The movable platform is provided with an imaging device and a point cloud acquisition device, the imaging device is used for acquiring two-dimensional images, and the point cloud acquisition device is used for scanning a target object to acquire three-dimensional point cloud.

The point cloud acquisition devices include, but are not limited to: laser radar, binocular vision sensor and structured light depth camera.
The laser radar is used for transmitting a laser pulse sequence to a target object, receiving the laser pulse sequence reflected from the target object and generating a three-dimensional point cloud according to the reflected laser pulse sequence. In one example, the lidar may determine a time of receipt of the sequence of laser pulses reflected back, for example by detecting a rising edge time and/or a falling edge time of an electrical signal pulse. In this way, the lidar may calculate TOF (Time of flight) using the Time of receipt and Time of transmission of the laser pulse sequence, thereby determining the distance of the target object to the lidar.

The structured light depth camera projects light rays with certain structural characteristics to a target object for collection, and the light rays with certain structures can collect different image phase information due to different depth areas of a shot object and then convert the image phase information into depth information so as to obtain three-dimensional point cloud. The structured light depth camera also belongs to an autonomous light emitting sensor, does not depend on light source illumination, is less interfered by ambient light, can normally work even in a lightless closed environment, and has wide applicability.
The two-dimensional images that the imaging device can collect include color images, grayscale images, infrared images, and the like. The imaging device includes at least one or more of: visible light cameras, grayscale cameras, and infrared cameras.

The shooting parameters may include exposure (e.g., exposure time, shutter speed, aperture, film speed), gain, gamma, region of interest, binning/sub-sampling, pixel clock, offset, trigger, ISO, etc. The exposure-related parameter may control the amount of light reaching an image sensor in the imaging device. For example, the shutter speed may control the amount of time light reaches the image sensor and the aperture may control the amount of light reaching the image sensor in a given time. The gain-related parameter may control the amplification of the signal from the optical sensor. The ISO may control the level of sensitivity of the camera to the available light.

In one implementation manner, the remote control terminal can control the point cloud acquisition device to perform supplementary scanning on a target object according to the density of the three-dimensional point cloud so as to additionally acquire the three-dimensional point cloud; for example, a density threshold is set, and when the density of the three-dimensional point cloud in a certain area is smaller than the density threshold, the point cloud acquisition device is controlled to perform supplementary scanning on the area of the target object.
In another implementation manner, in consideration of the fact that an imaging device is used to acquire a two-dimensional image while a point cloud acquisition device is used to acquire the three-dimensional point cloud, and the acquisition ranges of the imaging device and the point cloud acquisition device are at least partially overlapped, so that the two-dimensional image can play a reference role, the remote control terminal can acquire a pre-acquired two-dimensional image corresponding to the pre-acquired three-dimensional point cloud, and control the point cloud acquisition device to perform supplementary scanning on a target object according to a comparison result between the pre-acquired three-dimensional image indicated by the pre-acquired three-dimensional point cloud and the pre-acquired two-dimensional image, so as to additionally acquire the three-dimensional point cloud.
