PROBLEM TO BE SOLVED: To provide a method and an apparatus for temperature measurement, where the temperature of a measuring object in a fluidized-bed furnace can be measured at low costs and with proper accuracy. SOLUTION: At temperature measurement in the fluidized-bed furnace 11, the inside of the furnace 11 is imaged by an imaging means, the temperature of the measurement object B is calculated, on the basis of the image obtained, and the calculated measured temperature is corrected by a prescribed correction expression.
