Inno­v­a­tive cam­era-sup­port­ed robot control

Instal­la­tion and calibration

Accord­ing to the appli­ca­tion it is pos­si­ble to fix the cam­era direct­ly on the robot or attach it secure­ly in the sur­round­ing area. The con­troller of the cam­era and the robot are con­nect­ed via Eth­er­net and com­mu­ni­cate imme­di­ate­ly with each oth­er after imple­men­ta­tion of the instal­la­tion pro­gram of Keyence. Thus, for a more sim­ple instal­la­tion the robot can direct­ly be con­trolled by the Keyence con­troller. As soon as the cam­era is well-posi­tioned and the con­nec­tion between cam­era and robot is built the first images can be tak­en and the image pro­cess­ing can be start­ed. In order to trans­fer image ele­ments into posi­tion data a cal­i­bra­tion has to be done. For that Keyence offers an auto­mat­ic cal­i­bra­tion show­ing advan­tages com­pared to man­u­al meth­ods like being more pre­cise, repeat­able and inde­pen­dent of user and instal­la­tion loca­tion of the robot. The result of the cal­i­bra­tion is a spec­i­fi­ca­tion for a con­ver­sion of detect­ed pix­els on the cam­era image into Carte­sian coor­di­nates for the robot.
