1. An image processing apparatus, comprising:
circuitry configured to:
control a flight of the image processing apparatus based on a predetermined route planning including a flight route of the imaging processing apparatus and a control point at which a survey marker is positioned;
capture at least one image based on the flight route and the control point;
detect the survey marker contained in the at least one image; and
output information about the detected survey marker,
wherein the detection is performed based on a range of hue of the survey marker which is obtained under an illuminance condition indicated by a distribution of illuminance of the survey marker, the range of hue being estimated by using the distribution of illuminance of the survey marker,
wherein the output information includes the image of the survey marker and a position of the survey marker in the captured image,
wherein the survey marker includes a plurality of circles concentrically disposed and each having a different radius, and
wherein the survey marker includes a built-in illuminance detection apparatus that detects illuminance, in a portion of a circle having a smallest radius among the plurality of circles.
