Description

Display effect evaluation method and device of three-dimensional display device and evaluation terminal

Technical Field

The invention relates to the field of naked eye three-dimensional display, in particular to a display effect evaluation method and device of a three-dimensional display device and an evaluation terminal.

Background

With the development of image display technology, naked eye stereoscopic display devices are increasingly widely used. The naked eye stereoscopic technology can enable audiences to obtain high-fidelity stereoscopic experience without wearing any auxiliary visual tool, and compared with the existing two-dimensional display technology or the stereoscopic display technology realized by a three-dimensional display device wearing the visual tool, the naked eye stereoscopic display has better user experience.

However, the quality requirement of naked eye stereoscopic display on image display is very high, the existing stereoscopic display equipment lacks complete and comprehensive stereoscopic display effect detection, and the standardized evaluation research on the key parameters of the naked eye stereoscopic display is relatively delayed, so that the quality and the visual effect of the naked eye stereoscopic products at the present stage are not uniform. For example, in the autostereoscopic display, left and right eye images are separately displayed on a display, and then are respectively matched to two eyes of a viewer. When the matching is damaged, the left and right eye images are mistakenly transmitted, and crosstalk is generated. The crosstalk rate is used as the most important evaluation index of the stereo display technology, and more than half of audiences can generate visual discomfort when reaching 5 percent; if the crosstalk ratio exceeds 10%, a case where the stereoscopic image is difficult to be merged in the brain of the viewer occurs.

Therefore, how to more conveniently and accurately evaluate the display effect and the crosstalk degree of the stereoscopic display is an urgent problem to be solved in the current evaluation of the stereoscopic display, so that the quality of a naked eye stereoscopic display product is better standardized, and the technical development of the naked eye stereoscopic display product is promoted.

The existing evaluation method comprises the following steps: on a set fixed point, a single camera is used for shooting red and green stripes with a specific rule on a screen, and the result of qualification or non-qualification is given by analyzing the definition degree of a red and green boundary and whether the boundary is a straight line or not and the purity of red and green.

However, this method is only suitable for evaluating the effect of a small-sized stereoscopic whole device, the large-sized 3D display module is affected by the problems of size and equipment precision, and the flatness and uniformity are much lower than those of the small-sized stereoscopic module.

Therefore, the existing naked eye display device testing technology still needs to be improved and developed.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The method for evaluating the display effect of the stereoscopic display device is used for evaluating the stereoscopic display effect of the stereoscopic display device, and is a method for simulating eyes of a viewer by using an image acquisition device, namely simulating the viewer to watch, acquiring stereoscopic evaluation pictures displayed by the stereoscopic display device to be evaluated at least two preset space test positions according to at least two preset space postures to obtain an evaluation view, and evaluating the display effect of the stereoscopic display device based on all the evaluation views acquired by the image acquisition device. The image acquisition device simulates human eyes of a viewer, and the obtained view can represent the visual perception of the viewer at different viewing positions and different viewing postures, namely represents the stereoscopic display effect of the stereoscopic display device aiming at different viewing positions and different viewing postures, so that the acquired view at different viewing positions and different viewing postures can be comprehensively utilized, the naked eye stereoscopic display overall effect including key indexes such as crosstalk rate, color purity and the like and presented by the stereoscopic display device corresponding to different viewing postures and different viewing positions can be accurately evaluated, and the obtained evaluation result is more accurate and comprehensive.

The method, the device and the terminal for evaluating the display effect of the stereoscopic display device provided by the embodiment of the invention are not limited by the specific structure and the process precision of the stereoscopic display device when the stereoscopic display effect of the stereoscopic display device is evaluated, and can be suitable for naked eye stereoscopic display devices of any types and sizes, and are particularly suitable for stereoscopic display devices with a viewing position tracking function. The viewing position tracking function means that the stereoscopic display device can track the viewing position of a viewer in real time, for example, face tracking is performed on the viewer to determine a face feature position as the viewing position of the viewer, and then left-eye views and right-eye views (namely, an arrangement diagram) are arranged on the display panel according to the viewing position to perform naked-eye stereoscopic display. For the viewing position tracking function and the arrangement, reference is made in detail to the prior art and will not be described in detail here.

The embodiments of the present invention will be further explained with reference to the drawings.

