The present invention discloses a biology power plant stack point cloud data collection and volume calculation method. The method comprises the steps of: employing a mode of simultaneous detection ofa GPS position indicator and a three-dimensional laser scanner to perform rough processing of the three-dimensional point cloud data; performing fine processing of the three-dimensional point cloud data after rough processing; and calculating the volume of the stack based on the three-dimensional point cloud data after fine processing. For key technologies of system error correction and point cloud registering in the field, the biology power plant stack point cloud data collection and volume calculation method is combined with biology power plant stack features, employs the mode of simultaneous detection of the GPS position indicator and the three-dimensional laser scanner to improve the efficiency of the point cloud collection, performs noise processing through setting of a threshold value based on stack curve fi
