Abstract: High-speed and reliable imaging system is the foundation to realize correct fruit sorting. This paper introduces a multidirectional high-speed fruit imaging system, which can realize synchronic acquisition of multidirectional images of fruit surface. Multi-threads program structure is adopted to improve grabbing speed; single field grabbing mode is adopted to improve image quality. The performance of imaging system is tested with the developed intelligent fruit sorting experimental prototype, and the experiment result shows image quality and imaging speed can satisfy the requirements of real-time fruit sorting system.
