Embodiment 1

[0031] see figure 1 As shown, a lane line detection method based on morphological reconstruction includes:

[0032] S101: Perform image processing on the acquired road surface image to obtain a suspected vehicle area;

[0033] S103: Perform vehicle detection on the suspected vehicle area by using a preset detection model, and obtain initial position and distance information of each vehicle in the suspected vehicle area;

[0034] S105: Evaluate the initial position and distance information of each vehicle through a stability evaluation algorithm, and obtain an evaluation result;

[0035] S107: Judging whether the evaluation result meets the preset standard, and when the evaluation result meets the preset standard, activate the tracking algorithm for each corresponding vehicle to perform tracking detection.

[0036] Specifically, before performing step S101, first initialize the vehicle detector and load the preset detection model; wherein, the vehicle detector has a built-in ...

Abstract

The invention discloses a disparity-map-based real-time vehicle tracking and detection method and device. The real-time vehicle tracking and detection method comprises: carrying out image processing on an obtained pavement image to obtain a suspected vehicle area; carrying out vehicle detection on the suspected vehicle area by a preset detection model to obtain initial position and distance information of each vehicle in the suspected vehicle area; evaluating the initial position and distance information of each vehicle based on a stability evaluation algorithm to obtain an evaluation result;determining whether the evaluation result meets a preset standard; and if so, carrying out tracking and detection on all corresponding vehicles by starting a tracking algorithm. According to the invention, on the basis of a disparity map, real-time tracking and detection of a vehicle is realized under the circumstance that the computing resources are limited; and thus the real-time performance andstability of positioning are improved on the premise that the vehicle detection precision is ensured.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a method and device for real-time vehicle tracking and detection based on a disparity map. Background technique [0002] In recent years, with the improvement of my country's highway transportation network, the vigorous development of logistics, and the improvement of people's living standards, people will become more and more inclined to choose vehicles for travel or transportation, resulting in more and more vehicles driving on the road . During the driving process, the driver will be fatigued, the road surface environment will continue to change, and the impact of weather factors such as changes in light intensity, cloudy days, and haze will pose a great threat to the safe driving of the vehicle. Extreme conditions may also lead to safety accidents, resulting in loss of life and property. In order to solve this problem that plagues the safe driving of cars, t...
