LASER RANGING METHOD AND DEVICE

A laser ranging method and device. The laser ranging method comprises: providing a first storage space, and setting an adjustment difference value, the first storage space being used for storing one data; starting laser exposure, comparing data outputted by a TDC in real time with first data in the first storage space, according to the comparison result, adding/subtracting the first data to/from the adjustment difference value, taking the result as updated data and storing same in the first storage space, wherein an initial value is preset for the first data, and the execution of the comparison step stops until the exposure is finished; and determining an object distance measured value according to the value of the first data. According to the laser ranging method, the use of a memory can be reduced, so that the area of a ranging chip is remarkably reduced. L'invention concerne un procédé et un dispositif de télémétrie laser. Le procédé de télémétrie laser consiste à : fournir un premier espace de mémoire et
