Three-dimensional Positioning Guidance of Automobile Doors Based on Machine Vision
At present,in workshops,parts fixed on fixtures were commonly guided and gripped by pre-teaching the motion trajectories of robotic arms,resulting in poor human-machine interaction and low levels of intelligence.Machine vision,as an effective means of non-contact sensing and meas-urement,was applied in industrial scenarios.Based on monocular vision pose measurement technolo-gy,a multi-camera PnP positioning model and robotic arm guiding model were established to achieve spatial perception and guided grasping of the parts.Additionally,a pre-calibration method was pro-posed using multi-zero anchors to compensate system errors between robotic arm and vision module,which effectively decreasing the positioning and guiding errors of large parts.
