The invention relates to the technical field of house measurement, and particularly discloses a house measurement system based on laser ranging. The system comprises a measurement module for measuringa house distance and features, a control module for controlling the working state of the measurement module, a communication module for real-time remote communication, a data processing module for receiving and processing signals of the measurement module and the communication modules, a display module for displaying information acquired by the system and a storage module for storing the information acquired by the system. The distance data such as the length, the width and the height inside the house are measured through the laser unit, the measurement precision is high, the feature information of the house is recorded through a camera unit, a specific visual impression for the house is achieved, the whole house measurement is more facilitated, a GPS positioning unit is also used to position and collect the real-time position information of the house through a satellite, and through the measurement system, complete house information can be acquired.
