This paper presents new developments on drone-based automated survey for the detection of individual items or fragments of material culture visible on the ground surface. Since the publication of our original proof of concept, awarded with the Journal of Archaeological Science and Society for Archaeological Sciences Emerging Investigator Award 2019, additional funding has allowed us to implement a series of improvements to the method. These aim to improve detection capabilities and the extraction of items' shapes and increase flight autonomy, control, area covered per flight and the type of environments in which the method can be applied while reducing computing needs, processing time and expertise necessary for its application. This paper provides an account of the methods followed to achieve these objectives, their preliminary results and the current development for their implementation into a free and open-source system that can be used by the archaeological community at large.

基于无人机的自动地面测量的新发展：迈向功能性和有效的测量系统

本文介绍了基于无人机的自动调查的新进展，用于检测地表可见的单个物品或物质文化碎片。自从我们最初的概念证明发表以来，获得了 2019 年考古科学杂志和考古科学学会新兴研究者奖，额外的资金使我们能够对该方法进行一系列改进。这些旨在提高检测能力和物品形状的提取，并增加飞行自主性、控制、每次飞行覆盖的区域以及可以应用该方法的环境类型，同时减少其应用所需的计算需求、处理时间和专业知识。本文介绍了实现这些目标所遵循的方法，
