Ta Particular to 3D light-section reconstruction 3.1. Principle of Laser Triangulation Measurement6 oftechnology, the acquisiti point cloud information is C2 Ceramide manufacturer equivalent for the laser triangulation measurement, wh Specific to 3D light-section reconstruction technologies, the acquisition system of point nates of each point have to be obtained by way of the laser stripe center cloud information is equivalent for the laser triangulation measurement, where the coordinates of process. The be obtained via of a common triangulation measurement syst every single point need to have tooptical structure the laser stripe centerline extraction process. The optical structure of a common triangulationreference plane, along with the Complementary me laser is incident on the vertical measurement technique, exactly where the laser is incident around the vertical reference plane, and the Complementary metal oxide semiconductor (CMOS) iconductor (CMOS) is placed Ikarugamycin supplier obliquely, is shown in Figure 5. is placed obliquely, is shown in Figure 5.Figure five. Schematic diagram in the laser triangulation measurement.Figure five. Schematic diagram in the laser triangulation measurement.The original point would be the intersection with the laser plus the lens regular when the laser is incident perpendicular pointreference plane. The plane that passes via this point, The original towards the could be the intersection with the laser and also the lens typical which can be also perpendicular to the laser line, is taken because the reference plane. The height h of is incident perpendicular towards the reference plane. The plane that passes thro the measured point in the object is usually expressed as:which is also perpendicular to the laser line, is taken as the reference plan of your measured point ofhthe objectdL be expressed as: can (1) =cos(lcos + dsin)exactly where is definitely the angle among the reference plane along with the line inside the origin point and = (the lens to the imaging surface; the center of the lens; l will be the distance from the center of + ) d would be the distance involving the imaging position along with the center in the CMOS; and L is the where may be the angle between the reference plane and the line within the or horizontal distance among the laser plus the CMOS. the The coordinates of each point are connected accordingcenter appropriate topological ima center with the lens; l will be the distance in the towards the from the lens for the relationship to characterize the contour information and facts of your measured object within the existing will be the distance between the imaging position as well as the center in the CMO section. Thinking of the accuracy, robustness, and versatility from the extraction approach, the horizontal distance among the laser as well as the CMOS. normally used techniques for extracting the centerline of laser stripes mostly contain the gray centroid system, the Steger method, the Hessian matrix method, and so on., which obtain The coordinates of every point are connected in line with the appropriate micrometer-level sub-pixel extraction accuracy [10,11]. At present, the newest analysis in this object lationship to characterize the contour details in the measured field has produced particular adjustments to the classic algorithms mentioned above for specific section. Thinking of yet accuracy, robustness, and principle. applications, which has not thebeen a significant breakthrough in versatility in the extracti Subsequently, the whole program extracting the centerline of laser stripes typically made use of methods for requires to become calibrated to map the extracted two- principal dimensional pixel coordinatesthe Steger approach,spaceHessian matrix.
