3D SCAB Position Correction Vision System
· Calculate the amount of movement (Δx, Δy, Δz, ΔRx, ΔRy, ΔRz) compared to the reference vehicle by applying a matching algorithm
· Transmit the calculated amount of movement to the industrial robot, apply it as an offset, and mount it
· Apply technology to scan at least three vehicle frames and merge them into a single pointer cloud
· The error rate is low and the movement calculation is significantly better even if the position of the vehicle to be installed is tilted or rotated.
· When measuring 3D SCAN, position correction rate is better than 2D vision
Application of 3D scan Position Correction Vision System
· AITZ 3D Glass Mounting System: 3D Area Scan Sensor measures the body frame on which the glass will be mounted to extract point cloud data
· AITZ 3D Tire Fastening System: 3D Area Scan Sensor measures the wheel hub where the tire will be mounted to extract point cloud data
