The embodiment of the invention discloses a remote sensing satellite multi-target on-satellite autonomous task planning method and a remote sensing satellite multi-target on-satellite autonomous task planning system. In one specific embodiment, the method comprises the following steps: processing orbit determination data in a current period to generate an orbit forecast and performing coordinate conversion; screening the longitudes of the ground targets to obtain alternative imaging targets, and sorting the alternative imaging targets according to the ground shadow constraint, the ascending orbit and the descending orbit to obtain an imaging target set; performing imaging time and side swing angle calculation on the imaging target set to obtain an imaging time sequence and an imaging resource demand, and generating an imaging path matrix; and obtaining an imaging task plan according to the imaging path matrix, the power consumption and the importance weight. According to the implementation mode, the on-satellite solid storage capacity and the energy constraint are comprehensively considered according to the importance of the ground target, the time complexity and the space complexity of the multi-target task planning method are effectively reduced, and on-satellite implementation is facilitated.
