Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The invention relates to a method for measuring the virtual scene field angle of a virtual display device, which uses a human eye simulating optical system (CN201911385482.6) to image a virtual scene instead of actual human eyes. The center of the entrance pupil diaphragm of the human eye-imitating optical system is close to the center of the exit pupil diaphragm of the virtual display device. Measuring the depth of the virtual scene by moving the position of the human eye-imitating optical system sensor; meanwhile, the optical axis of the human eye-imitating optical system can horizontally and vertically rotate around the center of the entrance pupil diaphragm along the main axis, so that the horizontal field angle and the vertical field angle of the virtual scene are quantitatively measured, and the quantitative analysis of the display effect of the virtual display equipment is realized.
The quantitative analysis of the display effect of the virtual display device is divided into two parts, wherein the first part is the measurement of the depth of the virtual scene, and the second part is the measurement of the field angle of the virtual scene.
A first part: the principle of virtual scene depth measurement is shown in fig. 1, and the virtual display device display screen 2, the virtual display device optical system 3, the virtual display device exit pupil diaphragm 4, the human eye-imitating optical system entrance pupil diaphragm 5, the human eye-imitating optical system 6 and the human eye-imitating optical system sensor 7 (i.e. the imaging plane of the virtual scene) related to the measurement system of the present invention are arranged from left to right. Where l1 denotes the object-side distance of the virtual scene 1 (i.e. the virtual scene) to the eye-mimicking optical system and l1' denotes the distance of the eye-mimicking optical system sensor plane 7 to the eye-mimicking optical system. In fig. 1, the virtual display device optical system 3 and the eye-mimicking optical system 6 are simplified and represented by a thin lens. The virtual display device display screen 2 is located within one-time focal length of the virtual display device optical system 3, and a scene on the virtual display device display screen 2 forms an enlarged scene virtual image 1 in a far place. The center of the virtual display device exit pupil stop 4 is close to (here shown as coinciding with) the center of the humanoid eye optical system entrance pupil stop 5, and the diameter of the humanoid eye optical system entrance pupil stop 5 can be adjusted within the human eye pupil size range (2 mm-10 mm).
The depth of the virtual scene is measured by adopting a method of moving an eye-imitating optical system sensor, and the depth of the virtual scene is measured according to a Gaussian object-image relation
Wherein l is the object space distance, l 'is the image space distance, and f' is the effective focal length of the human eye-imitating optical system. For this virtual scene depth measurement system, f 'and l' can be considered known, in turn, from
L can be obtained.
Axially moving the position of the eye-simulating optical system sensor, detecting the definition of the image plane image at the position l ', finding out the clearest position of the image plane image, and recording the image space distance l1' at the moment
The depth l1 of the virtual scene 1 is determined. As shown in figure 1, supposing that the virtual plane 1 corresponds to the human eye-imitating optical system sensor 7, the definition of the image formed by the virtual plane 1 at the human eye-imitating optical system sensor 7 is higher than the definition of the image plane at other axial positions, and by utilizing the characteristic, the depth of the virtual scene of the virtual display equipment can be quantitatively measured, the depth of the virtual scene can be measured by moving the position of the image plane of the human eye-imitating optical system, the display performance of the virtual display equipment can be quantitatively analyzed, and the problem that the virtual scene can only be roughly evaluated by the subjective feeling of people in the past is solvedThe display performance of the virtual display device is presented intuitively due to the problem of the display performance of the virtual display device.
A second part: the core idea of virtual scene field angle measurement is to perform horizontal rotation and vertical rotation on an eye-imitated optical system around the center of a diaphragm of the eye-imitated optical system, and obtain the horizontal field angle and the vertical field angle of a virtual scene plane through a geometric relationship by recording the horizontal rotation angle and the vertical rotation angle. The method comprises the following specific steps:
a virtual display device display screen 2, a virtual display device optical system 3, a virtual display device exit pupil diaphragm 4, a human eye-imitating optical system entrance pupil diaphragm 5, a human eye-imitating optical system 6 and a human eye-imitating optical system sensor 7 are sequentially arranged;
the virtual display device display screen 2 is located within one-time focal length of the virtual display device optical system 3, and a scene on the virtual display device display screen 2 is imaged through the virtual display device optical system 3 to form an upright enlarged scene virtual image 1 (virtual scene); the virtual scene image 1 is imaged on an eye-imitating optical system sensor 7 through an eye-imitating optical system 6;
and 2, coinciding the center of an exit pupil diaphragm 4 of the virtual display device with the center of an entrance pupil diaphragm 5 of an eye-imitating optical system 6, when measuring the horizontal field angle of the virtual scene, horizontally rotating the eye-imitating optical system around the center of the diaphragm, wherein the starting position of the horizontal rotation is shown in fig. 2, the thick line in fig. 2 represents the optical axis of the eye-imitating optical system, the arrangement mode of each element is the same as that in fig. 1, and the same reference numerals represent the same elements. Where α h is a horizontal field angle (known) of the human eye-imitating optical system, θ h is a horizontal field angle (to be measured) of the virtual scene, where α h < θ h, when the human eye-imitating optical system is located at a horizontal field angle measurement rotation start position, half of the virtual scene and half of the non-virtual scene appear on the human eye-imitating optical system sensor 7, and a boundary between the two is located at a central position of the horizontal field angle of the human eye-imitating optical system.
