Two-dimensional coordinate image measurement system based on angle intersection

Aiming at the problem of detection and positioning of reference plane obstacles, an embedded image detection system using angle intersection method to measure two-dimensional coordinates was designed. The two-line method was adopted to calibrate the linear array CCD image sensor by two-dimensional coordinate measurement system, and the angle intersection method was used to calculate the coordinates of the measured object, so that the uncorrected two-dimensional coordinate measurement results were obtained. The control variable method was used to measure the coordinates of X axis and Y axis, respectively, the Matlab software was used to process the data, and the polynomial linear fitting of the measurement errors of X axis and Y axis was carried out respectively to obtain the coordinate correction formula, in which the corrected two-dimensional coordinate errors became significantly smaller. The experimental results show that the two-dimensional coordinate image measurement system based on angle intersection can measure two-dimensional coordinates in real time, accurately, quickly and reliably, and provides a feasible scheme for two-dimensional coordinate measurement of reference plane obstacles, which has certain application values and significance.
