Early warning system for vehicle-mounted thermal imaging detection aiming at targets of different danger levels

Abstract

The invention discloses an early warning system for vehicle-mounted thermal imaging detection aiming at targets of different danger levels, and belongs to the field of vehicle-mounted thermal imagingdetection, the early warning system comprises a thermal imaging data module, the output end of the thermal imaging data module is electrically connected with a target detection module, the output endof the target detection module is electrically connected to a FrameBuffer, and the output end of the FrameBuffer is connected to a DRM module. Through conversion of a target relative position, threshold division of relative depth parameters and image expression and sound prompt of distance information, a target, especially a dangerous target, is reminded more remarkably and visually, so that a person can obtain target position information more visually, make a pre-judgment and avoid the target position information in advance. Light early warning in a low-risk state is achieved, and distractionto a driver at a low risk is reduced as much as possible; red early warning is performed at a high-risk moment, and high-decibel high-risk early warning is triggered; and the interference of false alarm triggering on a driver can be further reduced through light early warning.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted thermal imaging detection, in particular to a vehicle-mounted thermal imaging detection early warning system for targets of different danger levels. Background technique [0002] Vehicle-mounted target detection can help the driver assist in judging some dangerous targets that will affect driving, such as pedestrians, cars, bicycles and other dangerous targets. The existing vehicle-mounted thermal imaging night vision system will obtain target parameters from the target detection module, according to the target detection module. Regardless of the distance of the target, the target detection bounding box of the same type of target (pedestrian or bicycle, etc.) is drawn on the FrameBuffer with the same color, and then projected on the screen through the DRM system for display ; All detection targets will be prompted with the same warning sound. The current vehicle-mounted thermal imaging night vision...

AI Technical Summary

Problems solved by technology

The current vehicle-mounted thermal imaging night vision system cannot combine the different distances of dangerous targets to provide image and sound prompts for different danger levels. Too many early warnings for mild risky targets will distract the driver's attention, and the driver is prone to a single early warning method. Fatigue, ignoring high-level dangerous targets, based on a limited computing power platform, there is no early warning of different risk levels, which will trigger more false alarms and distract the driver's attention
