Embodiment Construction

[0019] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures and techniques are presented for a thorough understanding of the embodiments of the present disclosure. It will be apparent, however, to one skilled in the art that the present disclosure may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.

[0020] figure 1 is a schematic diagram of calculating the coordinates of the target point based on the coordinates of the nearest reference point in the related art.

[0021] Such as figure 1 As shown, point A is the target point, its coordinates are (s, l), and point B is the nearest reference point found through traversal; during the conversion process from the Cartesian coordinate s...

Abstract

The invention relates to the technical field of unmanned driving, and provides an error compensation method and device, computer equipment and a storage medium. The method is applied to unmanned equipment, namely automatic driving equipment or an unmanned vehicle, and comprises the following steps: establishing a first coordinate system based on a reference point closest to a target point; acquiring a first coordinate of the target point in the first coordinate system and a second coordinate of the reference point in a second coordinate system; and calculating a third coordinate of the target point in the second coordinate system based on the first coordinate and the second coordinate so as to compensate a conversion error from the first coordinate system to the second coordinate system. According to the invention, the conversion error from the first coordinate system to the second coordinate system can be eliminated, and the conversion time consumption is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of unmanned driving, and in particular to an error compensation method, device, computer equipment, and computer-readable storage medium. Background technique [0002] Unmanned vehicles, also known as self-driving vehicles, unmanned vehicles or wheeled mobile robots, are integrated and intelligent new-age technology products that integrate environmental perception, path planning, state recognition and vehicle control. The vehicle is equipped with intelligent software and a variety of sensing devices to achieve the purpose of unmanned driving. [0003] In unmanned driving technology, trajectory planning, as a high-dimensional optimization problem with multiple nonlinear constraints, consumes a lot of computing resources, and due to the complexity and real-time nature of the scene, it is not always quick and easy to obtain The optimal trajectory, therefore, has high requirements on the robustness and...