Fig. 1 is a schematic flow chart of a method for evaluating a display effect of a stereoscopic display device according to an embodiment of the present invention, referring to fig. 1, the method includes, but is not limited to, the following steps:

step 110: and acquiring a spatial attitude stereoscopic display effect evaluation view acquired by the image acquisition device.

In this embodiment, the "image capturing device" may be any device capable of simulating human eyes to capture images of a stereoscopic picture presented by a stereoscopic display device, for example, two cameras capable of controlled movement, i.e. left and right binocular cameras, generally include a left eye image capturing device and a right eye image capturing device.

The "spatial attitude stereoscopic display effect evaluation view" is an evaluation view displayed by the stereoscopic display device and acquired by the image acquisition device at a predetermined spatial test position according to a predetermined spatial attitude, and includes a left view and a right view, i.e., a left eye view and a right eye view.

The three-dimensional display device carries out three-dimensional display on the evaluation view, and the image acquisition device acquires the evaluation view according to a preset space posture at a preset space test position to obtain the evaluation view with the three-dimensional display effect of the space posture.

In the stereoscopic display device having the tracking function, the viewing position of the viewer is tracked during the stereoscopic display, that is, the positions of both eyes of the viewer are determined, and the stereoscopic display is performed based on the positions of both eyes. In the embodiment of the invention, the stereoscopic display device may track position information of the image acquisition device (i.e., position information of the predetermined spatial test position), present the evaluation view based on the tracked position information, and acquire the evaluation view according to a predetermined spatial posture at the predetermined spatial test position by the image acquisition device to obtain the spatial posture stereoscopic display effect evaluation view.

Namely, the test view presented by the stereo display device and the spatial attitude stereo display effect evaluation view collected by the image collection device have a corresponding relationship.

For example, when the image capturing device moves to a predetermined spatial test position, the stereoscopic display device outputs a stereoscopic display image corresponding to the predetermined spatial test position, and at this time, the left image capturing device and the right image capturing device respectively capture a left view of the stereoscopic display image and a right view of the stereoscopic display image according to a predetermined spatial posture. In the present embodiment, the "stereoscopic display screen", "left view of the stereoscopic display screen", and "right view of the stereoscopic display screen" are each referred to as a spatial-attitude stereoscopic display effect evaluation view.

In order to simulate the effect of different viewing positions (i.e. different spatial test positions) on the stereoscopic display effect of the stereoscopic display device, in the embodiment, the predetermined spatial test positions include at least two. The "predetermined spatial test position" may be set according to a viewing position of a user when the stereoscopic display device is actually used.

In order to simulate the stereoscopic display effect of the stereoscopic display device presented for different spatial observation postures, in the embodiment, the predetermined spatial postures include at least two kinds. In practical applications, the predetermined spatial attitude may be set including, but not limited to:

a front view gesture for simulating a gesture in which a user is viewing a display screen of the stereoscopic display device;

the head twisting gesture is used for simulating the gesture of watching the user after the head of the user rotates by taking the vertical direction as an axis;

and a head-off posture for simulating a posture of the user's head viewed after rotating about an axis perpendicular to the display screen.

In this embodiment, the image capturing device may be first controlled to capture a spatial posture stereoscopic display effect evaluation view at each predetermined spatial test position in a front-view posture, a head-twisted posture and a head-skewed posture respectively (that is, the spatial posture stereoscopic display effect evaluation view corresponding to the front-view posture, the head-twisted posture and the head-skewed posture is obtained at each predetermined spatial position); and then, the spatial attitude stereoscopic display effect evaluation view acquired by the image acquisition device is sent to an evaluation terminal, and the evaluation terminal executes the following steps 120 to 130 based on the spatial attitude stereoscopic display effect evaluation views.

Step 120: and acquiring a spatial attitude stereoscopic display effect evaluation value of the stereoscopic display device according to the spatial attitude stereoscopic display effect evaluation view.

In this embodiment, after the spatial posture stereoscopic display effect evaluation views are acquired, the spatial posture stereoscopic display effect evaluation views are analyzed, and a numerical value for evaluating the stereoscopic display effect of the stereoscopic display device, which is the spatial posture stereoscopic display effect evaluation value of the stereoscopic display device, is obtained by integrating all analysis results.

