Abstract

The invention discloses a temperature drift correction method and system, terminal equipment and a computer readable storage medium, and the method comprises the steps: obtaining an initial parameter before zooming and a target parameter after zooming from a preset lens parameter two-dimensional array, determining a reference temperature drift coefficient proportion according to the initial parameter and the target parameter; and according to a preset lens parameter calculation rule, determining a curve of which the temperature drift coefficient proportion is closest to the reference temperature drift coefficient proportion in a preset zoom multiple-focus curve table as a target curve, and determining a temperature deviation value based on the target curve so as to perform temperature drift correction based on the temperature drift value. According to the invention, accurate correction of temperature drift can be realized.

Description

technical field [0001] The present invention relates to the technical field of temperature drift correction, and in particular, to a temperature drift correction method, system, terminal device and computer-readable storage medium. Background technique [0002] As the camera cools and heats up, the electrical characteristics of the camera's focus motor change, causing the focus to shift. For example, in manual focus mode, if the focus position just turned on is 1000, the actual focus position may become 1005 or 995 after half an hour, and the picture at this time will also become blurred. In theory, the position of the focus motor is fixed when it is adjusted to manual focus, so the essential reason for this phenomenon is that the temperature drift changes the electrical characteristics, resulting in a shift in the position of the focus motor. [0003] There are roughly two methods of temperature drift correction: one is to install a temperature sensor on the camera, the te...
