The invention discloses a line patrol robot based on a four-rotor aircraft. The line patrol robot comprises a power supply module, a switching power supply, a linear voltage stabilizer, a TI single-chip microcomputer, a six-axis attitude module, an optical flow fixed-point module, a laser fixed-height module, a vision module, an electronic speed regulator and a brushless motor. Laser ranging and optical flow positioning are adopted, the laser monochromaticity is good, the directivity is high, a laser device serves as a light source for ranging, the weight and power consumption can be remarkably reduced, and the ranging precision is improved; and high-precision positioning of the aircraft can be achieved indoors by means of optical flow velocity measurement and integral positioning, the whole system can inspect the states of a power line and a tower, shooting and storage are conducted when abnormality is found, and tasks are transmitted to a ground device to be displayed after being finished.
