Traditional autonomous intelligent vehicles rely on LiDAR systems that require multiple laser light sources, resulting in larger volume, higher power consumption, and increased costs, limiting their effectiveness in environmental observation and data acquisition for advanced driver assistance systems.
Innovation Solution
The integration of eye lamps equipped with a light emitting device and an image acquiring device, where the light emitting device includes a small-sized laser diode and adjustable beam angle, and the image acquiring device uses optical sensors and processors to directly acquire and process images, reducing the need for multiple laser sources and enhancing visual angle and cost efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If LiDAR system is used to acquire image data, then image acquisition capability is improved, but device volume increases
Solution Approach 1:
The patent combines the lighting function and image acquisition function into a single integrated lamp assembly. The lamp housing contains both the light emitting device (LED or laser diode) and the image acquiring device (camera module), merging two separate systems into one compact unit. This eliminates the need for separate LiDAR system while achieving both illumination and imaging capabilities.
Solution Approach 2:
The lamp assembly performs multiple functions: it provides lighting illumination through the light emitting device and simultaneously acquires image data through the image acquiring device. This multi-functional design replaces the specialized LiDAR system, reducing overall device volume while maintaining environmental observation capabilities.
2Measurement precision
If LiDAR system is used to form image through reflected laser, then image data is obtained, but power consumption increases
Solution Approach 1:
The patent merges the illumination source and image sensor into a single lamp assembly, allowing the system to use reflected ambient light or controlled LED illumination instead of requiring high-power laser sources. This integrated approach significantly reduces power consumption compared to traditional LiDAR systems while maintaining image acquisition capability.
Solution Approach 2:
The patent employs conventional LED or laser diode light sources with standard camera sensors rather than expensive, high-power laser systems. These components are more energy-efficient and cost-effective, providing sufficient performance for autonomous vehicle environmental perception without the high power demands of traditional LiDAR.
3Measurement precision
If multiple laser light sources are used in LiDAR system, then image formation capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent integrates the light emitting device and image acquiring device into a single lamp housing, eliminating the need for multiple separate laser sources required by traditional LiDAR systems. This consolidation uses conventional, readily available components (LEDs or single laser diode with camera), dramatically reducing manufacturing complexity and cost.
Solution Approach 2:
The invention replaces expensive LiDAR components with affordable, mass-producible alternatives. The lamp assembly uses standard automotive LED or laser diode technology combined with conventional camera modules, making the system economically viable for widespread autonomous vehicle deployment compared to costly LiDAR systems.
4Illumination intensity
If traditional vehicle lamps are used for lighting only, then lighting function is provided, but environmental observation capability is lost
Solution Approach 1:
The patent transforms traditional single-function vehicle lamps into multi-functional units. The lamp assembly simultaneously provides illumination through the light emitting device and environmental observation through the integrated image acquiring device, eliminating the need for separate observation systems while maintaining lighting performance.
Solution Approach 2:
The invention merges the lighting function and environmental sensing function into a single integrated lamp assembly. The lamp housing contains both the light emitting device (LED or laser diode) and the image acquiring device (camera module), allowing the same component to perform both illumination and observation tasks, thereby recovering environmental observation capability while maintaining lighting function.
