The invention discloses a program-control image collection method for a multi-rotor aircraft, relates to the technical field of unmanned aerial vehicles, and can be used to solve the problem that tour inspection cannot be completed unless a worker approaches a work site and implements manual control. The method comprises that an image collection equipment is mounted on the multi-rotor aircraft, collects image information in a specific path, and sends the image information to a ground station via a wireless network; a program-control flight module in the ground station sets a route point according to an output result of an environment construction module in the ground station; information of the route point is sent to the multi-rotor aircraft via the wireless network; and a flight control module in the multi-rotor aircraft tracks the route point output by the ground station. A motion capturing device obtains accurate environment information, route point information, real-time position and attitude information of the aircraft and position information of collection images. The method is suitable for occasions in which satellite signals are weak.
