performance improvement

◆300 to 500 metersOperating altitude, matching typical multi rotor flight altitude

◆Point frequency adjustableTransmission power, more flexible selection

100KHZ has strong energy, long range, and strong penetrability

350KHZ long range, high point cloud density, strong penetrability

value point

◆ Improve homework height, enhance homework efficiency and safety

◆ Reduce homework height and improve point cloud density and penetration

◆ Adapt to more terrains and work scenarios

Small spot, strong penetration

Performance improvement:

·L3 spot area is less than 1/5 of L2

Value point:

·More penetrative,More ground points under the forest

·Can beDistinguish smaller target objects(such as wires, towers), obtaining more detailed and complete models

scanning mode

Linear scanning, zigzag scanning, non repetitive scanning

Repeated scanning in the shape of a meter

Function improvement:

·Add repeated scanning of rice characters

Value point:

·Repeatedly scan one word,Scan more evenly and with higher accuracySatisfyHigh precision surveying and mapping requirements;

·Non repetitive scanning,Multiple emission anglesWith stronger penetration, cocoa can obtain morestructural informationSuitable for power inspection scenarios;

·New additionMi shapedRepeat scanning,Balancing penetration and accuracy, suitable for high canopy density forest areas or densely built areas, obtainMore ground point information.

100-2000kHz adjustable point frequency

Performance improvement:

·L3 100000Maximum energy per second, four pairshigherworking height

·Maximum point cloud sampling frequency of L32 million points per second, maximum support16 echoesAccurately depict geographical information.

Value point:

·Requirements for point cloud density and penetration in different scenariosAdjust point frequency, can be obtainedVery goodThe density of ground points.

high precision

Performance improvement:

·3 cm elevation, 4 cm plane (120 meters)

·5 cm elevation, 7.5 cm plane (300 meters)

·Point cloud thickness 2cm (300m orthorectified)

Value point:

1:500 accuracy data can be obtained at a height of 300 meters

At a height of 500 meters, 1:1000 accuracy data can be obtained

100 million pixel visible light module

Performance improvement:

·Double 100 millionpixel4/3CMOScamera

·Mechanical shutter, with a lifespan of up to500000 timesThe cost of homework has been further reduced.

Value point:

·100 million pixelsUsed inHigh altitude operationsHigh resolution guaranteeHomework accuracyAt a working height of 300 meters, GSD can still reach3cm/pix(Typical values, with curves in the manual)

·Support four pixel in one synthesis25 million pixelsSmall photo volume, short photo interval, large single pixel size, better sensitivity, suitable forLow flying sceneOr it may be necessaryPoint cloud coloringScenes with weak ambient lighting or low requirements for visible light resolution.

Dual visible light surveying camera

Performance improvement:

·Dual visible lightDesign of surveying cameras to increase the lateral FOV to107°, protectThe coverage of a single photo is wider

Value point:

·The most typical simultaneous requirement for terrain surveying isDOM和DEMThe field quantity is measured using laser beam in the lateral direction20% overlapIt can be done in one go to improve homework efficiency.
