Detailed Description
In order to better understand the technical scheme of the invention, the invention is further described in detail with reference to the drawings and specific embodiments.
The invention discloses a system and a method for detecting visual comfort degree aiming at watching three-dimensional display content, the system provides a hardware layout, a software system and a detection method required for detecting the visual comfort degree, and the system can simply, quickly and quantitatively measure the visual comfort degree caused by watching the three-dimensional display and carry out result verification based on subjective evaluation.
The invention arranges the experimental equipment in a room with enough space, and the humidity, the temperature and the illumination in the room can all use the ordinary indoor environment state. In order to ensure that the visual state of the user is good, it is recommended that the measurement be scheduled to be performed at nine am and two pm; since prior interviews of subjects indicated that their eyes had just had a better rest during these two periods of time, the visual state was when the day was better. Of course, it may be arranged to take place at other times, provided that the conditions are consistent, or simply for testing purposes.
Experiments require the use of a computer display to display three-dimensional content, including three-dimensional video, transitional pictures, and the like. The display may be various types of three-dimensional displays, such as: red-blue stereoscopic displays, polarized stereoscopic displays, stroboscopic stereoscopic displays, autostereoscopic displays, red-blue stereoscopic projection screens, polarized stereoscopic projection screens, stroboscopic stereoscopic projection screens, autostereoscopic projection screens, and the like. The user sits at a distance from the display and the position and the direction of the user's gaze can be fine-tuned before the measurement starts, so that a suitable viewing distance and angle is obtained. When the display devices such as a red-blue stereoscopic display, a polarized stereoscopic display, a stroboscopic stereoscopic display, a red-blue stereoscopic projection screen, a polarized stereoscopic projection screen, and a stroboscopic stereoscopic projection screen are used for watching, the user needs to wear corresponding red-blue glasses, polarized glasses, or stroboscopic glasses.
In the experiment, an infrared camera is also needed to record the eye picture of the user in the whole watching process; these frames will be subsequently used to extract therefrom the eye movement information of the user, specifically the blink frequency and the eye-closing duration of the user, automatically extracted by the system; this information can be used as an objective index to reflect visual comfort. In order to improve the accuracy of the subsequent processing results, the camera is generally required to have a higher spatial resolution and a higher frame rate.
The infrared illumination required by the infrared camera is provided by an infrared light source. In order to be able to obtain sufficiently sharp images without negatively affecting the eyes of the user, the intensity of the infrared light source should be adjusted to a suitable range.
The subjective scores of the users on the visual comfort level in the watching process are collected through a comfort level subjective scoring device. The using method of the device is similar to the using method of the subjective visual fatigue continuous scoring device in the patent of the visual fatigue detection system and the method of three-dimensional display resources (application number: 201410019363X).
The software system of the invention provides an integrated framework and various running modules for the whole measuring operation, and the architecture diagram of the software system can be divided into three large parts, namely a presentation layer, an application layer and a data layer, as shown in figure 1. When the experiment is carried out by adopting the invention, the treatment process is as follows: firstly, selecting or creating resources (such as transition pictures, stimulation pairs and complete continuous videos) required by experiments; then, organizing and arranging the relative sequence of the resources according to the experiment and the needs, and playing; secondly, collecting subjective scoring data and objective index data simultaneously in the playing process; and finally, the degree, the variation trend and the like of the visual comfort can be known according to the acquired result.
The presentation layer includes two modules: a training presentation module 110 and a viewing content presentation module 120.
The training demonstration module 110 includes an operation procedure demonstration sub-module 111 and an operation procedure practice sub-module 112. The operation process demonstration sub-module 111 plays and demonstrates the complete flow of the measurement operation in the manner of a video tutorial, and after the user carefully watches the demonstration, the user can establish intuitive impression and understanding on the whole measurement process. The course of operation exercise sub-module 112 also plays and demonstrates the method of use of the various instruments in the form of a video tutorial, including: the method of use of the Visual Response Time (VRT) gauge 140 and the maximum adjustment Point (PMA) gauge 160, the specific method of use being demonstrated in accordance with the foregoing operating steps.
The viewing content presentation module 120, in turn, includes a transition picture display sub-module 121 and a stimulus video playback sub-module 122. The transition picture display sub-module 121 is configured to display a preselected transition picture and a stimulus pair, and can display the transition picture and the stimulus pair in different display modes, such as: different display sequences, different time intervals, whether to repeat the display, etc., the transition picture and stimulus pairs are played alternately. The stimulus video playing sub-module 122 is configured to display a preselected stereoscopic video (i.e., a complete continuous video), support multiple stereoscopic video formats, and be capable of switching between left-right, right-left, up-down, down-up, and so on display modes.
The application layer includes a relative comparison module 130 and a continuous viewing module 140.
The relative comparison module 130 further includes a visual stimulation integration sub-module 131 and a relative comfort evaluation sub-module 132. For testing purposes, the visual stimulus integration sub-module 131 integrates every two visual stimuli requiring relative comparison into a stimulus pair (the visual stimuli themselves exist individually, and before the relative comparison, a reference visual stimulus unit is selected from the visual stimuli, and then a plurality of other visual stimuli are selected and combined with the reference visual stimulus unit into a pair, and the relative comparison is performed between each pair of visual stimuli. Each pair of stimuli may be presented in both positive and negative orders, thereby offsetting the effect of the viewing order on the results of the evaluation. The relative comfort assessment sub-module 132 functions to intersperse assessment scores measuring the relative comfort of the user for each pair of visual stimuli in the course of the relative comparisons.
