The embodiment of the invention discloses a method and a device for automatically correcting the captured picture in a virtual three-dimensional space. According to the method, the preset house is adjusted by constructing the target coordinate system of the virtual three-dimensional space diagram of the preset house so that the plane of the floor of the preset house is perpendicular to the screen.While keeping the plane of the floor perpendicular to the screen, the contents of the captured picture are displayed on the screen by adjusting the position of the points and the angle of view and then picture capturing is performed. According to the method, the preset house is adjusted to the upright state according to the target coordinate system, picture capturing is performed under the condition that the preset house is in the upright state and the captured picture is not tilted so that the display effect of the pictures in the use process can be guaranteed. Besides, the preset house is automatically adjusted to the upright state according to the target coordinate system so as to avoid tediousness and error of manual adjustment.
