A fusion method of short-range hyperspectral camera and ranging sensor

Abstract

The invention discloses a fusion method of a short-range hyperspectral camera and a ranging sensor, which specifically includes the following steps: S1, designing a sensor mounting bracket and installing a hyperspectral camera and a ranging sensor; S2, designing a three-dimensional calibration checkerboard to make The reference points have different depth information; S3, use an external computer to collect the information of the hyperspectral camera and the ranging sensor at the same time, and the three-dimensional checkerboard is in a static state when collecting the information of the ranging sensor; S4, combine the hyperspectral camera with the ranging sensor The measurement information of the sensors is unified into the system coordinate system to establish the correlation between the sensors; S5. Based on the line push-broom hyperspectral camera calibration model, the fusion model of the hyperspectral camera and the ranging sensor is established, and the direct linear transformation DLT method is used to carry out the fusion model. Solve. The invention has higher resolution and precision, and integrates spectral information and spatial information, thereby providing a possibility for building a three-dimensional spectral model.

Description

technical field [0001] The invention belongs to the field of hyperspectral imaging technology and three-dimensional reconstruction technology, and particularly relates to a fusion method of a short-range hyperspectral camera and a ranging sensor. Background technique [0002] With the development of science and technology and the deepening of people's cognition of things, the research on modern agricultural development needs more and more information. However, due to the polymorphism and complexity of plants, two-dimensional images of plants captured by traditional methods can no longer meet the needs of research. Dynamically obtaining a large amount of spectral information of plants through hyperspectral imaging technology and visually presenting 3D models of plants through 3D reconstruction technology have become more and more research hotspots. [0003] Among them, hyperspectral imaging technology is currently applied in the fields of agricultural remote sensing identifi...
