METODE STEREO VISION DENGAN KAMERA CMOS UNTUK PENGUKURAN JARAK
ABSTRACT: Excess image sensor
digital camera is not just a picture taker or produce video, can be also as measurement tool. Through the method of image
processing, can be processed input image or an object taken from the camera.
Image processing can be thresholding, edge detection and template matching.
Required sensing with two images obtained from the stereo camera simultaneously
or stereo vision. The camera used has properties or specifications are
identical. Open CV was contribute to image processing, object interpretation
and also the calibration process. Calibration function to search for intrinsic
and extrinsic parameters of the camera. Research uses a solid object in the
form of balls of various sizes and colors. Epipolar and stereoscopic as the
method to be used, because in previous studies, it is very suitable for
processing images with color segmentation. As for digital image processing
using the method thresholding. Research results obtained, that the object of
pingpong ball motionless when lighting using sunlight has RMSE (root mean
square error) of 2.64% while the value of a tennis ball RMSE is 2.53%. Research
by lighting using indoor lighting, RMSE was 1.03% pingpong ball, tennis ball
RMSE of 2.25%. While on the moving object, either RMSE pingpong ball or a
tennis ball, its value is greater than when the motionless object. Measuring tool
using a stereo camera capable of detecting targets up to a distance of 300 cm,
but at a distance of 200 cm level of confidence does not the 95%. Lighting
greatly affect the measurement results CMOS camera, because scalar target color
easily changed.
