摘要:
基于ATM的思想为移动机器人探测狭窄环境提出了一种改进方法,使得在地图创建的精度上有一定的提升.虽然声呐传感器探测目标体的距离有较高的准确度,但声呐对目标的方位判断却存在一定的误差,借鉴了ATM的思想,所采用的声呐模型为均匀分布模型,设定了切线的角度变化范围并引入了权值,对目标的方位进行了误差修正,并且在MORCS-2机器人平台上进行了实时地图创建实验,验证了这种方法有着较好的精确性与可行性.
Abstract:
A method is p roposed for imp roving the accuracy ofmapp ing data generated bymobile robots by using the arc2transversalmedian (ATM) algorithm. Although sonar sensors can accurately determine the distance between objects and the robot, they can’t p recisely estimate the azimuth of the object. We used the uniform distribution mod2 el as our sonarmodel, in which the range of change of angle formed by two tangents was p rescribed, and weights were app lied. Finally, errorswere adjusted. Experimentswith real2time map buildingwere made on theMORCS22 robot p latform. They showed exciting and p romising results, and verified the accuracy and feasibility of the p ro2 posed method.