Specifically, in one embodiment, a specific implementation manner of obtaining the spatial posture stereoscopic display effect evaluation value of the stereoscopic display device according to the spatial posture stereoscopic display effect evaluation view may be as shown in fig. 2, which includes, but is not limited to, the following steps:

step 121: and obtaining a three-dimensional display effect evaluation value corresponding to each preset space test position under each preset space posture according to the three-dimensional display effect evaluation view of each preset space test position under each preset space posture.

In this embodiment, any one or more attributes of the stereoscopic display effect may be selected to evaluate the stereoscopic display device, for example, the stereoscopic display device may be evaluated based on any one or more attributes of brightness, contrast, color temperature, color gamut, color purity, crosstalk, and the like. And correspondingly presenting different spatial attitude stereoscopic display effect evaluation views by the stereoscopic display device corresponding to the selected different attributes, and analyzing the acquired spatial attitude stereoscopic display effect evaluation views by the evaluation terminal correspondingly by adopting different analysis methods.

Among the attributes of the stereoscopic display effect, color purity and crosstalk are the most critical factors affecting the stereoscopic display effect, so in this embodiment, the color purity and crosstalk can be selected as the criteria for evaluating the stereoscopic display effect of the stereoscopic display device. At this time, the stereoscopic display device correspondingly presents a spatial posture stereoscopic display effect evaluation view for analyzing color purity and crosstalk, for example, after the stereoscopic display device determines the position information of the image acquisition device, a stereoscopic display picture (for example, a left-red-right-green stereoscopic display picture) including two colors is presented based on the position information, and the left image acquisition device acquires a picture (for example, a full-red picture) of one color and the right image acquisition device acquires a picture (for example, a full-green picture) of the other color, so that the evaluation terminal performs color purity analysis and crosstalk analysis based on the two acquired single-color pictures (for example, the full-red picture and the full-green picture) which are respectively independent.

Based on this, the specific implementation of this step 121 may be:

(1) and carrying out color purity detection and crosstalk detection on the left view and the right view of the spatial attitude stereoscopic display effect evaluation view at each preset spatial test position under each preset spatial attitude, and acquiring color purity analysis values and crosstalk analysis values of the left view and the right view.

In this embodiment, when obtaining the color purity analysis value and the crosstalk analysis value of the left view and the right view, it is necessary to first determine an analysis region of the left view and an analysis region of the right view. The analysis area is an effective area of the evaluation view displayed by the stereoscopic display device in the spatial posture stereoscopic display effect evaluation view acquired by the image acquisition device.

Therefore, in this embodiment, the specific implementation manner of performing color purity detection and crosstalk detection on the left view and the right view of the spatial posture stereoscopic display effect evaluation view at each predetermined spatial test position in each predetermined spatial posture to obtain the color purity analysis value and the crosstalk analysis value of the left view and the right view may be as follows:

for the left view: firstly, determining an analysis area of a left view, then detecting color component values of dominant colors and color component values of crosstalk colors of all pixel points in the analysis area, and finally determining a color purity analysis value and a crosstalk analysis value of the left view according to the detected color component values of the dominant colors and the color component values of the crosstalk colors by the following formulas:

wherein the content of the first and second substances,

representing the color purity analysis value of the left view of the jth predetermined spatial test position in the kth predetermined spatial pose,

a crosstalk analysis value representing a left view of a jth predetermined spatial test position at a kth predetermined spatial attitude; w^LWidth of the analysis area for left view, H^LAnalyzing the height of the region for the left view, C^LFor dominant colours of individual pixels in the left view analysis regionColor component value, ∑ C^LThe sum of the color components of the dominant colors of all the pixel points in the left view analysis region, M^LColor component values, sigma M, of crosstalk colors of individual pixel points in the left view analysis region^LAnd the sum of the color components of the crosstalk colors of all the pixel points in the left view analysis area is obtained.

For the right view: firstly, determining an analysis area of the right view, then detecting the color component value of the dominant color and the color component value of the crosstalk color of each pixel point in the analysis area, and finally determining the color purity analysis value and the crosstalk analysis value of the right view according to the detected color component values of the dominant color and the crosstalk color through the following formulas:

wherein the content of the first and second substances,

representing a color purity analysis value of a right view of a jth predetermined spatial test position in a kth predetermined spatial pose,

a crosstalk analysis value, W, representing a right view of a jth predetermined spatial test position in a kth predetermined spatial pose^RWidth of the analysis area for the right view, H^RAnalyzing the height of the region for the right view, C^RColor component values, Σ C, of the dominant colors of a single pixel in the right view analysis region^RThe sum of the color components of the dominant colors of all the pixel points in the right view analysis region, M^RColor component values, sigma M, of crosstalk colors of individual pixel points in the right view analysis region^RAnd the sum of the color components of the crosstalk colors of all the pixel points in the right view analysis area is obtained.

