In agriculture the main ones are collision avoidance, human-machine safety - detecting and computing distance to an object nearby, then crop analysis - counting, measuring the dimensions and estimating ripeness. Warehouse adds use-cases such as inventory tracking, through volume estimation and barcode reading. Navigation (stereo VSLAM is more robust than mono), bin-picking, palletization, free-space estimation for cargo load. Those and many more require accurate depth estimation and strereo vision is the most universally applicable way of doing it, while being accurate and fast enough!
