Title:
レーザレーダシステムに基づく距離測定方法、レーザレーダシステムに基づく距離測定装置及びコンピュータ読み取り可能な記憶媒体
Document Type and Number:
Japanese Patent JP6835914
Kind Code:
B2
Abstract:
The present invention provides a ranging method based on a laser radar system, a device and a readable storage medium. The ranging method includes receiving ranging data obtained by measuring via a plurality of laser radars of a laser radar system, where the ranging data includes distances between the laser radars and obstacles in measurement ranges of the laser radars; establishing a three-dimensional coordinate model according to the ranging data; and determining a distance between a target unmanned device and each obstacle according to the three-dimensional coordinate model. The ranging method of the present application, in which establishing a three-dimensional coordinate model by using ranging data measured by a plurality of laser radars, and determining a distance between a target unmanned driving device and an obstacle according to the three-dimensional coordinate model, can realize a ranging calibration task for a larger distance range, thereby effectively improving a calibration efficiency and accuracy of the visual image algorithm, compared with the existing method of ranging calibration of the visual image algorithm by a single laser radar.
