Positive sample acquisition method and device for target detection, equipment and storage medium

[0034] figure 1 It is a flowchart of a positive sample acquisition method for target detection provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of screening samples for training models in image recognition, and specifically includes the following steps:

[0035] Step 1000, acquire an image to be detected, where the image to be detected includes at least one person image.

[0036] In this embodiment, the image to be detected is an image captured by a camera device for image recognition, which includes a person image or multiple person images. In an alternative embodiment, in addition to the person image, the image to be detected may also be an animal image, a vehicle image or other camera material images.

[0037] Step 1100, obtaining the anchor frame of the image to be detected.

[0038] In this embodiment, the target detection algorithm usually samples a large number of areas in the input image, and then judges whether these areas co

[0052] Please refer to figure 2 , figure 2 It is a flow chart of a method for obtaining positive samples for target detection provided by Embodiment 2 of the present invention. This embodiment optimizes and improves based on the solution of the first embodiment, and in particular provides a specific solution for matching rules between the anchor frame and the real label frame. Such as figure 2 As shown, the method includes:

[0053] Step 2000, acquire an image to be detected, and the image to be detected includes at least one person image.

[0054] Step 2100, acquire the anchor frame of the image to be detected.

[0055] Step 2200. Obtain the real annotation frame of the person image.

[0056] Similarly, step S2100 and step S2200 do not have a certain logical sequence relationship, step S2200 may be executed first and then step S2100 may be executed, or step S2100 and step S2200 may be executed simultaneously.

[0057] Step 2300, matching all the ground truth boxes with

[0070] Please refer to image 3 , image 3 It is a flow chart of a positive sample acquisition method for target detection provided by Embodiment 3 of the present invention. This embodiment optimizes and improves based on the solution of the first embodiment, and in particular provides a specific solution for filtering the first matching pair set according to the preset screening rules to obtain the second matching pair set. Such as image 3 As shown, the method includes:

[0071] Step 3000, acquire an image to be detected, where the image to be detected includes at least one person image.

[0072] Step 3100, acquire the anchor frame of the image to be detected.

[0073] Step 3200. Obtain the real annotation frame of the person image.

[0074] Similarly, step S3100 and step S3200 do not have a certain logical sequence relationship, step S3200 may be executed first and then step S3100 may be executed, or step S3100 and step S3200 may be executed simultaneously.
