Resumen
Este estudio presenta SafeDrive-Fusion, un sistema adaptativo para la percepción de la conducción autónoma. Mejora la seguridad vial en condiciones de poca luz fusionando dinámicamente datos visuales y de radar, mejorando la precisión y el reconocimiento de peligros.
Área de la Ciencia:
- Sistemas de conducción autónoma
- Visión por computadora y fusión de sensores
- Inteligencia artificial para el transporte
Sus antecedentes:
- La percepción de la conducción autónoma falla con poca luz (lluvia, niebla, noche).
- Los métodos de fusión multimodales existentes son estáticos y tienen dificultades con la iluminación variable.
- La evaluación robusta de la transitabilidad de la carretera es crucial para la navegación autónoma segura.
Objetivo del estudio:
- Desarrollar un marco de percepción multimodal adaptativo a la iluminación para la conducción autónoma.
- Mejorar la robustez de la percepción en condiciones adversas de poca luz.
- Mejorar el reconocimiento de regiones críticas para la seguridad y la evaluación de la transitabilidad de la carretera.
Principales métodos:
- Se propuso SafeDrive-Fusion: un marco de percepción multimodal adaptativo a la iluminación.
- Se implementó una fusión dinámica de atención intermodal con priorización de regiones críticas para la seguridad.
- Se introdujo un mecanismo de ponderación adaptativa para integrar dinámicamente datos visuales y de radar.
Principales resultados:
- Mantuvo una precisión del 87,5 % en condiciones de muy poca luz (degradación del 6,1 %).
- Logró una puntuación F1 de 0,82 para el reconocimiento de situaciones peligrosas (0,40 más que los valores de referencia).
- Demostró un ajuste dinámico del peso modal: el peso del radar aumentó del 25 % al 62 % a medida que disminuía la iluminación.
Conclusiones:
- SafeDrive-Fusion mejora significativamente la percepción de la conducción autónoma en entornos de poca luz.
- El marco de fusión y priorización adaptativa mejora la seguridad y la fiabilidad.
- El sistema cumple con los requisitos en tiempo real con una latencia de 45 ms.

Subliminal Perception
794
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Factors Affecting Perception
2.7K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Design Example: Alignment of a Road Line Using GIS
350
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Perception
1.2K
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Autonomic Nervous System
12.9K
The autonomic nervous system (ANS) is a critical component of the peripheral nervous system, primarily responsible for regulating involuntary bodily functions and maintaining homeostasis. It functions in tandem with the central nervous system (CNS) to seamlessly coordinate various physiological processes without the need for conscious control.
The ANS comprises two main divisions: the sympathetic and parasympathetic divisions. These divisions function antagonistically to maintain a dynamic...

Gestalt Principles of Perception
1.2K
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...
