1Area of stationary object
If multiple optoelectronic systems are used to achieve both wide-angle viewing and high-resolution imaging, then the viewing angle and detection range are improved, but the device complexity and manufacturing costs increase significantly
Solution Approach 1:
The patent combines wide-angle viewing capability and high-resolution imaging capability into a single optoelectronic system by using a beam splitter to divide the light path, allowing one camera to perform functions that previously required multiple separate systems
Solution Approach 2:
The patent segments the light path using a beam splitter to direct different portions of light to different imaging paths, enabling simultaneous wide-angle and high-resolution capture within a single optoelectronic system
2Measurement precision
If multiple optoelectronic systems are deployed to meet opposing requirements of long-range and wide-angle detection, then the detection capabilities are improved, but the manufacturing costs increase due to the plurality of expensive optoelectronic components
Solution Approach 1:
The patent merges multiple detection functions into a single optoelectronic system, eliminating the need for multiple expensive cameras and reducing manufacturing costs while maintaining detection capabilities
3Measurement precision
If high-resolution image capturing sensors are used with wide-angle optical systems, then the image quality and detection range are improved, but the computational cost and processing complexity increase due to the large number of pixels
Solution Approach 1:
The patent applies different resolution requirements to different regions of the image by using a beam splitter to direct central high-resolution imaging to one path and peripheral wide-angle imaging to another path, allowing selective processing based on regional importance
