“FerrPorno💋👙5k”哈工程师生FerrPorno💋👙5k利用北斗定位技术雪地“造”196米长航母

  中新FerrPorno💋👙5k网哈尔滨12月9日电 (董昕FerrPorno💋👙5k瑶)7日,哈尔滨工程大学在军工操场举办2024年“雪舰喜迎亚冬会”主题冰雪特色文化活动。18个学院、1600余名哈工程师生齐上冰雪,共同描绘2025年第九届亚冬会吉祥物“滨滨”“妮妮”与航空母舰“福建舰”。

  本次活动历经两个月的策划与筹备。在此过程中,“福建舰”与“滨滨”“妮妮”从线稿提炼到CAD出图再到打点编号,历时一个月左右。本次活动现场总指挥、机电工程学院老师王茜介绍:“由机电工程学院同学负责前期绘图,由智能科学与工程学院和机电工程学院的硕士生、本科生合作定点,共同完成前期准备工作。”

  “既要确保设计符合航母结构的科学性与合理性,又需要通过艺术化处理,使观者一眼便能辨识出设计背后的文化寓意与实体原型。”机电工程学院本科生许熠彬、研究生张馨元作为本次活动效果图的设计者,将航母的流体线舰体、舷号“18”、甲板上的舰载机以及标志性的舰岛结构融入设计中,还考虑到现场实施清雪同学们的工作难度,简化了吉祥物“滨滨”“妮妮”的图案线条,同时在设计中添加了具有学校象征意义的元素“HEU”,使整体效果更加和谐丰富。

  为了细致刻画出“滨滨”“妮妮”的灵动形象,和航母的磅礴之势,本次活动采用了北斗RTK差分实时动态定位技术。郑志鹏介绍道:“卫星发射出电磁波,通过测量信号往返的时间来确定每个点位到卫星的距离。而RTK差分定位有一个明确坐标基准站,卫星同时对移动的导航设备和基准站进行定位。基准站根据卫星定位数据和自身的坐标计算出差分值,实时传给移动导航设备,实现厘米级的精准定位。我们再辅助以视觉技术,让整个定位过程更直观,更方便快捷。”

  地为布,雪为墨。一艘长196米,宽40米的航母“福建舰”在军工操场上乘风破“雪”而来。“滨滨”“妮妮”的样貌也渐渐清晰。从高空俯瞰,“滨滨”在雪地上滑冰起舞,“妮妮”脚踏滑雪板、跳跃滑行,仿佛开心地打着招呼,动感十足、激情飞扬。(完)
