Ta Specific 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 Precise to 3D light-section reconstruction technology, the acquisition approach of point nates of each point ought to be obtained by way of the laser stripe center cloud information is equivalent for the laser triangulation measurement, where the coordinates of technique. The be obtained through of a common triangulation measurement syst each and every point need to have tooptical structure the laser stripe centerline extraction strategy. The optical structure of a common triangulationreference plane, and also the Complementary me laser is incident on the vertical measurement method, exactly where the laser is incident on the vertical reference plane, and the Complementary metal oxide semiconductor (CMOS) iconductor (CMOS) is placed obliquely, is shown in Figure 5. is placed obliquely, is shown in Figure five.Figure five. Schematic diagram in the laser triangulation measurement.Figure five. Schematic diagram in the laser triangulation measurement.The original point is the intersection with the laser along with the lens regular when the laser is incident perpendicular pointreference plane. The plane that U0126 Autophagy passes by way of this point, The original towards the may be the intersection with the laser plus the lens typical that is also perpendicular towards the laser line, is taken as the reference plane. The height h of is incident perpendicular towards the reference plane. The plane that passes thro the measured point of the object may be expressed as:that is also perpendicular to 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 would be the angle among the reference plane as well as the line inside the origin point and = (the lens for the imaging surface; the center from the lens; l would be the distance from the center of + ) d will be the distance between the imaging position and also the center in the CMOS; and L could be the where is the angle in between the reference plane as well as the line within the or horizontal distance involving the laser and also the CMOS. the The coordinates of each and every point are connected accordingcenter correct topological ima center in the lens; l will be the distance from the for the of your lens for the connection to characterize the contour information and facts on the measured object within the present will be the distance among the imaging position as well as the center with the CMO section. TD139 References Thinking of the accuracy, robustness, and versatility of your extraction approach, the horizontal distance in between the laser as well as the CMOS. typically used procedures for extracting the centerline of laser stripes mostly include the gray centroid system, the Steger system, the Hessian matrix method, etc., which realize The coordinates of every single point are connected in line with the right micrometer-level sub-pixel extraction accuracy [10,11]. At present, the newest study in this object lationship to characterize the contour information and facts on the measured field has created particular adjustments for the classic algorithms mentioned above for distinct section.
