LD07 is a short- range one – dimensional solidlaser radar, small in size. and low in price, especiallysuitable for obstacle avoidance applications ofrobots.

The LD07 is a short-range solid-state radar witha range of 30- 300mm. It is mainly composed of alinear laser and cameras. After the laser is sendingout by the linear laser device, it is captured by thecamera. Based on the fixed structure of the laser andthe camera, combining with triangulation measuring principle, we can calculate the distance between theobject and LD07. Then according to the camera fixed parameters，we can get the angle value of themeasured object in the radar coordinate system. Thus，we obtain the complete point cloud map of target object.

The common usage of LD07 obstacle avoidanceapplications is shown as the figure below.

Two laser lines are installed. in the front side towards the ground at a certain angle to measure the distance and angle of obstacles. Alternatively, another one is installed on the side and the laser line is emitted vertically to the ground for walking along the edge of the obstacle. This method is especially useful for avoiding low obstacles such as electric wires, slippers and carpets etc.
