当一个人感到VIMS、3D晕车、晕车、晕车或头晕时，眼球经常不自觉地旋转，因此，可以从眼睛旋转运动的时间序列估计来量化这些症状。然而，在临床眼球旋转测量中，为了获得虹膜图案的灰度视频图像之间的互相关，需要将用于眼睛成像的摄像机放置在眼球的前面，这可能会在测量过程中遮挡视野。作者的研究小组设计了一种跟踪眼睛白色血管图像的方法。然而，研究不同性质的变量参数对眼球旋转运动估计的准确性、速度和稳定性的影响还不够。在这项研究中，我们选择了四个变量参数，这些参数可以用于通过模板匹配来估计眼睛旋转的图像处理，其中系统自动选择“厚的、暗的和具有特征形状的血管图像”。然后，我们对所有这些组合进行了相似性计算，并研究了哪种可变参数值会影响眼球旋转估计的准确性和稳定性。
When a person feels VIMS, 3D sickness, car sickness, space sickness, or dizziness, the eyeballs often rotate involuntarily, and therefore, quantification of these symptoms can be expected from time series estimation of eye rotation motion. In clinical eye rotation measurement, however, the camera for eye imaging is required to be placed in front of the eyeball to obtain the cross-correlation between the gray-scale video images of the iris pattern, which may obstruct the field of vision during measurement. The authors' research group devised a method to track blood vessel images in the white of the eye. However, it was insufficient to examine how variable parameters with what properties would affect the accuracy, speed, and stability of eye rotation motion estimation. In this study, we selected four variable parameters that could be used in image processing for eye rotation estimation by template matching, in which the system automatically selects blood vessel images that are "thick, dark, and of characteristic shape." We then performed similarity calculations for all of these combinations and investigated what kind of variable parameter values would affect the accuracy and stability of the eye rotation estimation.
