Abstract

The invention discloses a parameter acquisition method and terminal equipment, relates to the technical field of communication, and aims to solve the problem that the calibration of a distance sensoris relatively complex. The method comprises the steps of obtaining a preview image of a target object in a shooting preview interface; when the coincidence degree of the preview image and a calibration area in the shooting preview interface exceeds a threshold value, obtaining a first measurement value of a distance sensor; and obtaining a calibration offset corresponding to the target object based on the first measurement value and the calibration distance. According to the embodiment of the invention, the calibration complexity of the distance sensor can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for acquiring parameters and a terminal device. Background technique [0002] With the advancement of sensor technology, cameras of some electronic products can use distance sensors to measure the distance of the focus object in order to achieve more accurate focus. For example, a currently popular solution is to measure the straight-line distance between the focused object and the camera by using a time of flight (Time of Flight, TOF) technology, that is, the focused object distance. [0003] Although distance sensors based on technologies such as ToF have high ranging accuracy, they have poor adaptability to the environment. Not only electronic products need to calibrate the ranging accuracy of the distance sensor before leaving the factory, but also after electronic products are repaired or used for a period of time, they also need...
