Velocity Estimation In Remotely Sensed Imagery

A computer-implemented method for estimating velocity of a moving object, comprising:

• receiving, by an image processing system, an image, which includes a first strip generated by a first sensor and a second strip generated by a second sensor;
• recognizing, by the image processing system, a moving object in the first strip of the image;
• selecting, by the image processing system, a plurality of stationary objects that are captured with the moving object in the first strip of the image, while excluding stationary object(s) in the second strip of the image, wherein the plurality of stationary objects are non-moving features;
• combining, by the image processing system, misregistration values for the plurality of stationary objects in the first strip of the image;
• and
• calculating, by the image processing system, a velocity of the moving object, based on a raw velocity of the moving object and the combined misregistration values.

A non-transitory processor readable storage device having processor readable code embodied on the non-transitory processor readable storage device, wherein the processor readable code, when executed, causes one or more processors to:

• receive an image, which includes a first strip generated by a first sensor and a second strip generated by a second sensor;
• recognize a moving object in the image;
• and
• when the moving object is in the first strip of the image:
• select a first plurality of stationary objects that are captured with the moving object only in the first strip of the image, wherein the first plurality of stationary objects are non-moving features;
• combine first misregistration values for the first plurality of stationary objects;
• and
• calculate a velocity of the moving object, based on a raw velocity of the moving object and the combined first misregistration values;
• and
• when the moving object is in the second strip of the image:
• select a second plurality of stationary objects that are captured with the moving object only in the second strip of the image, wherein the second plurality of stationary objects are non-moving features;
• combine second misregistration values for the second plurality of stationary objects;
• and
• calculate a velocity of the moving object, based on a raw velocity of the moving object and the combined second misregistration values.
