Process planning strategies for surface hardening by laser robot was introduced. It has many characteristics, such as integration, flexibility and environmental protection. According to technology requirement, the path planning and robotic hardening program were accomplished automatically. The FANUC ROBOGUIDE was used to realize simulation. Experiments were carried out to evaluate the application of process planning strategies for laser surface hardening.

“…Camera imaging model is the mathematical description of physical processes that the object image to the image plane, divided into linear and nonlinear models [3]. Under the premise of ignoring all the optical lens distortion, the camera model that objects project onto the imaging plane through the center of the camera optical axis is the linear model-the pinhole model [4]. In the pinhole model, we can get the relationship between any point P(Xw Yw Zw) in the world coordinate system and its projective point p(Xc Yc Zc), which can be calculated by the Eq.1:…”

As an advanced repair technology, the laser remanufacturing technology has been paid much more attentions recently. The authors previously studied the vision calibration by using the Matlab Calibration toolbox. Since the boundaries of a single image have to be specified manually, however, the Matlab toolbox based calibration method will be time consuming and low precision. This article continues the study of vision calibration for laser remanufacturing machine system and proposes a new binocular vision calibration method based on Halcon10.0 software. Experimental results show that the proposed calibration process consumes shorter time and is able to achieve higher precision.

This paper introduces a solution for laser scanning system, which utilizes machine vision technology. It includes algorithm for positioning and matrix for scanning control. The system can be used to detect an object and laser mark on specific position. This work explains how to use one CCD to catch an object’s position variation relative to a reference point, and how to translate the different coordination systems for laser scanner etc.
