测量距离和角度与喉动态镜图像关系的实验研究

Study on the Correlation of Distance and Angle with the Image of Laryngostroboscope

探讨喉动态镜成像大小与被检测对象间距离及角度的关系及其密切程度。使用基于虚拟仪器的喉动态观测系统,测量大小固定的物体,取不同距离、不同角度时所呈现图像的面积与长度。结果:当被测物体大小固定时,测量距离对被测物体所呈现的喉镜图像的面积和长度有显著影响,而测量角度对被测物体所呈现的喉镜图像的面积和长度无显著影响。

To research the correlation of distance and angle with the image of laryngostreboscope and the degree of their correlation. Methods： This research measured the area and length of the image of a same size object from different distance and angle was measured by the larynx dynamic observing system based on the virtual instruments. The results showed that when the size of object was fixed, the area and length of the image of the laryngostroboscope is obviously related with measure distance, and it is not related with metrical angle.
