Definitions
- Fig. 8 is a schematic block diagram of an unmanned aerial vehicle provided by an embodiment of the present application.
- Figure 9 is a schematic block diagram of an unmanned aerial vehicle in another embodiment.
- the light intensity sensor outputs an analog electrical signal under lighting conditions
- brightness information can be determined according to the analog electrical signal output by the light intensity sensor.
- the photographing device further includes a color camera.
- the color camera can also be controlled to photograph the target plot to obtain a color image; and according to the color image Image enhancement is performed on each reflectance image.
- the attitude adjustment is controlled according to the target state of the attitude adjustment device corresponding to the current attitude of the light intensity sensor device, so that the angle between the detection direction of the light intensity sensor and the horizontal plane is basically equal to the preset value.
- the status of the attitude adjustment device may include at least one of the following: the rotation direction, rotation range, and rotation position of the motor in the attitude adjustment device.
- the controlling the attitude adjustment device to adjust the attitude of the light sensor according to the current attitude of the UAV and the installation relationship between the UAV and the light sensor includes: according to the The current attitude of the unmanned aerial vehicle and the installation relationship between the unmanned aerial vehicle and the light intensity sensor determine the current attitude of the light intensity sensor; control the attitude adjustment device to adjust the light according to the current attitude of the light intensity sensor Strong sensor pose.
- the method further includes: when the current sun altitude angle is greater than or equal to a first altitude angle threshold, controlling the attitude adjustment device to fix the light intensity sensor.
- the current unmanned aerial vehicle In order to ensure the compensation effect for the change of ambient light, the current unmanned aerial vehicle usually requires the completion of data collection between 12:00 noon and 2:00 p.m. when the sun altitude angle is basically the highest in the day, but This also greatly shortens the operation time, which is not conducive to carrying out large-scale data collection operations.
- the operating area can be obtained by the terminal device according to the user's area setting operation, or obtained by the position sensor mounted on the unmanned aerial vehicle or the terminal device.
- the position sensor includes, for example, a GPS sensor, an RTK sensor, and is certainly not limited to this.
- the operation area may also be a latitude and longitude, or an administrative division, or a geographical area.
- the determination of the operation time of the second sun altitude angle information it can be made that during the operation time, the brightness information collected by the light intensity sensor is less affected by the flight direction and/or attitude of the unmanned aerial vehicle, and the brightness information more acurrate.
- the sun altitude angle during the operation time is relatively high, and it is difficult for the light intensity sensor to face the sun due to the adjustment of the attitude or flight direction of the unmanned aerial vehicle, which can avoid or reduce the light intensity when the unmanned aerial vehicle adjusts the flight direction or attitude.
- the brightness information collected by the sensor changes greatly, so that the streak phenomenon on the image after the light compensation processing can be reduced or eliminated.
- the second elevation angle threshold is determined according to the performance of the light intensity sensor. So that when the sun altitude angle is greater than the second altitude angle threshold value, the unmanned aerial vehicle adjusts the flight direction or attitude, and the brightness information collected by the light intensity sensor changes little, and the angle of the sunlight incident on the light intensity sensor can also remain basically the same , the data collected by the light intensity sensor is more accurate. Therefore, it is possible to provide an operation time that matches the optical characteristics of the illumination sensor and can ensure that the optical sensor effectively collects data, and helps the optical sensor to collect effective data.
- the unmanned aerial vehicle When the unmanned aerial vehicle is flying, by adjusting the angle between the detection direction of the light intensity sensor and the horizontal plane to be greater than or equal to the preset value, it is possible to make the unmanned aerial vehicle have different headings and Attitude, the angle of sunlight incident on the light intensity sensor can also be kept basically the same, so the influence of the flight direction and/or attitude of the UAV on the brightness information collected by the light intensity sensor can be reduced, and more accurate brightness information can be obtained.
- the attitude adjustment device is controlled to fix the light intensity sensor.
- the second solar altitude angle information of the operation area on the operation date is determined.
