Estimating crop mass using x-ray scanner
A recently granted patent (Publication Number: US11927551B2) discloses a method for estimating the weight of plants, particularly focusing on plants organized in rows with fruit-bearing portions. The method involves irradiating the plants with X-rays from opposing sides, obtaining scan images, correlating and isolating fruit-bearing portions, aligning images, and estimating weight based on the aligned images. Additional steps include enhancing contrast, de-noising, processing images, and applying corrections based on intensity ratios. The method also involves flipping visuals, isolating fruit-bearing portions by discarding edges, determining GPS coordinates, normalizing images, and analyzing data at pixel and feature levels.
Furthermore, the patent claims involve determining GPS coordinates, locating rows of plants, transforming rows in a predefined direction, and processing images using cluster segmentation methods. The weight estimation is based on X-ray backscatter signals proportional to fruit mass and distance from the X-ray source. The method includes dual-view data acquisition, deep learning algorithms for cluster identification, and annotating clusters. The scan images are obtained along angularly displaced planes, with parallel or angularly displaced planes ranging between 90 to 270 degrees. The method can use two X-ray scanners simultaneously or one X-ray scanner for obtaining scan images. Corrections are applied for contrast, brightness, intensity, or scale, and weight estimation involves identifying fruit clusters and analyzing intensity pixel by pixel over time. The patent provides a detailed and innovative approach to estimating plant weight using X-ray technology, with various steps and techniques to enhance accuracy and efficiency in agricultural applications.
