| We are investigating mines in the vicinity of Joplin, Mo. using drill holes as the mines are about180'deep and flooded. We are going to use a down hole video camera but due to time constraints we can not locate the holes closer than 200 to 300' apart. In the past we have used a still 35mm camera and stereo pairs to estimate distances. Does anyone know if it is possible to estimate distances from a video. |
