This paper describes the initial results from the first of 3 years of planned testing aimed at developing methods, metrics, and targets necessary to develop standardized tests for these instruments. Here, we evaluate range error accuracy and precision for eight automotive grade lidars; a survey grade lidar is used as a reference. These lidars are tasked with detecting a static, child-sized, target at ranges between 5 and 200 m. Our target, calibrated to 10% reflectivity and Lambertian, is a unique feature of this test. We find that lidar range precision is in line with the values reported by each manufacturer. However, we find that maximum range and target detection can be negatively affected by presence of an adjacent strong reflector. Finally, we observe that design trade-offs made by each manufacturer lead to important performance differences that can be quantified by tests such as the ones proposed here. This paper also includes some lessons learned, planned improvements, and discussion of future iterations of this activity. |
