This article explains the importance of high contrast sticky targets in the context of surveying and terrain modeling.
3D scanners have revolutionized surveying and mapping by providing a fast and accurate solution for measuring the shapes, dimensions and details of any object or terrain. However, to obtain accurate and reliable data, it is essential to have high contrast sticker targets, usually in the form of checkerboard patterns in white and black.
Here are some reasons why high contrast sticky targets are so important in the 3D laser scanning process:
Self-adhesive targets provide a clear reference for scanning. 3D scanners measure distances between the scanned object and the scanner itself. Self-adhesive targets provide a clear, easily detectable reference for the scanner, helping to ensure data accuracy.
High-contrast self-adhesive targets overcome the challenges of detecting reflective and transparent surfaces. Reflective or transparent surfaces can reflect the laser beam, making accurate scanning difficult. High contrast self-adhesive targets provide an easily detectable surface, allowing the scanner to accurately measure distances.
Sticky targets are essential for aligning scans from different viewing angles. When multiple scans are taken of terrain or an object, it is important to align them correctly to obtain an accurate model. Self-adhesive targets accomplish this task with high precision, ensuring that the data is correctly aligned.
Sticky targets are a key element of terrain modeling. When several surveys are carried out on a site, the targets allow all the surveys to be aligned to make one. This creates an accurate 3D model of the terrain, which can be used for planning and design.
In conclusion, high contrast sticky targets are essential for 3D laser scanning in surveying and mapping. They provide a clear and easily detectable reference for the scanner, overcome the challenges of detecting reflective and transparent surfaces, facilitate scan alignment and are a key element of terrain modeling. Without high-contrast sticker targets, the accuracy and reliability of scanned data would be significantly reduced.
