摘　　要：地面数字全景相机能够直接在水平方向上形成连续影像，这一特性决定了其具有高效三维目标重构潜力，因此建立适用的传感器模型以挖掘地面数字全景相机的潜在量测精度显得很有必要。本文使用了一种新研的地面数字全景相机进行有关试验，设计了与传统小孔成像模型有着根本区别的特有数学模型，并对所设计传感器模型进行精度评估；同时，给出了相机的三维点定位精度测试结果。The terrestrial digital panoramic cameras can get a continuous image in the horizontal direction directly, which determines that they have an efficient three -dimensional object reconstruction potential. So it is necessary to develop an appropriate sensor model to tap the potential of terrestrial digital panoramic camera measurent accuracy. The test was conducted using a new study digital terrestrial panoramic camera in this paper. A specific sensor model is designed which is different from the small hole imaging traditional model. The accuracy assessment of the designed sensor model is carried out and the accuracy test results of 3 D point positioning are worked out in the paper.
