但Braintech Inc.认为它有更好的主意。Babak Habibi是北温哥华的总裁加拿大加拿大公司的公司表示，Braintech的SC3D Vision技术可以使用一台摄像机使用单个图像进行3D零件位置。
SC3D—which stands for Single Camera 3 Dimensional—works by focusing on key features, or “landmarks” on a target part, and applying a method called “perspective distortion,” says Habibi. And under terms of a partnership with robotics vendor ABB Inc, SC3D technology has been applied for what Habibi calls “semi-structured” or “semi-constrained” robotic bin-picking applications at numerous North American automotive factories.
According to Jerry Osborn, vice president and general manager of ABB’s Robot Automation Division, in Auburn Hills, Mich., around 60 out of 100 Braintech vision-guided ABB robot applications in the field qualify as “semi-structured bin-picking.” The customer list includes DaimlerChrysler, Delphi, Ford, General Motors, Honda, Nissan and Toyota.
在这些应用中，由于SC3D机器人指导，零件可以在机器人拣选中松散地限制，往往消除了昂贵的精确邓氏的需求。在主要的汽车课程中，节省的量可以达到“数十万美元，只为一组垫料为一组零件，”他争辩。另一个主要的储蓄来通过劳动力减少，奥斯本增加，“因为我们已经闯入手动完成的应用程序，以前不可行。”
一个最终用户对该技术感到满意的是丰田汽车制造业（TMMWV）工程师助理经理Bob Welch，这是一家在布法罗，W夫人的动力列车厂。丰田植物安装了五个SC3D引导的ABB机器人去年作为汽缸块和头部的原料卸载系统。韦尔奇表示，该系统通过降低一些加工区域的劳动力成本，帮助提高了TMMWV的生产率。
“The beauty of the ABB/Braintech solution is that it’s 3D vision with one camera,” Welch observes, “so the complexity to the user is minimal, and you don’t have a two-camera system that you’re trying to keep calibrated.”
