Abstract

Determining site settings for robotic laser inspection systems typically requires an interactive two-step teaching process. The first-step of the process sets inspection locations of a laser device over an inspection site through a command from a vision computer. In command mode the vision computer stores coordinates of the head positions, while composing and sending to the laser device a string containing a command, a laser head number and parameter settings. During the second step results of the laser measurement are sent from the laser device to the vision computer to be displayed and/or stored for later use. Included in the second step of the process is verification by an operator, which requires that the vision computer be changed from command mode to a graphical mode, in which screens are available for viewing the laser measurements. Subsequent to operator inspection, based on current laser position and selected parameters refinements to the laser device would need to be made, since the laser device is made up of a number of point lasers aligned end to end to form a laser line. This iterative refining process entails repeating the two-step inspection site setting process until the laser device is positioned correctly.

Determining site settings for robotic laser inspection systems typically requires an interactive two-step teaching process. The first-step of the process sets inspection locations of a laser device over an inspection site through a command from a vision computer. In command mode the vision computer stores coordinates of the head positions, while composing and sending to the laser device a string containing a command, a laser head number and parameter settings. During the second step results of the laser measurement are sent from the laser device to the vision computer to be displayed and/or stored for later use.

This iterative refining process entails repeating the two-step inspection site setting process until the laser device is positioned correctly.

Proposed is an improved method of teaching robotic inspection site locations for laser inspections systems by enabling dynamic interactive control between the laser device and the vision computer. The improvement comprises modifying the iterative two-step teaching process described above by intercepting data sent between the vision computer and the laser device using a personal computer (PC) or the like, in order to allow interactive adjustments to laser device settings before they are sent to the vision computer and assembled for graphical display.

More specifically, an asynchronous communication protocol between the vision c...
