| description | The invention provides a line detection method and device and a depth calculation method and device based on a line light iTOF camera. The line detection method comprises the steps of obtaining an infrared amplitude image according to an original phase image collected by the camera; carrying out binarization processing on the infrared amplitude image, and then determining a connected region of which the pixel value is a target value; searching effective pixel points in a connected region on the infrared amplitude image, and obtaining a linear light region of the infrared amplitude image based on all the effective pixel points; and mapping the linear light area of the infrared amplitude image to the original phase image to obtain the linear light area of the original phase image. Through the implementation of the scheme of the invention, the effective pixel points in the connected region are searched for the infrared amplitude image corresponding to the original phase image, and then the linear light region fo |
