Rding for the experiment result, the accuracy ofof horizontal displacement meaAccording towards the experiment result, the accuracy horizontal displacement measurement is is far better than , relative for the conversion coefficient of 0.0359, theButalbital-d5 custom synthesis center surement improved than m, relative for the conversion coefficient of 0.0359, the center positioning accuracy is much better than 0.2 pixels. positioning accuracy is much better than 0.2 pixels. 4.two. Principle Verification Experiment around the attitude Positioning Accuracy of Cross Laser-Pattern Laser-Pat4.two. Principle Verification Experiment around the Attitude Positioning Accuracy of tern The attitude of cross laser refers to the angles of or Y axis of cross laser line inside the The attitude of cross laser refers to the angles of XX or Y axis of crosslaser line in the image coordinates. Since the theoretical angle value of X or Y laser line in image coimage coordinates. Because the theoretical angle value of X or Y axisaxis laser line in image coordinates can not obtained directly, the attitude positioning accuracy was indirectly ordinates cannot be be obtained directly, the attitude positioning accuracy wasindirectly verified by rolling angle measurement experiment. verified by aarolling angle measurement experiment. The experimental schematic diagram and experimental method is shown in FigThe experimental schematic diagram and also the the experimental process is shown in Figure 17: ure 17:(a)(b)Figure 17. (a)Schematic diagram in the experiment. (b)Process picture ofof the experiment. Figure 17. (a) Schematic diagram from the experiment. (b) Procedure image the experiment.Prior to the experiment, the cross laser is fixed to a higher precision turntable with adapting aspect, the accuracy from the turntable is “, and to make sure the laser projection axis was Cyclohexanecarboxylic acid Purity coaxial with the turntable axis, the laser position is adjusted. That may be, the center of cross laser image does not modify in the image coordinate when rotating the turntable.Appl. Sci. 2021, 11,(a)(b)14 ofFigure 17. (a)Schematic diagram from the experiment. (b)Procedure picture in the experiment.Ahead of the experiment, the cross laser is fixed to a high precision turntable with Just before the experiment, the cross laser is fixed to a higher precision turntable with adapting portion, the accuracy of the turntable is “, and to ensure the laser projection axis adapting component, the accuracy with the turntable is “, and to make sure the laser projection axis was coaxial together with the turntable axis, the laser position is adjusted. That is, the center of was coaxial with the turntable axis, the laser position is adjusted. That is certainly, the center of cross laser image will not alter the image coordinate when rotating the the turntable. cross laser image will not change inin the image coordinate when rotating turntable. The measurement principle is shown in Figure 18. The measurement principle is shown in Figure 18.Figure 18. Schematic diagram of your experiment principle. Figure 18. Schematic diagram with the experiment principle.As a way to express conveniently, the cross laser only draws the X axis laser line. Right here, 0 is In an effort to express line at the initial moment in onlyimage coordinate program and 1 angle from the laser conveniently, the cross laser the draws the X axis laser line. Here, 0 is angle from the laser line in the initial moment in the image coordinate system and 1 may be the angle of laser line within the image coordinate program right after rotation. m represents is definitely the angle of laser line in the image coordinate s.
