Frame rate up-conversion motion estimation method and frame rate up-conversion motion estimation system based on Kalman filtering

The invention discloses a frame rate up-conversion motion estimation method and a frame rate up-conversion motion estimation system based on Kalman filtering. The method comprises the following steps: first, the parameters and the initial value of state of a Kalman filtering model are set to make the model accord with the actual system; then, the observed value of a motion vector is obtained through a strategy in which unidirectional motion estimation is carried out first and then a unidirectional motion vector is mapped to an interpolated frame; and finally, an observation vector is updated by a time-variant gain Kalman filtering method so as to obtain a more accurate motion vector. Based on the method, a frame rate up-conversion motion estimation hardware architecture based on Kalman filtering is put forward. High utilization rate and high throughput of the system are realized through an alternate block scanning sequence and two parallel data channels.
