Abstract: A novel method of object pose estimation based on three dimensional registration for assembly robot is presented. The spatial registration parameters can be computed by finding which projection of the volume is the most similar to the camera image. We compute the Fourier Transform (FT) of the volume projection by using FT projection theorem. A cost function is designed according to the magnitude of projection FT and image FT. Registration parameters is obtained by using Complicated System Genetic Algorithm (CSGA) to minimise the cost function. Assembly experiment made on our robot system shows our method is efficient and practical.
