The invention relates to the leveling field of a theodolite, in particular to a three-supporting-point theodolite leveling device and a leveling method. The device is characterized in that a first supporting leg, a second supporting leg and a third supporting leg are arranged in a regular triangle manner; three supporting points are uniformly distributed on three points on the circumference of the theodolite; an angle detector is arranged on a theodolite platform, and is arranged at a midpoint of a side of the regular triangle formed by a first fine-adjusting motor, a second fine-adjusting motor and a third fine-adjusting motor. The device and the method disclosed by the invention have the advantages that the adjustment speed is quick, and two shafts are relatively independent during an adjustment process, therefore the leveling algorithm is simplified. 本发明涉及经纬仪的调平领域，特涉及种三个支点调平经纬仪的装置及调平方法。本发明的撑腿、撑腿二、撑腿三为正三角形设置，三个支撑点均匀的分布在经纬仪圆周的三个点上，角度检测器安装在经纬仪平台上，且角度检测器安装在精调电机、精调电机二、精调电机三所形成正三角形的条边的中点上。本发明具有调节速度快，调节过程中两个轴相对独立
