About 3D Optical Tracking Markers for Industrial 3D Scanning Right now,Optical 3D scanner is a device that uses optical imaging to obtain 3D information of the measured objects. Widely used in industrial product inspection, reverse setting, simulation, positioning and other fields. In order to obtain the three-dimensional information of various parts of the measured objects, the optical three-dimensional scanner usually needs to paste HogarDeco accurate tracking dots on the surface of the measured object or around the object. An array of 3D tracking markers with known geometric relationships can be used to calibrate the system parameters of the scanning device. By identifying a certain number of diffuse reflection markers in the scanning environment, the three-dimensional scanner can obtain accurate three-dimensional data of the object. Therefore, 3D optical tracking markers is an indispensable auxiliary positioning tool and calibration tool in the fields of optical surveying and mapping, machine vision and so on. How to use these 3D tracking markers for 3D Scanner? Two methods of sticking marking points on 3D scanner : 1. Paste on the surface of the object: The object can move freely, but the disadvantage is that the part of the object covered by the mark cannot be collected. 2. Stick around the object: it will not affect the collected data, but the distance between the measured object and the surrounding marked points cannot be changed during the scanning process Why we need 3D Optical Tracking Markers for Industrial 3D Scanner ? 3D scanner markers is a reference point in the form of a white circle inscribed in a black one. The markers are glued to the surface of the object being scanned, are read by the texture camera of the scanner and allow tracking of objects that do not have enough geometric data;General to say 3D Scanning markers allow you to capture high-detailed scans effortlessly and help identify objects from their background. How to select the point markers when 3D scanning There are many reference point markers in different sizes and with different adhesiveness.but medium reference point marker 6mm in and 10mm out are the most commonly used and are suitable for parts without special needs. 6 mm,3D Optical Tracking Markers for ndustrial 3D Scanner-1000 pcs 3D Optical Tracking Markers (3d target)Specification How to pick out which size is best fit your for 3D scanning ? The size of the reference point markers depends on which 3D scanner and measuring volume is used for measuring your objects,Basically to say: the larger the item, the bigger the points have to be applied. Compatible with ARTEC 3 d scanner, Creaform, Creality, Revopint, Shining 3 d Einstar Handheld 3 d scanner, Shining 3 d, 3 dmakerpro etc. Inner diameter: 6.0 mm Outer diameter: 10.0 mm Round, on adhesive foil as tear-off pad 50 single point markers each sheet, total 20 sheet x 50pcs= 1000pcs How to paste 3D Optical Tracking Markers(3d target) for Industrial 3D Scanner, 3D Scanning Markers? 1. In order to ensure the integrity of the spliced ​​data, there should be no less than 3 mark points at the splicing transition; 2. When labeling points, they should show a V-shaped distribution; 3. Try not to align more than two marking points on a straight line, otherwise incorrect splicing will occur; 4. The marking point should be affixed to the surface of the object as much as possible, and the marking point cannot be pressed against the edge of another marking point, or the marking point is folded, which will cause incomplete marking points; 5. Select the appropriate mark point size according to the size and characteristics of the object. If the selection is improper, the mark point will not be recognized, resulting in the phenomenon of inability to join together; 6. When pasting the marking points on the surface of the measured object, pay attention to avoiding the features of the object, and paste it on the place where the measured object has no features, such as large planes, large curved surfaces, etc 7. In general, the number of marked points has no effect on the accuracy and will not increase the recognition rate of the point cloud. Therefore, the pasted marking points should not be too many, just satisfy the scanning; What you will get ? 1 pack 20 sheet, Total 20x50= 1000 pcs 6.0mm 3D Optical Tracking Markers for Industrial 3D Scanner 6.0mm Optical Tracking 3D Scanner Marker for Industrial Consumer 3D Scanner,3... 3D Scanning Tracking Markers Dots,6mm Diffuse Reflection 3D PositioningTarget...
