The invention discloses an image acquisition device, eye refraction distribution measurement equipment and a measurement method thereof, the state of an imaging system is adjusted to an initial adjustment state according to the refraction condition of the fovea centrally fovea of the fundus of each subject, and then the imaging system is controlled according to preset scanning parameters by taking the initial adjustment state as a starting point, so as to obtain the refraction distribution of the eye. And the refractive distribution is measured according to the scanning parameters, so that the scanning range of the imaging system can be automatically adjusted according to the individual conditions of different testees, the time for measuring the refractive distribution of the eyes is greatly shortened, and the measurement efficiency is improved. 本发明公开一种图像获取装置、眼屈光分布测量设备及其测量方法，根据每一个被测者的眼底中央凹的屈光情况，将成像系统的状态调节到初始调节状态，而后，根据预设的扫描参数，控制成像系统以初始调节状态为起点，根据扫描参数进行屈光分布测量，如此，能够针对不同的被测者的个体情况，自动调整成像系统的扫描范围，大大缩短眼屈光分布测量的时间，提高测量效
