Abstract:
A camera drone with a function of providing real-time captured images in a certain angle (e.g., vertical to the horizon) is disclosed. The camera drone includes multiple rotor wings, a support structure, a wireless transmitter, a controller, and a camera device. The camera device includes a processor, a gravity sensor, a gyroscope, and an image module. The image module is configured to capture an original image in a real time manner. The gravity sensor and the gyroscope are used to calculate a current dip angle (i.e., inclination of a geological plane down from the horizon) of the camera drone. The current dip angle is used to calculate an angle of rotation. The camera device then generates an edited image based on the original image and the angle of rotation.
Abstract:
The disclosed technology is directed to a housing structure with a battery cover. The housing structure enables a user to easily swap a battery positioned therein. The housing structure includes a housing, a push button, a push button cover, and a torsion spring. The housing defines a battery chamber that can accommodate a battery. The push button is positioned adjacent to the housing and supported by the push button cover and the torsion spring. The push button is coupled to a battery cover positioned adjacent to the housing. When a user pushes the push button from the outside of the housing, the battery cover can be moved and/or rotated accordingly such that a gap is formed between the battery cover and the housing. Through the gap, the user can insert a battery into the battery chamber or remove one therefrom.
