Abstract: A system and a method for real time stereo image rectification are provided to deal with the variation of a camera medium value flexibly through hardware, and rectify images obtained in cameras in real time. A coordinate generating module(110) calculates 2 dimensional coordinates of a currently-inputted pixel based on a control signal generated in cameras receives images. A rectification coordinate generating module(120) generates rectification coordinates based on a calibration matrix inputted from the outside. A dual linear interpolation value generating module(130) generates a corresponding code after calculating a double linear interpolation value for double linear interpolation of a rectification result. A first memory(140) stores the rectification coordinates generated in the rectification coordinate generating module. A second memory(150) stores a double linear interpolation value generated in the dual linear interpolation value generating module. A third memory(160) stores an input image and an output image. A rectification module(170) performs image rectification by applying the stored rectification coordinates and the double linear interpolation value based on the output image, and outputs the rectified coordinate value. A controller(180) performs synchronization as controlling the above components.

Abstract: A real-time object tracking apparatus is provided to track a moving object using a particle filter in real time without a delay time. A real-time object tracking apparatus includes a memory, a subtracter, a filter, and a particle filter. The memory sequentially stores images of a moving object. The subtracter subtracts a previous frame from a current frame stored in the memory to obtain a subtracted image. The filter removes noise of the subtracted image. The particle filter tracks the moving object using the subtracted image from which the noise is removed. The particle filter distributes particles in the subtracted image and sets the moving direction of the moving object through the distribution density of the particles according to a probability approach in response to a variation in the particle state and a weight given to the particles.
