In order to construct high dynamic range image of high quality, a method of constructing response curve for panoramic camera is presented.This method can automatically obtain a small amount of sampling points covered the whole brightness range space of one picture, through grading the range of the brightness, the difference between the sampling point is limited meanwhile the rate of change.The constructed camera response curve shows that the camera response curve can reflect the characteristics of camera better, so the generated image shows details of both bright and dark regions well.Then this paper gets the luminance information of one scene, which has a very important significance in the light information in the virtual reality.But there are also a lot of work to do, such as devoting to improving the sharpness of the high dynamic range image and the contrast between the regions.
