Document Type and Number:
Japanese Patent JP7169835
Kind Code:
B2
Abstract:
To provide an electronic level capable of correcting noise due to sensitivity heterogeneity according to a temperature.SOLUTION: An electronic level (100) includes: an image sensor (20) which images a leveling rod pattern, so as to output imaging data as an electric signal; a temperature sensor (30) for measuring a temperature; a memory (71) for storing correction data set according to the temperature; and a processor (4) which selects the correction data according to the temperature, so as to correct the imaging data on the basis of the correction data.SELECTED DRAWING: Figure 4
