Ta Distinct to 3D light-section reconstruction 3.1. Principle of Laser Triangulation Measurement6 oftechnology, the acquisiti point cloud data is equivalent for the laser triangulation measurement, wh Particular to 3D light-section reconstruction technology, the acquisition system of point nates of each and every point have to be obtained by means of the laser stripe center cloud data is equivalent to the laser triangulation measurement, exactly where the coordinates of system. The be obtained by way of of a common triangulation measurement syst every single point want tooptical structure the laser stripe centerline extraction process. The optical structure of a typical triangulationreference plane, along with the Complementary me laser is Carbendazim Purity & Documentation incident on the vertical measurement program, where the laser is incident around the vertical reference plane, as well as 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 five. Schematic diagram of your laser triangulation measurement.Figure five. Schematic diagram of the laser triangulation measurement.The original point may be the intersection on the laser along with the lens standard when the laser is incident perpendicular pointreference plane. The plane that passes by way of this point, The original towards the may be the intersection of your laser plus the lens typical which can be also perpendicular to the laser line, is taken as the reference plane. The height h of is incident perpendicular to the reference plane. The plane that passes thro the measured point on the object might be 3-Methyl-2-oxovaleric acid site expressed as:that is also perpendicular towards the laser line, is taken because the reference plan in the measured point ofhthe objectdL be expressed as: can (1) =cos(lcos + dsin)exactly where is definitely the angle among the reference plane as well as the line inside the origin point and = (the lens towards the imaging surface; the center on the lens; l may be the distance in the center of + ) d may be the distance between the imaging position and the center on the CMOS; and L may be the exactly where would be the angle among the reference plane along with the line inside the or horizontal distance among the laser as well as the CMOS. the The coordinates of every point are connected accordingcenter right topological ima center of your lens; l is the distance from the for the from the lens for the relationship to characterize the contour data of your measured object within the present may be the distance amongst the imaging position along with the center from the CMO section. Thinking of the accuracy, robustness, and versatility of the extraction process, the horizontal distance between the laser and also the CMOS. frequently applied methods for extracting the centerline of laser stripes mainly consist of the gray centroid system, the Steger approach, the Hessian matrix process, etc., which reach The coordinates of each point are connected based on the right micrometer-level sub-pixel extraction accuracy [10,11]. At present, the latest investigation within this object lationship to characterize the contour information and facts with the measured field has created particular adjustments towards the classic algorithms pointed out above for specific section. Taking into consideration however accuracy, robustness, and principle. applications, which has not thebeen a important breakthrough in versatility of your extracti Subsequently, the entire program extracting the centerline of laser stripes generally applied strategies for needs to become calibrated to map the extracted two- key dimensional pixel coordinatesthe Steger method,spaceHessian matrix.
