Abstract:
In one embodiment, a method for calculating a distance to an object includes simultaneously activating a first projection point and a second projection point of a distance sensor to collectively project a reference pattern into a field of view, activating a third projection point of the distance sensor to project a measurement pattern into the field of view, capturing an image of the field of view, wherein the object, the reference pattern, and the measurement pattern are visible in the image, calculating a distance from the distance sensor to the object based on an appearance of the measurement pattern in the image, detecting a movement of a lens of the distance sensor based on an appearance of the reference pattern in the image, and adjusting the distance as calculated based on the movement as detected.
