FIELD OF INVENTION:
[001] The present invention relates to the field of driverless vehicle. The present invention in particular relates to a system and method for visibility enhancement during emergency evacuation in trains.

[003] Reference may be made to the following:
[004] Publication No. US7972045 relates to a vehicle headlamp control system includes an imaging sensor and a control. The control processes data from the imaging sensor and generates at least one control output. Selection of a high beam state and a low beam state for a vehicle headlamp is responsive to the control output, and is determined responsive to a detection of an object of interest. The control is responsive to a signal indicative of a vehicle speed of the controlled vehicle, and inhibits adjustment of the vehicle headlamp from a low beam state to a high beam state when the vehicle speed is below a threshold speed level. The control is responsive to data indicative of a vehicle trajectory of the controlled vehicle, and inhibits adjustment of the vehicle headlamp from a low beam state to a high beam state when a radius of curvature of the vehicle trajectory is below a threshold value.
[005] Publication No. FR2936195 relates to the method involves detecting lighting objects e.g. standing lamp, by determining a region of interest in an image acquired by a video camera of a vehicle, by extracting objects in the region of interest, and by selecting the extracted objects having a size higher than a determined size. The extracted objects correspond to successive pixels having a value higher than a grey level. A lighting mode of a headlight of the vehicle is determined with respect to the selected objects corresponding to the lighting objects, and proper parameter e.g. flywheel angle and speed, of the vehicle. An independent claim is also included for a device for adjusting lighting of a headlight for a motor vehicle, comprising a control unit.
[006] Publication No. FR2936194 relates to the method involves determining lighted zones during night through lighting objects e.g. standing lamps, by determining a region of interest in an image acquired by a video camera of a motor vehicle and by measuring a lighting degree in the region of interest. A lighting mode of a headlight of the motor vehicle is determined with respect to the lighting degree. The measurement of the lighting degree is carried out based on criterion of luminance amplitude in the region of interest, where the amplitude is calculated based on an average value of a value of pixels of the region of interest. An independent claim is also included for a device for adjusting lighting of a headlight for a motor vehicle, comprising a control unit.
[007] Publication No. EP1504957 relates to a control system to control the brightness of headlamps of a vehicle comprising: an image array sensor including a matrix of pixels, and an imaging system configured to image the scene forward of the controlled vehicle onto said image array sensor, wherein said image array sensor contains additional rows and columns of pixels to compensate for imperfections in aiming the imaging system relative to the controlled vehicle, and wherein the image array sensor is aimed through a portion of the controlled vehicle windshield cleaned by a windshield wiper.
[008] Publication No. CN103517532 relates to an LED automobile headlight with adjustable brightness and color temperature. The LED automobile headlight comprises a working power supply, a protective circuit, a control circuit, a sampling circuit, an LED array and a Buck-Boost circuit; the working power supply, the protective circuit, the Buck-Boost circuit and the LED array are connected with one another sequentially; the input end of the sampling circuit is connected with the LED array, and the output end of the sampling circuit is connected with the control circuit; the output end of the control circuit is respectively connected with the protective circuit and the Buck-Boost circuit; the LED array comprises a high-power blue light wafer, a medium-power yellow light wafer and a low-power red light wafer; fluorescent glue is adopted to realize surface packing of the LED array; the blue light wafer, the yellow light wafer and the red light wafer are connected in parallel to form three circuit loops. The automobile headlight can meet requirements of the automobile headlight on various luminous conditions, and is adjustable in brightness and color temperature, reasonable in design logic, safe, reliable, and low in manufacturing cost.
[009] Publication No. CN209225052 relates to a driverless vehicle driving control system with a variable headlamp. The device comprises a sensor unit, a core unit and a light emitting unit, the sensor unit comprises an identification sensor for detecting road conditions; wherein the core unit comprises a sensor fusion algorithm module, a scene analysis module, a prediction and decision module for predicting a vehicle driving state, a target calculation module and the like; the light emitting unit comprises an automobile headlamp; a running automobile passes through the road condition recognition sensor. The system detects road conditions on a road, performs real-time scene analysis and monitoring, recognizes a road user or an obstacle, observes and calculates a target, predicts a to-be-generated condition, makes a decision of a driving strategy, controls left and right headlamps to output corresponding light illuminance according to a result, and meets the illumination requirements of a sensor.
