Description
Technical Field
The invention relates to the technical field of detection of color change response time of a color change device, in particular to a detection method and a detection device of color change response time of the color change device and a computer readable storage medium.
Background
Color-changing devices (devices such as electrochromic devices, photochromic devices, etc.) have begun to be increasingly used, such as exterior wall glass of buildings, color-changing housings of electronic devices, color-changing clothes, etc. Among them, several most important index tests of the color-changing device, such as color-changing response time, color-changing efficiency, etc., are mainly tested and analyzed by the academic and industrial circles through the transmittance change of the device. Taking the color change response time as an example, the color change response time of the color changing device is roughly defined by the difference between the peak transmittance and the valley transmittance.
The test solutions based on transmittance change are only for transparent devices, but are not applicable if there are other opaque films or light transmitting non-uniform media, such as color changing devices combined with textured films, frosted glass, etc. as substrates. Under the condition, the performance of the product to be monitored can be tested only in the middle of the manufacturing process, and the performance of the semi-finished product is tested when the color-changing device is not attached with other film layers, so that the performance test of the finished product is useless.
In addition, in the conventional technology, the definition standard is fixed singly, so the detection result cannot reflect the actual situation of the sample. Generally, 90% of the time Δ T for the color changing device to change from one color state (e.g., a transparent state) to another color state (e.g., a red colored state) is taken as the color change response time, but this test does not accurately reflect the actual senses of the human eye. If 90% of the complete color change time (under the standard normal temperature environment) is taken as the color change response time, the possible time is longer, and an experiment is carried out by taking an electrochromic device of one model as an example, the experiment result shows that the response time is as long as 10s by taking 90% of the complete color change time as the color change response time, but a plurality of assessment volunteers invited in the experiment process carry out real-time observation, and the obtained result is that: the evaluation volunteers generally think that the sample completely discolors (meets the discoloration requirement) when the discoloration lasts for about 4-5 s. This large difference in values makes it necessary to find a more suitable and accurate test method.

The color-changing device in the embodiment of the present application may be an electrochromic device, a photochromic device, a magneto-chromic device, and the like.
One application of the color-changing device or the assembly thereof is on a casing of an electronic device, and the color-changing device or the assembly thereof is used for realizing a color-changing effect of the casing of the electronic device. The electronic device may include a mobile phone, a tablet computer, a notebook computer, a wearable device, etc., which are not listed here. The method for detecting the color change response time of the color change device in the present embodiment includes, but is not limited to, the following steps. It should be noted that, in the flow method in this embodiment, the order of each step does not represent that there is a certain sequential execution relationship, and some steps without a causal relationship may be performed synchronously or sequentially.
The detection method comprises the following steps: and S100, carrying out video shooting on the color changing process of the color changing device.
In step S100, the setup of the whole test hardware architecture is described first. Referring to fig. 2, fig. 2 is a schematic diagram of a hardware architecture of the detection method. The color-changing device 10a and the shooting device 10b (which can be a camera or other electronic equipment with video shooting and recording functions) are placed in a cavity with uniform illumination, and ideally, the cavity is a closed or semi-closed space irradiated by a light source on the periphery. The color-changing device 10a is fixed in position by a limiting clamp 10 c; the shooting device is fixed at a certain proper fixed angle. The color changing device continuously changes color, video recording is continuously carried out, and the recorded video is stored.
In step S100, it is required to complete video shooting of at least one complete color change process of the color change device, and it is ensured that the color change of the color change device in the complete color change process is completely recorded.
The detection method further comprises the following steps: and S200, comparing the color of the color changing device in the color changing process in the video with the standard color.
After completing the video capture of at least one complete color change process of the color changing device in step S100, the step of color comparison is started. The specific process can be to compare the color of the color changing device in the video with the standard color, and the standard color can be a color card or a standard sample.
Optionally, referring to fig. 3, fig. 3 is a schematic front view of a structure in which the limiting fixture is matched with the color-changing device in fig. 2, wherein in the same shooting picture in the previous step, the color-changing device 10a, the first standard sample 10d in the first standard color state, and the second standard sample 10e in the second standard color state may be simultaneously subjected to video shooting. In the embodiment of the present application, an electrochromic device is taken as an example for explanation, because the electrochromic device after being powered on has slow leakage, the comparison samples (10d and 10e, also called as standard samples or golden machines, gold sample) need to be powered again according to a standard procedure at intervals due to this requirement, and this time may be two hours for the comparison sample for the test in this embodiment. The color changing device 10a can be connected with a programmable program control power supply or a workstation as a voltage input to realize color changing of the sample.
When the error range of the color changing device in the color changing process in the video is within +/-5% of the standard color, the color change of the color changing device can be considered to meet the contrast requirement of the standard color.
