshot time, and the camera shutter response time is timed based on the started camera through the timing process, so as to obtain an independent camera start time. The second timing time and the determined camera starting time obtained in the embodiment are further refinement of the obtained starting time test data of the target camera, so that the accuracy of the test data is improved while the convenience of the test is ensured.
In addition, referring to fig. 3, fig. 3 is a flowchart of a first embodiment of a camera on-time testing method based on a camera on-time testing system according to the present invention, and an embodiment of the present invention further provides a camera on-time testing method, where the system includes: the method for testing the camera opening time comprises the following steps of:
