An omnidirectional image measuring instrument comprises a horizontal rotary table, a horizontal rotary driving unit capable of rotating the horizontal rotary table at a constant speed, an EDM device and an image pickup device provided on the horizontal rotary table, and a control device for synchronously controlling a distance measurement by the EDM device and an image pickup by the image pickup device. The control device rotates the horizontal rotary table at every predetermined angle, operates the image pickup device, acquires single images at every predetermined rotational angle over a total circumference, combines the single images, prepares an omnidirectional image, performs scanning with a distance measuring light from the EDM device, carries out the distance measurement at every predetermined rotational angle over the total circumference, calculates a horizontal angle and a vertical angle of a distance measuring point from the omnidirectional image and obtains three-dimensional data of the measuring point.