In the process of horizontal rotation, 3 critical conditions can be used as the mark of the end of horizontal rotation, namely the end point of horizontal rotation.
The first critical situation is that the eye-imitating optical system sensor 7 is exactly a virtual scene, as shown in fig. 3, and if the rotation angle is further increased, a non-virtual scene appears on the eye-imitating optical system sensor 7 (before that, because α h < θ h, only a virtual scene exists on the eye-imitating optical system sensor 7), and by using this feature, the rotation angle Δ h1 at this time can be recorded by observing the change of the eye-imitating optical system sensor 7, and θ h ═ α h/2 +/Δ h1 can be easily known from the geometric relationship in fig. 3.
In the case of the 2 nd critical situation, half of the virtual scene and half of the non-virtual scene appear on the eye-imitating optical system sensor 7 again, as shown in fig. 4, the boundary between the virtual scene and the non-virtual scene is again located at the center of the horizontal field of view of the eye-imitating optical system, and by using this feature, the rotation angle Δ h2 at this time can be recorded by observing the change of the eye-imitating optical system sensor 7, and θ h ═ Δ h2 is easily known from the geometric relationship in fig. 4.
The 3 rd critical situation is that all the virtual scenes are not observed on the human eye-imitating optical system sensor 7, as shown in fig. 5, and the virtual scenes are not observed on the human eye-imitating optical system sensor 7, so that by using this feature, a person can record the rotation angle Δ h3 by observing the change of the human eye-imitating optical system sensor 7, and θ h ═ Δ h3- α h/2 is easily known from the geometric relationship in fig. 5.
Thus, all of the above 3 rotation end points can be used to obtain the horizontal field angle of the virtual scene.
When the vertical field angle of the virtual scene is measured, the human eye-imitating optical system vertically rotates around the center of the diaphragm, the starting position of the vertical rotation is shown in fig. 6, the thick line in fig. 6 represents the optical axis of the human eye-imitating optical system, the arrangement mode of each element is the same as that in fig. 1, and the same reference numerals represent the same elements. Where α v is a vertical field angle (known) of the human eye-imitating optical system, θ v is a vertical field angle (to be measured) of the virtual scene, where α v < θ v, when the human eye-imitating optical system is located at a vertical field angle measurement rotation start position, half of the virtual scene and half of the non-virtual scene appear on the human eye-imitating optical system sensor 7, and a boundary line between the two is located at a central position of the vertical field angle of the human eye-imitating optical system.
During the vertical rotation, 3 critical cases can also be used as the mark of the end of the vertical rotation, i.e. the end point of the vertical rotation.
The first critical situation is that the eye-imitating optical system sensor 7 is exactly a virtual scene, as shown in fig. 7, when the rotation angle is further increased, a non-virtual scene appears on the eye-imitating optical system sensor 7 (before that, only a virtual scene exists on the eye-imitating optical system sensor 7 because α v < θ v), and by using this feature, the rotation angle Δ v1 at this time can be recorded by observing the change of the eye-imitating optical system sensor 7, and θ v ═ α v/2 +/Δ v1 can be easily known from the geometric relationship in fig. 7.
In the case of the 2 nd critical situation, half of the virtual scene and half of the non-virtual scene appear on the human eye-imitating optical system sensor 7 again, as shown in fig. 8, the boundary between the virtual scene and the non-virtual scene is again located at the center of the vertical field of view of the human eye-imitating optical system, and by using this feature, the rotation angle Δ v2 at this time can be recorded by observing the change of the human eye-imitating optical system sensor 7, and θ v ═ Δ v2 is easily known from the geometric relationship in fig. 8.
The 3 rd critical situation is just a non-virtual scene on the human eye-imitating optical system sensor 7, as shown in fig. 9, the virtual scene is not observed on the human eye-imitating optical system sensor 7, and by using this characteristic, the rotation angle Δ v3 at this time can be recorded by observing the change of the human eye-imitating optical system sensor 7, and θ v ═ Δ v3- α v/2 is easily known from the geometrical relationship in fig. 9.
Thus, all of the above 3 rotation end points can be used to obtain the vertical field angle of the virtual scene.
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.
