The present application proposes a lane marking detection method, device, electronic equipment and storage medium. Wherein, the method includes: inputting the acquired image to be detected into a preset target detection model, obtaining first detection information and second detection information of each grid in the image; Second, the detection information is subjected to non-maximum value suppression processing to obtain the position and category of each lane line boundary point in the image, the position of each lane center point, the corresponding lane width and the lane line category; according to each lane line boundary point in the image The location and category of each lane center point, the lane width corresponding to each lane center point, and the lane line category determine the lane line in the image and the category of each lane line. Therefore, through this lane line detection method, not only the accuracy and accuracy of lane line detection are improved, but also the robustness and accuracy of lane line type detection are improved.

The present application relates to the technical field of automatic driving, and provides a parking space recognition method, device, vehicle-mounted terminal and storage medium. In this application, the corner points of parking spaces are used as the core points of density clustering. Since adjacent corner points of parking spaces are connected by parking space lines, that is, there are detection points of parking space lines between adjacent corner points of parking spaces. Therefore, based on density The adjacent core points of each core point can be determined, and the parking corner points adjacent to each corner point of the parking space can be obtained. Using the characteristics that the adjacent corner points of the parking space are connected by the parking space line, the distorted parking space / special-shaped parking space in the image can be identified, and the parking space can be improved. recognition accuracy. In addition, using each corner point of a parking space as the core point of density clustering can ensure that when the parking space line near the corner point of the parking space is blocked and there are fewer detection points of the parking space line, the parking space corresponding to the corner point of the parking space can also be detected. If it is identified, the parking space inspection rate can be improved and the parking space missed inspection can be avoided.

The invention provides a people counting method and system thereof, belonging to the technical field of image processing. The method includes: performing frame-sequential object detection on a frame-sequenced image set, and when a first image with a first object set is detected in the image set, obtaining an image corresponding to the first object set in the first image The first local vector corresponding to the position of the first image, and then obtain the second local vector corresponding to the position of the second object set relative to the second image in the second image with the second object set in the image set; according to the first local The vector and the second local vector are combined with the preset tracking mapping relationship to obtain a tracking value set, and then according to the relationship between each tracking value in the tracking value set and the preset tracking threshold condition, a tracking state set of objects in the first object set is obtained. The invention realizes the detection and tracking of the high-accurate recall rate and realizes the high-precision and high-robust people flow counting system based on the detection and tracking of the high-accurate recall rate.
