IMAGE APPRATUS AND METHOD FOR CALCULATING DEPTH

摘要

An image apparatus may be configured to calculate a depth of an object relative to the image apparatus. The image apparatus may include an image sensor that may capture a plurality of images of the object. Depth calculation may include calculating a binocular disparity using the plurality of images, measuring a local temperature value from at least one temperature sensor, correcting a focal length of at least a portion of the image apparatus according to the measured local temperature value, and calculating a depth of the object using the binocular disparity and the corrected focal length. The corrected focal length may be determined based on a focal length variation value. The focal length variation value may be determined based on performing contrast autofocus on one or more captured images and the local temperature value.

1. A method for calculating a depth of an object relative to an image apparatus, the image apparatus including a depth pixel array, the depth pixel array including a an image pixel, the image pixel including a left pupil sensor and a right pupil sensor, the method comprising:
generating a left image of the object at the left pupil sensor; generating a right image of the object at a right pupil sensor; calculating a binocular disparity of the object based on the left image and the right image; measuring a local temperature value associated with the image pixel; calculating a corrected focal length associated with the image pixel based on the measured local temperature value; and calculating the depth of the object relative to the image apparatus, based on both the binocular disparity and the corrected focal length.
