A survey data processing device comprising: a positioning data receiving unit configured to receive positioning data, the positioning data being obtained through tracking and positioning a reflective prism of an aerial vehicle by a total station, the aerial vehicle mounted with the reflective prism and a camera in which positional relationship and attitude relationship therebetween are known; a relative orientation unit configured to calculate relative exterior orientation parameters of the camera by relative orientation of photographed images taken by the camera; an absolute orientation unit configured to obtain absolute values for the relative exterior orientation parameters of the camera by absolute orientation on a basis of the positioning data and the relative exterior orientation parameters; an adjustment calculation executing unit configured to correct the absolute values for the relative exterior orientation parameters on a basis of a position relationship between the camera and the reflective prism, which is preliminarily obtained; and a positioning data correcting unit configured to correct the positioning data of the reflective prism, characterized in that displacement of a reflection point of the reflective prism from a planned position occurs depending on an incident angle of each of measurement light and tracking light from the total station, a relationship between the incident angle of each of the measurement light and the tracking light from the total station to the reflective prism and the displacement of the reflection point of each of the measurement light and the tracking light on the reflective prism is preliminarily obtained, and the positioning data correcting unit is configured to correct the positioning data on a basis of attitude in an absolute coordinate system of the reflection prism, which is obtained from the corrected absolute values for the relative exterior orientation parameters, an orientation direction of the the total station, and the preliminarily obtained relationship between the incident angle to the reflective prism and the displacement of the reflection point. a positioning data receiving unit configured to receive positioning data, the positioning data being obtained through tracking and positioning a reflective prism of an aerial vehicle by a total station, the aerial vehicle mounted with the reflective prism and a camera in which positional relationship and attitude relationship therebetween are known; a relative orientation unit configured to calculate relative exterior orientation parameters of the camera by relative orientation of photographed images taken by the camera; an absolute orientation unit configured to obtain absolute values for the relative exterior orientation parameters of the camera by absolute orientation on a basis of the positioning data and the relative exterior orientation parameters; an adjustment calculation executing unit configured to correct the absolute values for the relative exterior orientation parameters on a basis of a position relationship between the camera and the reflective prism, which is preliminarily obtained; and a positioning data correcting unit configured to correct the positioning data of the reflective prism, characterized in that displacement of a reflection point of the reflective prism from a planned position occurs depending on an incident angle of each of measurement light and tracking light from the total station, a relationship between the incident angle of each of the measurement light and the tracking light from the total station to the reflective prism and the displacement of the reflection point of each of the measurement light and the tracking light on the reflective prism is preliminarily obtained, and the positioning data correcting unit is configured to correct the positioning data on a basis of attitude in an absolute coordinate system of the reflection prism, which is obtained from the corrected absolute values for the relative exterior orientation parameters, an orientation direction of the the total station, and the preliminarily obtained relationship between the incident angle to the reflective prism and the displacement of the reflection point.