Note that, in the present embodiment, the width (W) of the analysis region^LAnd W^R) And height (H)^LAnd H^R) Are values of pixel space (e.g., W)^LRepresenting left view analysis area in widthThe number of upward pixels), and the color component value of the dominant color is the highest value (255) by default in the most ideal state, and the color component value of the crosstalk color is the highest value (255) by default in the worst state.

Therefore, in this embodiment, the color purity analysis value of the left view/right view can be obtained by directly comparing the actually obtained color component sum of the dominant color in the left view/right view with the default color component value sum of the dominant color in the optimal state; and directly comparing the actually acquired color component sum of the crosstalk colors in the left view/the right view with the color component sum of the crosstalk colors in the default worst state to obtain the crosstalk analysis value of the left view/the right view.

Or, in other embodiments, in order to improve the detection accuracy, another implementation may also be used to perform color purity detection and crosstalk detection on the left view and the right view of the spatial posture stereoscopic display effect evaluation view at each predetermined spatial test position in each predetermined spatial posture, so as to obtain a color purity analysis value and a crosstalk analysis value of the left view and the right view. This embodiment differs from the above embodiment in that: in this embodiment, the color purity analysis value and the crosstalk analysis value of the left view are determined by the following formulas:

wherein, C^LColor component value, Σ C, of a dominant color of a single pixel in a left view analysis region^LThe sum of the color components of the dominant colors of all the pixel points in the left view analysis region, M^LColor component values, sigma M, of crosstalk colors of individual pixel points in the left view analysis region^LThe sum of color components of crosstalk colors of all pixel points in the left view analysis area is obtained;

analyzing a color component reference value of a dominant color of a single pixel point in the area for the left view;

the sum of the reference values of the color components of the dominant colors of all the pixel points in the left view analysis area is obtained;

analyzing a color component reference value of crosstalk colors of a single pixel point in the area for the left view;

and the sum of the reference values of the color components of the crosstalk colors of all the pixel points in the left view analysis area is obtained.

And the number of the first and second groups,

determining a color purity analysis value and a crosstalk analysis value of the right view by the following formulas:

wherein, C^RColor component values, Σ C, of the dominant colors of a single pixel in the right view analysis region^RThe sum of the color components of the dominant colors of all the pixel points in the right view analysis region, M^RColor component values, sigma M, of crosstalk colors of individual pixel points in the right view analysis region^RThe sum of color components of crosstalk colors of all pixel points in the right view analysis area is obtained;

a color component reference value of a dominant color of a single pixel point for the right view analysis region,

the sum of the color component reference values of the dominant colors of all the pixel points in the right view analysis region,

a color component reference value of crosstalk color for a single pixel point of the right view analysis region,

and the sum of the reference values of the color components of the crosstalk colors of all the pixel points in the right view analysis area is obtained.

In this embodiment mode, the "color component reference value"

The color component value of a single color at a single pixel point in the left view/right view collected by the image collection device is measured when the evaluation view presented by the stereoscopic display device is a single-color picture. Therefore, it can be understood that, in order to implement this embodiment, when the image capturing device is moved to a certain predetermined spatial test position, the stereoscopic display device independently presents a stereoscopic display picture including only one of the two colors in addition to a stereoscopic display picture including two colors, respectively, so that the left and right image capturing devices acquire a left view and a right view for analyzing the color component reference value.

In this embodiment, the color purity analysis value of the left/right view is obtained by comparing the sum of the color components of the dominant color in the left/right view that is actually obtained with the sum of the color component reference values of the dominant color that is actually obtained; and comparing the color component sum of the crosstalk color in the actually acquired left view/right view with the color component reference value sum of the actually acquired crosstalk color to acquire a crosstalk analysis value of the left view/right view, so that the detection precision can be improved.

