Ta Specific to 3D light-section reconstruction 3.1. Principle of Laser Triangulation Measurement6 oftechnology, the acquisiti point cloud data is equivalent to the laser triangulation measurement, wh Distinct to 3D light-section reconstruction technologies, the acquisition process of point nates of every single point need to be obtained by means of the laser stripe center cloud information is equivalent for the laser triangulation measurement, where the coordinates of strategy. The be obtained by means of of a standard triangulation measurement syst every single point have to have tooptical structure the laser stripe centerline extraction process. The optical structure of a typical triangulationreference plane, along with the Complementary me laser is incident on the vertical measurement system, exactly where the laser is incident around the vertical reference plane, and also the Complementary metal oxide semiconductor (CMOS) iconductor (CMOS) is placed obliquely, is shown in Figure five. is placed obliquely, is shown in Figure five.Figure 5. Schematic diagram in the laser triangulation measurement.Figure five. Schematic diagram of the laser triangulation measurement.The original point could be the intersection on the laser and the lens regular when the laser is incident perpendicular pointreference plane. The plane that passes via this point, The original for the would be the intersection of your laser along with the lens standard which is also perpendicular for the laser line, is taken because the reference plane. The height h of is incident perpendicular for the reference plane. The plane that passes thro the measured point from the object can be expressed as:that is also perpendicular to the laser line, is taken as the reference strategy from the measured point ofhthe objectdL be expressed as: can (1) =cos(lcos + dsin)where could be the angle between the reference plane as well as the line within the origin point and = (the lens towards the imaging surface; the center of your lens; l could be the distance from the center of + ) d may be the distance between the imaging position as well as the center on the CMOS; and L could be the where is the angle in between the reference plane and also the line within the or horizontal distance in between the laser along with the CMOS. the The coordinates of every single point are connected accordingcenter correct topological ima center on the lens; l is definitely the distance in the to the from the lens to the relationship to characterize the contour data of your measured object inside the present is the distance between the imaging position as well as the center of the CMO section. Contemplating the accuracy, robustness, and versatility in the extraction method, the horizontal distance between the laser and also the CMOS. normally applied strategies for extracting the centerline of laser U0126 Purity stripes primarily include things like the gray centroid technique, the Steger system, the Hessian matrix technique, and so forth., which achieve The coordinates of each and every point are connected according to the correct micrometer-level sub-pixel extraction accuracy [10,11]. At present, the Risperidone-d4 web latest analysis in this object lationship to characterize the contour data in the measured field has produced particular adjustments towards the classic algorithms described above for particular section. Thinking about however accuracy, robustness, and principle. applications, which has not thebeen a considerable breakthrough in versatility with the extracti Subsequently, the whole system extracting the centerline of laser stripes normally applied strategies for wants to become calibrated to map the extracted two- main dimensional pixel coordinatesthe Steger system,spaceHessian matrix.
