This invention belongs to the field of optical component mounting technology, specifically a real-time coaxial optical coupling loss detection and alignment system for prisms and lens arrays. It includes an automatic loading and unloading module for automatically loading the substrate, prisms, and lens arrays, and automatically sorting and unloading qualified and unqualified products. By adopting a technical solution that uses the real-time coaxial optical coupling loss detection value as the sole criterion for final alignment of the lens array, combined with a graded alignment strategy of visual coarse alignment and coaxial optical fine alignment, it solves the common industry pain point of existing pure visual alignment and passive alignment technologies that separate physical dimensional accuracy from optical performance. This results in the inability to compensate for manufacturing errors such as uneven refractive index and surface flatness deviations within optical components, leading to substandard optical performance despite meeting physical accuracy standards and low yield rates in mass production. By using dimensional and angular tolerances only as auxiliary constraints, it directly locks the global minimum coupling loss point, improving the consistency and stability of the product's optical performance.

The map rendering method comprises: obtaining boundary information of at least two to-be-drawn map regions; determining a map tile covering the to-be-drawn map region based on the boundary information of the to-be-drawn map region; for each to-be-drawn map region, rendering using a same source map tile; and when the range of the map region rendered by the map tile is greater than the range defined by the boundary of the to-be-drawn map region, making the region outside the boundary of the to-be-drawn map region invisible. The scheme provided by the embodiments of the present application avoids the problem that the overlapping parts of the map tiles corresponding to different sources affect the display effect.
