Problems solved by technology

However, when the SLAM positioning system performs positioning, it depends on the internal parameters of the sensors (referred to as internal parameters) and the external parameters between them (referred to as external parameters). If these internal parameters and external parameters are not calibrated correctly, it is likely to cause The positioning accuracy of the SLAM positioning system is reduced

Abstract

A detection method for positioning accuracy, an electronic device and a computer storage medium, the method comprising: controlling a target device to move according to a preset route (101); while the target device moves, detecting first location parameters of the target device by using a first positioning system in the target device, and detecting second location parameters of the target device by using a second positioning system (102); comparing the first location parameters and the second location parameters, and determining positioning accuracy of the first positioning system according to a comparison result (103).

Description

technical field [0001] The invention relates to positioning technology, in particular to a detection method for positioning accuracy and electronic equipment. Background technique [0002] The robot can locate the position of the robot in real time through multiple sensors, including: two-dimensional (2D) camera, three-dimensional (3D) camera, inertial measurement unit (IMU, Inertial Measurement Unit), etc., multi-sensor is also called synchronous positioning and mapping (SLAM, Simultaneous Localization and Mapping) positioning system. The SLAM positioning system can support many upper-level applications of robots and provide positioning functions for many applications. However, when the SLAM positioning system performs positioning, it depends on the internal parameters of the sensors (referred to as internal parameters) and the external parameters between them (referred to as external parameters). If these internal parameters and external parameters are not calibrated corr...
