Title:
測距装置及びその制御方法
Document Type and Number:
Japanese Patent JP7431193
Kind Code:
B2
Abstract:
In a distance measurement device that measures a distance to an object based on a time of flight taken until irradiation light is reflected by the object and returns to the distance measurement device, a brightness measurement unit measures an exposed electric charge amount as a brightness while a shift amount of an exposure gate is changed by an exposure gate shift control unit, and a light emission and exposure timing of another distance measurement device is set to a shift amount of the exposure gate where the brightness is maximized. The brightness measurement unit calculates a variation in the brightness of the exposed electric charge amount while the cycle of the exposure gate is changed, and it is determined that ½ of a value of the cycle of the exposure gate when the variation is minimized is a light emission cycle of the another distance measurement device.
