AI Technical Summary
In existing technologies, existing image processing methods cannot effectively solve the problem of bulk material volume estimation in construction scenarios. Furthermore, existing methods for estimating bulk material volume in construction sites are susceptible to environmental shadows. Existing laser scanning and multi-view vision solutions are easily affected by dust, vibration, and complex lighting conditions, and have high deployment costs. Monocular vision solutions consume significant computational resources, and measurement results are easily affected by environmental shadows. Moreover, the surface textures and natural accumulation characteristics of different bulk materials vary significantly, resulting in insufficient measurement stability.
A multi-task joint prediction method is adopted. The bulk material images acquired by a monocular RGB camera are preprocessed, and a lightweight image semantic segmentation network is used to output a binary mask to construct a structured feature vector representing the distribution of bulk materials. The volume, loading rate, and bulk material category probability are predicted by a multi-task deep learning model, and the final correction is performed by combining the effective volume of the storage and transportation container.
It achieves high-precision, lightweight bulk material volume estimation at construction sites, can adapt to dusty and complex lighting environments, reduces computing resource consumption, improves measurement stability and response speed, and is suitable for resource-constrained edge computing devices.
