A system for setting an operation range of an excavation machine, comprising:

• a surroundings information acquisition unit that acquires information on an actual image of surroundings of the excavation machine;
• a user interface unit;
• and
• a controller that generates a surroundings image based on the information on the actual image acquired by the surroundings information acquisition unit and that displays, on the user interface unit, the surroundings image and a setting guidance image for setting a virtual wall that regulates the operation range of the excavation machine, wherein
• the controller receives a setting of a first position of a distal end of the excavation machine as a first point, receives a setting of a second position of the distal end of the excavation machine as a second point, and sets, as the virtual wall, a plane that includes the first point and the second point received as the setting and that is vertical to a ground.
