Abstract

This paper proposes a method to improve the accuracy of 3D measurement of a stereo camera by marking a measured object using a line laser. Stereo cameras are commonly used for 3D measurement, but the accuracy of 3D measurement is affected by the amount of texture. Therefore, a new measurement system combining a stereo camera and a line laser is developed. The accuracy of 3D measurement with a stereo camera is improved by using a line laser to mark arbitrary points on the measured object and measuring the marked points, regardless of the amount of texture on the measured object. Because the laser is only used to mark points on the measurement target, calibration is not required with the stereo camera. Experimental evaluation showed that our proposed method can obtain millimeters.

立体相机与线激光高精度三维测量的实验评价

提出了一种利用直线激光对被测物体进行标记，提高立体相机三维测量精度的方法。立体相机通常用于三维测量，但三维测量的精度受纹理量的影响。为此，研制了一种立体相机与直线激光器相结合的新型测量系统。采用直线激光在被测物体上标记任意点并测量被标记点，而不考虑被测物体上纹理的多少，从而提高了立体相机三维测量的精度。由于激光仅用于标记测量目标上的点，因此不需要使用立体摄像机进行校准。实验结果表明，该方法可以获得毫米级的精度。
