Title:
CALIBRATION METHOD AND APPARATUS FOR TARGET SHOOTING DEVICE, AND TARGET SHOOTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066077
Kind Code:
A1
Abstract:
A calibration method for a target shooting device (200), comprising: step 110, configuring a light beam emitting apparatus (205) for calibrating a target shooting device (200), such that the irradiation direction of a light beam emitted by the light beam emitting apparatus (205) points to an image acquisition field of view of an image acquisition apparatus (204), and acquiring a plurality of target images (400) which are acquired by the image acquisition apparatus (204) and which correspond to a target being located at different target shooting distances; step 120, according to a light spot image (402) formed by the irradiation of the light beam emitting apparatus (205) in each target image (400), and the target image (400), acquiring a preset direction aiming pixel deviation corresponding to each target image (400); step 130, on the basis of the preset direction aiming pixel deviation corresponding to each target image (400) and the radius of a target surface image (401) in the target image (400), performing fitting to obtain a mapping relationship between the preset direction aiming pixel deviations and the radiuses of the target surface images (401) in the target images (400); and step 140, according to the mapping relationship, calibrating image center points (403) of the target images (400) acquired during target shooting. Further provided are a calibration apparatus for a target shooting device (200), a target shooting device, an electronic device, and a computer-readable storage medium.