The detection method further comprises the following steps: step S300, acquiring the time interval of the color in the color changing process of the color changing device corresponding to the first standard color and the second standard color respectively as the color changing response time of the color changing device.
In the step, recording time is started when the color of the color-changing device in the color-changing process corresponds to the first standard color, and the recording time is stopped until the color of the color-changing device is changed to the second standard color, wherein the recorded time is the color-changing response time of the color-changing device.
On one hand, the time corresponding to the two control samples with almost consistent colors (within the error of +/-5%) can be read by manual video card points, and the two times are subtracted to obtain the color change response time value. The method is suitable for temporary testing, and a low-data-volume scene of repeated testing does not exist. In addition, an automatic thinking is established, and the detailed process of the method is described in detail in the following embodiments by setting specific color values and automatically capturing and judging by a program.
The method for detecting the color change response time of the color change device, provided by the embodiment of the application, carries out video shooting through the color change process of the color change device, and then compares the video shooting with a standard color to obtain the color change response time of the color change device. The detection method solves the testing difficulty of the light-tight and uneven light-transmitting color-changing device on one hand, and does not need to test at the semi-finished product stage, thereby improving the production efficiency and the product quality; on the other hand, the situation that a large deviation exists between the measured value and the actual value due to the problem defined by the discoloration response time standard can be avoided. The detection method provided by the application has the characteristics of simple flow and high detection accuracy and reliability.
Referring to fig. 4, fig. 4 is a schematic flow chart of another embodiment of a method for detecting a color change response time of a color change device according to the present application, wherein the method in the present embodiment includes the following steps.
In step S400, color values of the first standard color and the second standard color are recorded.
In this step, the color values corresponding to the two color-changed states of the standard sample may be recorded. The color value may be based on a value on either the a-value channel or the b-value channel on the Lab color model. The Lab coordinate system is actually a color space, L represents brightness, a and b represent two color channels, a is a red-green axis, wherein a + represents red and a-represents green; b is the yellow-blue axis, where b + represents yellow and b-represents blue. Taking the magenta electrochromic device as an example, it achieves a color transition between red and transparent colors, so the change in a-value should be most sensitive. Therefore, if a magenta color-changing device is taken as an example, it is appropriate to use the value a as the color value to be recorded. Of course, in some other embodiments, such as a color-changing device with blue or yellow as the color change, the b-value channel can be used as the selection of the color value.
In addition, the color value may also be the R (Red ) G (Green, Green) B (Blue) value of the recorded sample. Taking the magenta color-changing device as an example, since the sample is converted between magenta and fade, the R value is changed most, and therefore it is appropriate to record the R value. If the color-changing device sample is a color-changing device sample of other colors, the G or B value can be recorded, and the color-changing device sample is not particularly limited.
The detection method further comprises the following steps: and S100, carrying out video shooting on the color changing process of the color changing device. For the detailed process and hardware architecture of step S100, reference may be made to the related description of the foregoing embodiments.
And S200, comparing the color of the color changing device in the color changing process in the video with the standard color. In this step, specifically, the color value of the color in the process of changing the color of the color changing device in the video may be compared with the color value of the standard color.
Step S300, acquiring the time interval of the color in the color changing process of the color changing device corresponding to the first standard color and the second standard color respectively as the color changing response time of the color changing device.
In step S300, the step of acquiring a time interval between the color in the color changing process of the color changing device and the first standard color and the second standard color as the color changing response time of the color changing device may specifically include the following steps. Referring to fig. 5, fig. 5 is a schematic block diagram of a flow of an embodiment of obtaining a time interval between a color in a color changing process of a color changing device and a first standard color and a second standard color as a color changing response time of the color changing device.
And step S310, recording the time when the color of the color-changing device reaches the first standard color in the color-changing process as the initial time.
In this step, the time T0 when the color value of the color in the process of changing the color of the color changing device reaches the color value of the first standard color may be recorded as the initial time. The phrase "close to" or "near to" means that the difference between the color value of the color in the process of changing the color of the color changing device and the color value of the first standard color is within ± 5%, and it is considered that the color value of the color in the process of changing the color of the color changing device has reached the color value of the first standard color.
And step S320, recording the time when the color of the color-changing device reaches the second standard color for the first time after the initial time as the end time.
In step S320, a time T1 when the color value of the color in the process of changing the color of the color changing device reaches the color value of the second standard color for the first time after the initial time is recorded as an end time.
And step S330, calculating the difference value between the end time and the initial time as the color change response time of the color change device.
In this step, the difference T1-T0 between the end time TI and the initial time T0 is the discoloration response time of the color change device.
