In-orbit real-time detection and recognition method for transient point source target of remote sensing satellite

The invention discloses an in-orbit real-time detection and recognition method for a transient point source target of a remote sensing satellite. The method comprises the following steps: determininga background evaluation value of a pixel and a transient change value of the pixel; judging whether the pixel has a suspected point source target or not according to the adaptive threshold and the transient change value of the pixel; If the suspected point source target exists, recording, downloading and locking the background evaluation value, If the suspected point source target does not exist,updating the background evaluation value of the next frame. According to the invention, on-orbit real-time detection and recognition of a transient point source target by a remote sensing satellite can be realized. Compared with the prior art, the method has the advantages that the hardware size and power consumption can be reduced, the detection rate is not lower than 95%, a flexible on-orbit instruction adjustment mechan
