A three-dimensional laser scanning method applied to potted plants

Abstract

The invention discloses a three-dimensional laser scanning device applied to plant potting and a scanning method thereof. Because of many pointed parts caused by lots of leaves of the plant, defectivepixels occur frequently when the conventional scanning device carries out scanning, so that the scanning accuracy is low. Therefore, the invention provides a three-dimensional laser scanning device comprising a worktable, a rack, a first turntable, a second turntable, a slide rail, a sliding block, a first synchronization belt wheel, a first synchronization belt, a laser sensor, a scanning table,a first motor, a drive assembly, and a third motor. The first turntable and the second turntable that are supported at two ends of the rack respectively share the same axis and are arranged horizontally. The scanning table is fixed on the worktable; and the top surface of the scanning table is flush with the axes of the first turntable and the second turntable. According to the invention, with the three-dimensional laser scanning device, potting scanning and model establishment can be completed automatically; the shape of the potted plant can be restored completely by the established model; and occurrence of lots of defective pixels among scanning data corresponding to the surrounding of the pointed part of the potted plant is avoided.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional scanning, and in particular relates to a three-dimensional laser scanning method applied to potted plants. Background technique [0002] At present, most of the devices for plant morphology detection use nuclear magnetic resonance, CT imaging and other methods to obtain tomographic images of the parts to be scanned, and then obtain the morphology of plants by building a three-dimensional model. But the cost of the instruments used in this part is very high, and the consumable materials are expensive. There is also a method of using camera visual calibration to obtain plant models, which is slightly cheaper in terms of device cost, but the processing process is still relatively cumbersome. It needs to collect images, obtain a series of parameters through camera calibration, extract a series of image contours, and establish a point cloud model. Wait for the process. Since plants have a l...

There is also a method of using camera visual calibration to obtain plant models, which is slightly cheaper in terms of device cost, but the processing process is still relatively cumbersome. It needs to collect images, obtain a series of parameters through camera calibration, extract a series of image contours, and establish a point cloud model. Waiting for the process

Because plants have a large number of leaves, resulting in many sharp points, conventional scanning devices are prone to bad spots when scanning, and the scanning accuracy is low