In the method for detecting the color change response time of the color changing device in the embodiment, the standard color value is set and recorded at the same time, then the color value of the color in the color changing process of the color changing device is automatically identified through a program, the time is recorded, and the color change response time of the color changing device is obtained through calculation; the method has the characteristics of high automation degree and accurate test, and is suitable for tests with large test quantity and high repeatability.
Referring to fig. 6, fig. 6 is a schematic flow chart of another embodiment of a method for detecting a color change response time of a color change device according to the present application, where the method in this embodiment includes, but is not limited to, the following steps.
Step S500, determining whether the color variation range of the color changing device includes the first standard color and the second standard color.
The step aims to screen whether the color-changing device meets the detection requirement or not. Specifically, it may be detected whether the color change range of the color changing device includes the first standard color and the second standard color, that is, whether the color value of the color changing device can respectively reach the color value of the first standard color and the color value of the second standard color in the process of detecting the complete color of the color changing device, if the result of the determination is yes, the next step (S400) is performed, and if not, the step S501 is performed, it is determined that the color changing device does not satisfy the detection requirement, and the subsequent color changing response time detection process will not be performed by the color changing device.
Referring to fig. 6, the detecting method further includes: in step S400, color values of the first standard color and the second standard color are recorded.
As described in the foregoing embodiments, the color values of the first standard color and the second standard color may be based on the a value or the b value of the Lab color model, and may also be RGB values of the recorded sample.
The detection method further comprises the following steps: and S100, carrying out video shooting on the color changing process of the color changing device. And S200, comparing the color of the color changing device in the color changing process in the video with the standard color. In this step, specifically, the color value of the color in the process of changing the color of the color changing device in the video may be compared with the color value of the standard color. The detailed processes and hardware structures of steps S100 and S200 can refer to the related descriptions of the foregoing embodiments, and are not repeated here.
Step S300, acquiring the time interval of the color in the color changing process of the color changing device corresponding to the first standard color and the second standard color respectively as the color changing response time of the color changing device.
In step S300, the step of acquiring a time interval between the color in the color changing process of the color changing device and the first standard color and the second standard color as the color changing response time of the color changing device may specifically include the following steps. Referring to fig. 7, fig. 7 is a schematic block diagram of a flow of another embodiment, in which time intervals between colors in a color changing process of a color changing device and corresponding to a first standard color and a second standard color are obtained as color changing response times of the color changing device.
And step S310, recording the time when the color of the color-changing device reaches the first standard color in the color-changing process as the initial time.
In this step, it is also possible to record the time T0 at which the color value of the color in the process of changing the color of the color changing device reaches the first standard color value as an initial time.
And step S320, recording the time when the color of the color-changing device reaches the second standard color for the first time after the initial time as the end time.
In step S320, a time T1 when the color value of the color in the process of changing the color of the color changing device reaches the color value of the second standard color for the first time after the initial time is recorded as an end time.
And step S340, calculating the difference value between the end time and the initial time as a response time sample of the color-changing device.
In this step, a difference T2(T2 — T1-T0) between the end time TI and the initial time T0 is a response time sample.
Step S350, a plurality of response time samples are repeatedly obtained.
The step of repeating the step S350 to obtain two or more response time samples may specifically be to repeat the steps S310, S320, and S340 and obtain a plurality of response time samples T2.
And step S360, judging whether the maximum difference value between the response time samples is smaller than a preset value.
In this step, it may be specifically determined whether the difference between the maximum value and the minimum value in the plurality of response time samples is smaller than a preset value, for example, the obtained plurality of response time samples T2 are 6s, 6.1s, 6.4s, and 6.5s, respectively; then the difference between the maximum value and the minimum value of the plurality of response time samples T2 is 6.5-6 ═ 0.5s, and it is determined whether the difference of 0.5s is smaller than the preset value. The preset value can be a value of 0.2s, 0.3s, 0.5s, 0.8s, 1s, 2s, 3s, etc., and can be set by a person skilled in the art according to the length of the color-changing response time of the color-changing device and the requirement of the detection precision. In this embodiment, if the preset value is 1S, the determination result is yes (the difference between the maximum value and the minimum value of the response time samples T2 is 0.5S, which is smaller than 1S), and then the next step is performed (S370). If the preset value is 0.3S in some other embodiments, the determination result in this embodiment is yes, and step S361 is entered to determine that the test is invalid. It is indicated that the maximum difference between the response time samples T2 is too large, and the test data cannot meet the preset requirement. The test flow needs to be ended and retested.
In step S370, the color change response time is obtained based on the plurality of response time samples.
In this step, the step of obtaining the discoloration response time based on the plurality of response time samples may specifically be calculating a mean value of the plurality of response time samples as the discoloration response time, or taking a median of the plurality of response time samples as the discoloration response time.
