In high-precision sorters, in order to achieve multi-angle detection, generally, the measure of arranging multiple cameras at different angles is adopted. Multiple cameras image the same seed, requiring a high degree of timing consistency and posing a very high requirement for the stability of the hardware system, resulting in a high maintenance cost.
