LD07
LD07 is a short-range one-dimensional solid
laser radar, small in size and low in price, especially
suitable for obstacle avoidance applications of
robots.
The LD07 is a short-range solid-state radar with
a range of 30-300mm. It is mainly composed of a
linear laser and cameras. After the laser is sending
out by the linear laser device , it is captured by the
camera. Based on the fixed structure of the laser and
the camera, combining with triangulation measuring
principle, we can calculate the distance between the
object and LD07.Then according to the camera fixed
parameters , we can get the angle value of the
measured object in the radar coordinate system .
Thus , we obtain the complete point cloud map of
target object.
The common usage of LD07 obstacle avoidance
applications 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.
