An unmanned aerial vehicle calibration method and system based on a color 3D calibration object. The method comprises: placing a color chequerboard 3D calibration object in a scene to be photographed; using an unmanned aerial vehicle to photograph images of the color chequerboard 3D calibration object from at least three different orientations; using a vanishing point theory to linearly solve the internal parameters of a camera of the unmanned aerial vehicle according to the photographed images of the color chequerboard 3D calibration object; and using a coordinate projection transformation method to determine a geometric constraint relationship between a spatial position and the images of the camera of the unmanned aerial vehicle according to the internal parameters of the camera of the unmanned aerial vehicle.
