Vehicle parking detection method, preceding vehicle starting reminding method and storage medium

Abstract

The invention discloses a vehicle parking detection method, a preceding vehicle starting reminding method and a storage medium, and the method comprises the steps: carrying out the image preprocessingand region division: carrying out the preprocessing of an obtained image frame according to the image frame data, collected in real time, of a road in front of a vehicle, and dividing the image frameinto a plurality of regions; calculating a differential pixel ratio threshold value of each region; calculating the ratio of edge pixels in each region, and performing linear transformation on the ratio to adaptively obtain the differential pixel ratio threshold value of the corresponding region; performing difference operation between image frames: performing frame difference operation by usingthe current frame and the previous frame in each region based on the current frame to obtain a difference image of each region, and counting the proportion of difference pixels in the difference imageof each region; detecting and judging the state of each region: detecting the state of each region by respectively comparing the proportion of the differential pixel of each region with the proportion threshold of the differential pixel of the corresponding region; and judging whether the vehicle is in a parking state according to the states of the regions.

Description

technical field

[0001] The invention relates to the technical field of vehicle assisted driving, and in particular, to a method for detecting parking of an own vehicle, a method for reminding a vehicle in front to start, and a storage medium. Background technique

[0002] With the rapid development of urban road traffic system, the scene of urban road traffic is becoming more and more complex. Motor vehicle drivers will frequently encounter traffic control in the process of driving on urban roads, and the situation of motor vehicles lining up in long queues to stop and wait can be seen everywhere. Some existing parking waiting reminder systems use an intelligent control system to judge whether the car is parked, and to detect and judge whether the car in front is started on the basis of judging that the car is in a parked state, so as to realize the intelligence of the driver. Reminders to provide a more comfortable and secure driving experience.
