Publication number: 20210120737Abstract: Systems and methods are disclosed herein for optimizing harvester yield. In an embodiment, a controller receives a pre-harvest image from a front-facing camera of a harvester. The controller inputs the pre-harvest image into a model, and receives as output from the model a predicted harvest yield. The controller receives, from an interior camera of the harvester, a post-harvest image including the plants as harvested. The controller inputs the post-harvest image into a second model and receives, as output, an actual harvest yield of the plants as-harvested. The controller determines that the predicted harvest yield does not match the actual harvest yield, and outputs a control signal.Type: ApplicationFiled: December 12, 2019Publication date: April 29, 2021Inventors: Dongyan Wang, Andrew Yan-Tak Ng, Yiwen Rong, Greg Frederick Diamos, Bo Tan, Beom Sik Kim, Timothy Viatcheslavovich Rosenflanz, Kai Yang, Tian Wu
