用卫星图像识别非洲盗猎热点,助力精准布防。

Poaching Hotspot Identification Using Satellite Imagery

  • 结合卫星影像与计算机视觉,识别盗猎高发区域的地理特征。
  • 揭示盗猎点随巡护密度、水源、季节等动态变化规律。
  • 适合野生动物保护机构和政策制定者参考部署资源。

非洲国家的大象盗猎问题已持续十年,导致非洲森林象被列为濒危物种,非洲草原象被列为极危物种。大象主要因象牙被猎杀,造成部分个体天生无牙以求生存。尽管盗猎手段未变,但盗猎地点随巡护强度、水源、季节、海拔等因素频繁转移。2000至2014年盗猎低谷期后,近年再次回升,世界自然基金会(WWF)估计每年有2万头大象遭盗猎。当前反盗猎力量集中于城镇附近,而多数盗猎发生在偏远地区。因此,亟需通过计算机视觉模型分析卫星影像,识别利于盗猎的地理特征,实现热点自动定位。该方法无需人工追踪,可跨区域大范围监测,且不干扰动物或突破空域限制。

原文摘要 · Abstract (English)

Elephant Poaching in African countries has been a decade-old problem. So much so that African Forest Elephants are now listed as an endangered species, and African Savannah Elephants as critically endangered by the IUCN (International Union for Conservation of Nature). [1] Elephants are hunted primarily for their ivory tusks which caused many elephants to be born tuskless as a genetic modification for survival. [2] Data gathered by recent studies shows that though poaching methods remain the same, the poaching grounds are rather dynamic. Poachers have shifted to areas with less ranger patrols and several other factors like watering holes, seasons, altitude etc. cause constant shifts in poaching hotspot locations. [3] After a period of low poaching from 2000-2014, poaching numbers in African countries are now on the rise again -- WWF (World Wildlife Foundation) says there are 20,000 elephants poached annually [4]. In African countries, anti-poaching efforts are concentrated near towns, while a majority of poaching occurs in the deserted regions. All of these factors result in the need for a Computer Vision Model to identify poaching hotspots through locating the geographic indicators of favorable poaching regions. A CV model eliminates the need to manually track poachers and account for the environmental factors to deploy resources and its combination with satellite imagery allows us to survey large areas without disturbing local species or cross border aviation restrictions.