In addition, in the above embodiment, for the left view, the "dominant color" is the color of the picture acquired by the left image acquisition device in an ideal state, and the "crosstalk color" is the color of the picture acquired by the right image acquisition device in an ideal state; for the right view, the "dominant color" is the color of the picture acquired by the right image acquisition device in the ideal state, and the "crosstalk color" is the color of the picture acquired by the left image acquisition device in the ideal state. For example, in an ideal state, the left image acquisition device acquires a full red picture, and the right image acquisition device acquires a full green picture, so that the dominant color of the left view is red, and the crosstalk color is green; but for the right view, the dominant color is green and the crosstalk color is red.

(2) And obtaining the stereoscopic display effect evaluation value of the left view according to the color purity analysis value and the crosstalk analysis value of the left view by the following formula:

wherein the content of the first and second substances,

and (3) representing the stereoscopic display effect evaluation value of the left view of the jth preset space test position under the kth preset space posture.

(3) And obtaining the stereoscopic display effect evaluation value of the right view according to the color purity analysis value and the crosstalk analysis value of the right view through the following formula:

wherein the content of the first and second substances,

(4) And according to the three-dimensional display effect measurement and evaluation value of the left view and the three-dimensional display effect measurement and evaluation value of the right view, obtaining the three-dimensional display effect measurement and evaluation value corresponding to the preset space test position under the preset space posture to which the left view and the right view belong through the following formula:

wherein, B_kjAnd the three-dimensional display effect evaluation value corresponding to the j preset space test position under the k preset space posture is represented.

Step 122: and obtaining the three-dimensional display effect test and evaluation value corresponding to each preset space posture according to the three-dimensional display effect test and evaluation value corresponding to each preset space test position under each preset space posture.

In this embodiment, the stereoscopic display effect evaluation value B corresponding to each predetermined spatial test position in each predetermined spatial posture is obtained_kjThen, according to the three-dimensional display effect evaluation values, a three-dimensional display effect evaluation value corresponding to each predetermined spatial posture is obtained, and the specific implementation manner may be: and accumulating the three-dimensional display effect measurement and evaluation values corresponding to the same preset spatial posture to obtain the three-dimensional display effect measurement and evaluation value corresponding to the preset spatial posture.

Or, considering that different predetermined spatial test positions have different influences on the stereoscopic display effect, in order to make the evaluation result more fit to the actual application scene, in some embodiments, the stereoscopic display effect evaluation value corresponding to each predetermined spatial posture may also be obtained through the following formula:

wherein S is_kRepresenting the stereo display effect evaluation value corresponding to the k-th preset space posture, j representing the preset space test position, m test positions in total, b_kjAnd the influence factor corresponding to the jth preset space test position under the kth preset space posture is represented and used for representing the sensitivity of the corresponding preset space test position to the evaluation result of the stereoscopic display effect.

Wherein, b_kjThe value of (a) can be set according to the influence degree of the preset space test position corresponding to the space test position on the viewing experience of the viewer, and if the viewer pays attention to the viewing experience at one or more space test positions, a larger influence factor can be configured for the space test position.

Step 123: and obtaining the spatial attitude stereoscopic display effect measurement and evaluation value of the stereoscopic display device according to the stereoscopic display effect measurement and evaluation value corresponding to each preset spatial attitude.

In this embodiment, the spatial posture stereoscopic display effect evaluation value of the stereoscopic display device may be obtained by the following formula:

wherein S1 represents the spatial attitude stereoscopic display effect evaluation value of the stereoscopic display device, k represents the predetermined spatial attitude, n predetermined spatial attitudes are provided, a_kAnd representing the influence factor corresponding to the k-th preset space attitude, and being used for representing the sensitivity of the corresponding space attitude to the evaluation result of the stereoscopic display effect.

In this embodiment, the adopted spatial gestures may include a front-view gesture, a head-twisting gesture, and a head-tilting gesture, wherein, since the viewer mostly views the stereoscopic display device in the front-view gesture, the stereoscopic display effect evaluation value obtained based on the front-view gesture has a large influence on the evaluation result (i.e., the front-view gesture has a large sensitivity to the evaluation result of the stereoscopic display effect); the head-twisting posture and the head-tilting posture belong to accidental watching postures, so that the influence of the stereoscopic display effect evaluation value obtained under the head-twisting posture and the head-tilting posture on the evaluation result is relatively small (namely, the sensitivity of the head-twisting posture and the head-tilting posture on the evaluation result of the stereoscopic display effect is small). Thus, in some embodiments, a may be set according to the sensitivity of the three to the evaluation result₁＝2a₂＝2a₃Wherein a is₁Representing the frontal attitude influence factor, a₂Representing the head-twist attitude influence factor, a₃Representing the head-off attitude impact factor.

