Increasing demands for accurate reconstruction of the non-cooperative target are arising recent years.The existing methods which combine cameras and laser range finders(LRF)are inconvenient and costly.A new vision system is proposed that the widely used laser range finder is replaced with a simple laser.The combination of a camera and a simple calibrated laser is also highly accurately enough to reconstruct the three-dimensional position of the laser spot,while the cost much less than LRF.Also,a method to c...
