北斗定位厘米级精准 哈尔滨工程大学千名师生铲雪造“舰”

Core Viewpoint - The event at Harbin Engineering University involved over 1,200 students and faculty members creating a giant snow sculpture of the "Fujian" aircraft carrier and three carrier-based aircraft, showcasing teamwork and engineering skills [1][3]. Group 1: Event Details - The snow sculpture project took place on December 28, with participants working for about one and a half hours to complete the 230 meters long and 112 meters wide design [1][3]. - The project was characterized by a collaborative effort, with sounds of shovels and brooms creating a lively atmosphere during the construction [1][3]. Group 2: Design and Technology - The design process began in September and involved over 60 iterations, utilizing a top-down three-dimensional composition to enhance visual impact [3]. - The final design included more than 1,300 feature points, representing a significant advancement in both visual representation and engineering practice [3]. - The CAD drawing team played a crucial role in extracting key contours and setting positioning coordinates for the construction, ensuring precision in the final output [3][5]. Group 3: Precision and Technology Utilization - The project employed Beidou satellite positioning technology to achieve centimeter-level accuracy in placing over 1,300 feature points on the construction site [5]. - Teams were organized into ten groups, each led by a graduate student, to accurately mark the designated points using real-time differential positioning technology [5].
