Description

Technical Field

[0001] This invention relates to the field of vehicle identification technology, and specifically to an adaptive light-changing interactive method for automotive luminous identification. Background Technology

[0002] Adaptive optics, a method to improve image quality by correcting wavefront distortion in real time, was first proposed by Julius Babcock in 1953. Its core components include a wavefront sensor, deformable mirrors, and a control system, and it is primarily used in fields such as astronomical observation and laser fusion. With technological advancements, photorefractive adaptive heterodyne detection technology has gradually emerged. This technology, based on atmospheric optics principles, can be used to measure optical parameters such as atmospheric transmittance and turbulence.

[0003] However, existing technologies in the field of human-computer interaction have significant shortcomings. Traditional display systems and interaction methods have failed to effectively address the problems caused by changes in ambient light. For example, Chinese Patent 01128777.2 discloses a photorefractive adaptive heterodyne detection method, which suffers from low signal-to-noise ratio and difficulty in adjusting the optical path. In practical applications, ambient light interference leads to inaccurate interaction data, especially in mobile devices and augmented reality scenarios, where rapid changes in lighting conditions severely impact the user experience.

[0004] Current adaptive optics technologies primarily focus on specialized measurement fields. For example, while pulsed laser photorefractive detection technology can measure optical parameters along atmospheric propagation paths, it is not optimized for human-computer interaction scenarios. Although graphics processing technologies such as adaptive temporal anti-aliasing (ATAA) can solve some rendering problems, their adaptability to real-world lighting changes remains insufficient.

[0005] Especially in varying lighting environments, existing interactive systems lack the ability to perceive and adaptively adjust to the lighting environment in real time, resulting in problems such as poor visibility of displayed content, low accuracy of gesture recognition, and failure of eye tracking. These shortcomings limit the application of human-computer interaction technology in outdoor scenarios and across different lighting conditions, and there is an urgent need for an innovative method that can perceive changes in ambient light in real time and dynamically adjust interaction parameters. Summary of the Invention

[0006] In view of the above problems, the purpose of this invention is to provide an adaptive light-changing interaction method for automotive luminous signs, which can more flexibly and efficiently adapt to various complex environmental conditions, significantly improve imaging quality and user experience, and overcome the shortcomings of the prior art.

[0009] Step S2: The central processing unit performs data sampling and analysis every 100ms;

[0010] Step S3: Detect changes in ambient light in real time using the light sensing module. When the ambient light exceeds the threshold or a user interaction signal is received, start ambient light adjustment.

[0019] Step S84: Multi-user priority management. When the light sensing module detects multiple users, the central processing unit automatically allocates lighting control rights based on user identity and activity importance.

[0020] Step S85: Haptic feedback adjustment. When the capacitive touch sensor of the interactive recognition module dims the area, haptic feedback is provided through a micro vibration motor to enhance the interactive experience.

[0022] Step S91: Use the neural network algorithm module of the central processing unit to predict ambient light and pre-adjust the light source 0.5-2 seconds in advance to eliminate the response delay of traditional systems;

[0023] Step S92: Analyze the user's subtle adjustment habits to the light environment using an ambient light sensor array, a human infrared sensor, and a camera to establish a personalized light environment mode;

[0024] Step S93: Using the adaptive light source module, a zone-based independent control mode is adopted to control the differentiated lighting information in different locations within the space to meet the different needs of multiple people;

[0025] Step S94: Use the central processing unit to detect user attention and automatically reduce the frequency of interfering light changes when the user is focused on work.
