Method and device for correcting distance measured by distance measurement device according to temperature

The invention discloses a method and a device for correcting a distance, measured by a distance measurement device, of an object to be measured according to ambient temperature. The method comprises the following steps of: supplying a temperature sensor to measure the ambient temperature of the distance measurement device; calculating a corrected imaging position according to the ambient temperature and an imaging position of the distance measurement device during distance measurement; and calculating a corrected distance to be measured according to the corrected imaging position. Therefore, when the distance measurement device measures the distance, an error caused by change of the ambient temperature can be avoided according to the correction method.
