when faced with different complex industrial scenes, how to choose a suitable and cost-effective industrial-grade 3d camera has been plagued by many vision system integrators and end users. for example, the upstream and downstream logistics turnover of industrial parts generally adopts a larger and deeper material frame (≥l1200mm × w1200mm × h800mm), which requires the addition of a material frame lifting mechanism, a camera moving module or the use of multiple 3d cameras for stitching, which increases the cost of use , and too many system modules will also affect the efficiency and stability of the system. subject to factors such as application requirements, cost of use, and product performance, most of the 3d cameras at home and abroad cannot meet the requirements, but the cost of using a few 3d cameras that can meet this application background is not low.
