Design of a Convenient Trapezoidal Geometry Correction System for Household Projectors
摘要
Abstract
A convenient trapezoidal geometric correction system based on DToF ranging sensor module,three-axis acceleration sensor module,and image transformation is designed to address the problem of trapezoidal distortion imaging caused by household projectors as it has not facing imaging plane.This system can achieve automatic correction of trapezoidal distortion screen without manual intervention.At the same time,a maximum inscribed rectangle algorithm based on vertex pre calibration is introduced to assist in achieving maximum area and non distortion aspect ratio in distortion correction screen.The experimental results show that the system can correct the trapezoidal distortion imaging of the projector in complex spatial poses with low hardware cost and convenient operation,enhancing the viewing comfort.关键词
