The embodiment of the invention provides a three-dimensional camera module, a terminal device and a distance measurement method. The three-dimensional camera module comprises a substrate, a first camera installed on the substrate and facing the first direction and a second camera installed on the substrate and facing the first direction, wherein the first optical axis of the first camera and the second optical axis of the second camera incline relative to the connecting line of the lens center of the first camera and lens center of the second camera, the first optical axis is opposite to a first included angle of the connecting line, the second optical axis is opposite to a second included angle of the connecting line, and at least one of the first included angle and the second included angle is not 90 degrees. The distance measurement accuracy of a long-distance object can be improved by obliquely arranging the cameras, achievement of the miniature and ultrathin three-dimensional camera module and the terminal device is facilitated, and portability is improved.