Step 130: and determining the evaluation level of the stereoscopic display effect of the stereoscopic display device according to the evaluation value of the stereoscopic display effect of the spatial attitude of the stereoscopic display device.

In this embodiment, a corresponding relationship between the threshold ranges of the stereoscopic display effect evaluation values of different spatial attitudes and the evaluation levels may be pre-established, and when the stereoscopic display effect evaluation value of the stereoscopic display device is obtained, the evaluation level of the stereoscopic display effect of the stereoscopic display device may be determined by comparing the corresponding relationship with the threshold ranges of the stereoscopic display effect evaluation values of different spatial attitudes.

In order to facilitate detection, a first threshold may be set, and when the evaluation value of the stereoscopic display effect of the spatial attitude of the stereoscopic display device is greater than the first threshold, the evaluation level of the stereoscopic display effect of the stereoscopic display device is determined to be the first level. The first threshold may be set according to an actual application scenario or an empirical parameter, and the first level may be "pass". For example, when the evaluation value of the stereoscopic display effect of the spatial posture of the stereoscopic display device is greater than 0.8, the evaluation level of the stereoscopic display effect of the stereoscopic display device is determined to be passed.

Of course, it is understood that, in practical applications, any number of evaluation levels may be divided according to other suitable manners, and the embodiment of the present invention is not limited in this respect.

According to the technical scheme, the method for evaluating the display effect of the stereoscopic display device provided by the embodiment of the invention has the beneficial effects that: the naked eye stereoscopic display overall effect of key indexes including crosstalk rate, color purity and the like, which are presented by the stereoscopic display device corresponding to different viewing postures and different viewing positions, can be accurately evaluated, and the evaluation result is more accurate and comprehensive.

Further, in order to evaluate the tracking speed and the tailing effect of the stereoscopic display device, another method for evaluating the display effect of the stereoscopic display device is provided in the embodiments of the present invention, please refer to fig. 3, which includes, but is not limited to, the following steps:

Wherein 5(0,0,0) is the central space test position (origin); and the influence factors corresponding to the space test positions are respectively as follows: b_k1、b_k2、b_k3、b_k4、b_k5、b_k6、b_k7、b_k8And b_k9B can be set according to the sensitivity of each space test position to the evaluation result_k1：b_k2：b_k3：b_k4：b_k5：b_k6：b_k7：b_k8：b_k94: 7: 4: 5: 10: 5: 4: 7: 4. meanwhile, it is assumed that the preset spatial postures include k ═ 1 (indicating an orthographic posture), k ═ 2 (indicating a twisted head posture), and k ═ 3 (indicating an off-head posture), and the influence factors corresponding to these preset spatial postures are: a is₁、a₂And a₃A can be set according to the sensitivity of each space posture to the evaluation result₁＝2a₂＝2a₃。

In the implementation process, the control box 20 may control the posture moving device 42 to adjust the spatial posture of the image collecting device 41 to the front view posture according to the control instruction issued by the evaluation terminal 30, and control the spatial moving device 43 to move the image collecting device 41 to the position 1(-200,0, 200); meanwhile, the stereoscopic display device 10 is controlled to continuously track the position information of the image acquisition device, and the presented evaluation view is updated in real time according to the position information of the image acquisition device 41. When the image pickup device 41 moves to the position 1(-200,0,200), the stereoscopic display device 10 performs stereoscopic display according to the position information; the image capturing device 41 captures the evaluation view displayed by the stereoscopic display device 10 in the front view posture, thereby obtaining an evaluation view at a position 1(-200,0,200) in the front view posture (i.e., a spatial posture stereoscopic display effect evaluation view). Subsequently, the control box 20 continues to control the spatial motion device 43 to move the image capturing device 41 to the position 2(0, 200), and capture the spatial posture stereoscopic display effect evaluation views at the position 2(0, 200) according to the front-view posture, and so on until the spatial posture stereoscopic display effect evaluation views at all the predetermined spatial test positions under all the predetermined spatial postures are obtained, and send the spatial posture stereoscopic display effect evaluation views (including 27 left views and 27 right views) to the evaluation terminal 30 for analysis.
