To provide a target support capable of positioning a target pole at a survey point and supporting the target pole in a state along the vertical direction with a simple configuration.SOLUTION: The target support 1 supports a target pole 100 to be detected by a surveying device. A target support tool 1 includes a support tool body 2 installed on an installation surface, a pole support member 30 that is attached to the support tool body, has a support hole 32 through which a target pole 100 penetrates, and supports the target pole by the support hole, and a connection member 40 that connects the pole support member to the support tool body so as to be relatively movable in a direction along an installation surface G and holds the pole support member at a predetermined position. The target support tool 1 positions the target pole 100 at a survey point, and supports the target pole in a state along the vertical direction by relatively moving the pole support member 30.SELECTED DRAWING: Figure 5

The utility model relates to the technical field of geographical surveying and mapping, in particular to a portable geographical surveying and mapping positioning support which comprises a mounting support, shaft seats are arranged on the four sides of the side face of the mounting support, torsion rotating shafts are arranged at the bottom ends of the shaft seats, and the bottom ends of the shaft seats are movably connected with rotating supporting legs through the torsion rotating shafts. Moving wheels are arranged at the bottom ends of the rotating supporting legs, the surface of the mounting support is sleeved with a storage cover, and a mounting frame is fixedly connected to the top end of the storage cover. Through the arrangement of the mounting bracket, the shaft seat, the torsion rotating shaft, the rotating supporting leg, the moving wheel, the buffer spring seat, the first butt-joint plate, the supporting base and the second butt-joint plate, the device can carry out more portable geographical surveying and mapping positioning bracket moving use operation; a worker firstly moves and uses the whole equipment by lifting the mounting bracket, and after the equipment is moved to a specified position, the bottom end of the mounting bracket can be lowered to the ground.

To provide a three-dimensional measurement method of a member capable of achieving highly accurate measurement in a short time, from a ground surface easily, without climbing up to a measurement object member, in measurement of a high building structure.SOLUTION: A three-dimensional measurement method comprises: a first step of selecting, as reference points, multiple points having a height coordinate value different from that of a measurement object member from a range of a structure or the like; a second step of acquiring photograph image data about the measurement object member and a range including the respective reference points by using a photograph image data measurement instrument; a third step of acquiring a reference point coordinate value which is made into a three-dimensional coordinate value by using a three-dimensional measurement instrument; a fourth step of acquiring imaging point group data from the photograph image data; a fifth step of performing calibration applying the reference point coordinate value with respect to a calibration three-dimensional coordinate value in the imaging point group data and acquiring a calibrated imaging point group data; and a sixth step of calculating a distance between the measurement object points, on the basis of the calibrated imaging point group data.SELECTED DRAWING: Figure 1
