Solid LiDAR CE30-D for UAV
CE30-D is a complete solid-state LiDAR with large measuring range and high resolution. It can be used in UAV such as drones, cars, robots and so on to detect the range, altitude holding, obstacle avoidance, self-guiding and so on
Feature: Complete Solid-state LiDAR
Large measuring range: max to 30 meters with centimeter-level accuracy
High resolution: angular resolution reach to 0.19 degree (3 mrad)
Principle of Ranging: The ranging principle of CE30 is based on Time of Flight (TOF). The modulated near-infrared light is emitted from CE30, which will be reflected by an object and received by CE30 again. CE30 calculates the phase difference and time difference between the emitted and received light to determine the distance between CE30 and detected object.
Blind Zone: When detecting objects with high reflectivity, a blind zone as shown in Figure 4 would appear. This is caused by the overexposure when objects’ reflected light is excessive. LiDAR will filter the data from this overexposure zone. When the detected object’s reflectivity is lower, the blind zone can become smaller. The blind zone is 30 cm long when detect objects with 10% reflectivity.
Detection Range: The maximum detectable range is different in different area of field of view. The detectable area of a 90% reflectivity object is shown in Figure 5.
CE30-D Data Package Form :CE30-D is a 320*24 solid state array LiDAR. It has 6400 photoreceptors.
CE30-D output data row by row. Data of 320 rows is divided to 27 data packages, and each data package will contain 12 rows’ data. The first 26 packages have 12 rows’ measuring data. The last package will contain 8 rows’ measuring data and 4 rows’ padding data.
Each column data corresponds to a certain horizontal deflection angle, and each row data corresponds to a certain vertical deflection angle. Vertical deflection angle is defined in Table 2.
Each data package contains header, data block, time stamp and factory information. The size of each package is fixed to 816 bytes.
