Patent KR-20210128656-A (KR)
Inventor: HONG KYUNG EUI
IPC: G01B11/02
Filed: 2020-04-17
Abstract: One embodiment of the present invention relates to a distance measurement device, and more specifically, to a distance measurement device to which an upper edge detecting method is applied, and which may comprise: a sensor module of a time of flight (TOF) method, comprising a light emitting unit projecting light towards an object, and a light receiving unit receiving the light reflected from the object; a controller unit which calculates a distance value between the sensor module and the object based on the characteristics of the received light; and a converter unit which converts the distance value into an analog signal to generate an output value. The controller unit generates a first output value to be proportional to the distance value in case the distance value is within a predetermined first distance value range, and, in case the same is out of the first distance value range, controls the converter unit to generate a second output value or a third output value which are different from each other. The characteristics of the light include characteristics related to the difference between the first time during which the light emitting unit projectes the light towards the object, and the second time during which the light receiving unit receives the light reflected from the object. The controller unit calculates the difference between the first time and the second time based on the difference between the phase of the light projected by the light emitting unit and the phase of the light received by the light receiving unit to produce the digitized distance value. The first time is the time during which the upward edge of the light projected by the light emitting unit is detected, and the second time is the time during which the upward edge of the light received by the light receiving unit is detected. Therefore, precision in distance measurement can be increased.
