Embodiment

[0072] In this embodiment, two groups of photos during the movement of items are taken, including single item and multi-item cases, wherein the moving direction of the items in each group of photos is random. After target detection, the result is input into the corresponding implementation of the present invention, and the actual effect of the present invention is checked by comparing the recognized result of the present invention with the real moving direction of the object.

[0073] Such as figure 1 Shown is the composition of the detection frame obtained by object detection in the method of the present invention, wherein (x1, y1) is the coordinate of the upper left corner of the detection frame, (x2, y2) is the coordinate of the lower right corner of the detection frame, and prob is the object after the target detection The obtained probability list, i_frame is the frame number of the object;

[0074]Step 1: Define the detection frames of the continuous frames of object mo...

Abstract

The invention discloses a method for identifying the moving direction of an object based on target detection. The process is as follows: each moving track corresponds to the movement of an object, and every time a frame is recognized, all detection results of the frame are compared with all current moving tracks Full arrangement, and then remove unmatched motion trajectories according to conditions such as the minimum distance matching of the same item, and mark the detection results that do not match the current motion trajectory as the results to be matched, and wait for the next frame to continue matching. The movement direction of the item can be identified according to the movement trajectory. The method of the present invention has a good effect on discriminating the moving direction of the object.

Description

technical field [0001] The invention belongs to the technical field of visual target tracking, and relates to a method for recognizing the moving direction of an object based on target detection. Background technique [0002] In the era of intelligence where computers are prevalent and artificial intelligence technology is developing rapidly, the realization of computer vision-based object tracking technology is playing an increasingly important role in various industries. The main idea is to establish and track the positional relationship of the object in a continuous video sequence to obtain the complete trajectory of the object. According to the trajectory, the movement direction of the object can be quickly judged. During the movement of the object, the target may present some images. Changes in the environment, such as changes in the shape of objects, severe occlusions, or changes in light brightness, etc., all of which need to be resolved through target tracking and ta...
