使用压敏发光涂料是测量风洞模型表面压力的可行技术。该技术需要对在已知以及测试条件下获得的图像进行数据缩减以及图像的空间变换。提出了一种将图像配准到亚像素精度的通用变换，并讨论了图像配准变换的一般特征及其推导。描述了图像切除及其应用。演示了将压力数据映射到小型风洞模型的三维模型表面，其空间精度为模型长度的 0.5%。
The use of pressure sensitive luminescent paints is a viable technique for the measurement of surface pressure on wind tunnel models. This technique requires data reduction of images obtained under known as well as test conditions and spatial transformation of the images. A general transform which registers images to subpixel accuracy is presented and the general characteristics of transforms for image registration and their derivation are discussed. Image resection and its applications are described. The mapping of pressure data to the three dimensional model surface for small wind tunnel models to a spatial accuracy of 0.5 percent of the model length is demonstrated.
