Distance measurement apparatus and method
A distance measurement apparatus and a distance measurement method are provided. The apparatus includes a line-shaped laser transmitter, an image sensing device and a processing unit. The line-shaped laser transmitter transmits a line-shaped laser, and the image sensing device senses the line-shaped laser to output a line-shaped laser image. The processing unit receives the line-shaped laser image, and segments the line-shaped laser image into several sub-line-shaped laser images. The processing unit further calculates a vertical position for a laser line in each sub-line-shaped laser image, and outputs each distance information according to the corresponding sub-line-shaped laser image and a transformation relation.
