Abstract
The present application relates to a colorimeter measurement method and a colorimeter for implementing the method. The method includes the following steps: placing a measured sample on a sample platform; shooting a current image of the sample; determining an intersection angle θ between the sample and a moving direction of the sample platform; adjusting a position of a scanning light spot of a colorimeter according to the angle θ, so that the sample coincides with the moving direction of the sample platform; using the colorimeter to scan the measured sample. By implementing the colorimeter measurement method and the colorimeter of the present application, the sample can be placed optionally when it is measured. Specially, when a design value of a measured sample is approximately equal to a size of the measuring light spot, much time can be saved and manpower waste is avoided.