The continuous viewing module 140 in turn comprises a continuous viewing content integration sub-module 141 and a cumulative comfort evaluation sub-module 142.
The continuous viewing content integration sub-module 141 randomly selects from all visual stimuli that require continuous viewing and integrates into a complete video that can be continuously viewed. The cumulative comfort assessment sub-module 142 includes two parts, a questionnaire and a subjective score. Wherein the questionnaires are used at the beginning and end of the measurement, corresponding to the pre-view questionnaire and the post-view questionnaire, respectively. The main contents of the two questionnaires are the same, but the questionnaire before watching additionally collects personal information of the user such as name, sex, eyesight and the like, and the rest contents are all specific subjective measurement indexes aiming at the visual comfort level. The questionnaire body content can have different forms, one of which contains 15 different symptoms for which the user can give different scores of 1-5. Other questionnaires of the same type, as well as different scoring rules, such as a nine point system, etc., may also be used in a particular application. The cumulative comfort evaluation sub-module 142 is used in combination with the visual comfort subjective scoring device, reads the score data collected by the device, and stores the score data in a memory according to a predetermined format.
The data I/O module 150 is used to read or write data from or to the data storage unit. The data storage unit may be a file, a database, or the like. Data used in the measurement process include: relative comfort 151, the relative comfort score between pairs of visual stimuli measured in a relative comparison segment; continuous comfort 152, i.e., questionnaire information and subjective rating scores collected during the continuous viewing session.
The operation flow corresponding to the relative comparison module 130 is shown in fig. 2. Prior to the first round of comparison, a 3 second medium gray scale screen was first presented and the experiment was prompted to begin. In each subsequent comparison, two excitations to be compared appear in sequence, the middle is separated by a middle gray scale picture, and the time duration is 3 seconds; after the second excitation is finished, the middle gray scale picture is presented again for 7 seconds, and the tested object is prompted to input a comparison result. And then, performing the next round until the comparison of the last round is finished, displaying the middle gray level picture again and prompting the end. The subject should naturally watch a target area in the screen when viewing, and should evaluate discomfort in visual sense, not psychological sense, etc.
In the relative comparison module 130, the comparison result is Relative Comfort (RC). Representing the relative comfort of the previous stimulus versus the next stimulus for each stimulus pair over the range shown in figure 3. From-3 to 3 points, the corresponding relative comfort degrees of the previous video to be watched are much worse, slightly worse, the same, slightly better, much better and much better than the next video.
As shown in fig. 4, the continuous viewing content integration sub-module 141 integrates a continuous viewing video with a video set of two large segments as main content. The contents of the two partial videos are the same, and the difference is that one is a stereo video and the other is a flat video. When the first presented is a stereo video, the subsequent presented is a plane video; on the contrary, when the planar video is presented first, the stereoscopic video is presented subsequently. The two segments of video can be formed by connecting a plurality of shorter videos in sequence. In addition to the two large segments of video, three transitional pictures are integrated into the entire video. The three transitional videos are all a black round dot in the center of a pure gray background, the function of the black round dot is to provide a watching target for an observer, and the movement of eyes can be recorded by an infrared camera during the time of watching the transitional videos, so that objective measurement indexes are provided for subsequent analysis. In this experiment, transition videos appear at the beginning, middle, and end of the entire video, respectively. In which the transition video appearing in the middle appears exactly between the above-mentioned stereoscopic video and the flat video.
The operation flow corresponding to the continuous viewing module 140 is shown in fig. 5. The tested person needs to watch a section of video short film first, and practice scoring in the watching process; the purpose of this link is to make the subject familiar with the experimental rules, and adapt to the way of scoring while watching; the video clips viewed at this time are different from those viewed formally from the rear. After the practice is finished, the tested person needs to fill in an initial questionnaire; during filling, the main test explains the meaning of the clear question for the tested piece by piece. The questionnaire was used to collect some personal information of the subject and to evaluate visual comfort and discomfort symptoms at that time as a basis for the experiment. And then, starting the infrared camera to collect the eye images, and simultaneously trying to continuously watch the excitation video. When the comfort degree changes in the watching process, the mark is scored immediately, and a prompt tone is sounded every 1 minute so as to avoid that the mark is forgotten by the test. After the video viewing is completed, the camera is stopped, and the subject is tested to evaluate the visual comfort, the stereoscopic impression, etc. through a summary questionnaire, and to give some opinions (if any) to the experiment itself. The video watched in the process consists of visual stimulation resources with different characteristics, and different influences of different resources on the visual comfort level are detected through the visual comfort levels in different stages.
In the continuous viewing module 140, the observer gives a corresponding score to the visual comfort at each moment while continuously viewing. All possible scores are shown in fig. 6. From 1 to 5 points, which indicate very uncomfortable, slightly uncomfortable, comfortable, very comfortable, respectively.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
