Kinect传感器的植株冠层三维数据测量
Measurement and 3D-reconstruction of plants based on Kinect sensor
摘要
Abstract
The image reconstruction for three dimensional (3D) plant structures could be used to monitor plant growth automatically and provide real-time spray amount information for precision agriculture. A 3D image reconstruction method based on Kinect sensor technology was proposed to measure canopy stereoscopic structures. The color images and depth images of plants were detected with a Kinect sensor at the same time. The depth distances between objects and sensor were obtained based on average calculations after multiple depth image measurements. The horizontal projection area of plants and 3D canopy structure reconstructions of plants were achieved by extracting useful data and fusing color image and depth image information. Some regular-shaped objects and irregular-shaped plants were chosen as scanning targets to test the accuracy of the proposed method for depth distance and horizontal projection area estimation. The experiment results showed that the new method could detect both regular-shaped objects and irregular-shaped plants accurately with depth distance error less than 1.0% and horizontal projection area error less than 3.6% in all three depth detection distances from 1.1 m to 1.3 m. A planting area for potted chlorophytes in a greenhouse were used as scanning targets to verify the performance of the new method for detecting depth distances, measuring horizontal projection area, and reconstructing 3D canopy structures in real time. A 3D image detection and reconstruction system integrated with a Kinect sensor measuring mechanism and a position controller was used to conduct the experiments. The experiment results showed the average depth distance error was less than 1.77% and the proposed method has a high feasibility for 3D canopy structure measurements of greenhouse plants.关键词
