Title:
IMAGE PROCESSING METHOD, CALIBRATION SYSTEM, AND RELATED EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2024/041202
Kind Code:
A1
Abstract:
An image processing method, applicable to an electronic equipment positioning scenario. The method comprises: acquiring a plurality of images, wherein each image comprises a calibration body and electronic equipment rigidly connected to the calibration body, and the electronic equipment is provided with a light point, and is internally provided with an inertial measurement unit (IMU) device; determining a first relative position relationship between the calibration body and the light point on the basis of the plurality of images; acquiring a second relative position relationship between the calibration body and the IMU device on the basis of the plurality of images and IMU data; and determining a third relative position relationship between the light point and the IMU device on the basis of the first relative position relationship and the second relative position relationship, wherein the third relative position relationship is used for positioning the electronic equipment. The calibration body rigidly connected to the electronic equipment is used as an intermediate medium to determine the third relative position relationship between the light point and the IMU device. Measurement data outputted by an IMU can be correctly represented on a coordinate system of a handle lamp point according to the third relative position relationship, so that the positioning precision of the electronic equipment is improved.
