Surveying system, staking assistance method, and storage medium storing staking assistance program

A staking assistance method of assisting placement of a staking tool including a picket, a crossbeam, and a slope beam using a surveying system including a surveying device and a terminal device, the method comprising:

• acquiring design information including a designed slope, using a design information acquisition unit;
• surveying using the surveying device;
• transmitting, to the terminal device, surveying information on the surveying, using a surveying information acquisition unit;
• calculating an estimated altitude of a current ground in accordance with the surveying information received in the surveying information acquisition, using a current state estimation unit;
• calculating a coordinate of an intersection between the current ground and the designed slope based on the estimated altitude of the current ground and the design information including the designed slope, using an intersection calculation unit;
• determining a shape of a stake to be placed, based on the surveying information and the coordinate of the intersection, using a stake shape determination unit;
• and
• stake shape information of causing the terminal device to inform of the shape of the stake determined in the stake shape determination, using a stake shape information unit.

A storage medium storing a staking assistance program for assisting placement of a staking tool including a picket, a crossbeam, and a slope beam using a surveying system including a surveying device and a terminal device, the program configured to cause a computer to execute steps comprising:

• acquiring design information including a designed slope, using a design information acquisition unit;
• surveying using the surveying device;
• transmitting, to the terminal device, surveying information on the surveying, using a surveying information acquisition unit;
• calculating an estimated altitude of a current ground in accordance with the surveying information received in the surveying information acquisition, using a current state estimation unit;
• calculating a coordinate of an intersection between the current ground and the designed slope based on the estimated altitude of the current ground and the design information including the designed slope, using an intersection calculation unit;
• determining a shape of a stake to be placed, based on the surveying information and the coordinate of the intersection, using a stake shape determination unit;
• and
• causing the terminal device to inform of the shape of the stake determined in the stake shape determination, using a stake shape information unit.
