AI Technical Summary
Technical Problem
In existing technologies, reflectors need to maintain a unique shape for AGV positioning, making it difficult to deploy them on a large scale.
Method used
By identifying reflectors based on the intensity of laser reflection signals, and combining distance and angle constraints, the target reflector is matched from the pre-deployed reflectors. The position of the reflector is confirmed by using the interior angle of a triangle and multiple constraint methods, thus achieving precise positioning of the robot in world coordinates.
Benefits of technology
While ensuring precise robot positioning, the reflector shape and size are not unique, which increases the deployment range and improves the matching rate and positioning accuracy.

Abstract
本申请涉及机器人定位技术领域，尤其涉及一种反光板识别定位方法、装置、电子设备及存储介质，基于机器人接收到的激光反射信号的强度从其周边环境中识别出三个反光板，并得到所述三个反光板在机器人本体坐标系下的坐标；基于所述三个反光板两两之间的距离从预先部署的所有反光板中匹配出至少三个候选目标反光板；基于所述三个反光板两两之间的夹角从所述至少三个候选目标反光板中匹配出三个目标反光板，并且利用所述三个目标反光板得到所述机器人在世界坐标下的坐标。从而通过距离约束、角度约束的方式能够从数据库中准确匹配出所识别出的三个反光板，在保证机器人精准定位的同时，使得反光板的形状和大小无需保证唯一性，增加部署范围。
