Abstract:
A target for photogrammetric analytical measurement system comprising:a first bar and a second bar which are connected at adjacent end portions; indicating members that are able to be recognized in a photographed image by a camera, being placed on said first and second bars so as to define an identical plane; a box in which sensors for detecting data utilized to calculate a photographing position of said camera, being provided on said first bar or said second bar at a position close to said connecting end portions; a loop antenna that transmits said data detected by said sensors to an outer device; and a projecting portion in which said loop antenna is provided, being placed on said box at a side at which said indicating members are placed on said first and second bars, wherein, a relationship between a first distance K1 and a second distance K2 are defined by an expression to follow, said first distance K1 being along said identical plane between a first indicating member of said indicating members which is positioned close to said connecting end portions and said projecting portion, and said second distance K2 being along a direction perpendicular to said identical plane between a top surface of said projecting portion and said identical plane K2/K1
