The present invention provides an image acquisition device and an image acquisition method. The image acquisition device comprises: a light emitting unit used for emitting light rays toward an image acquisition area; a receiving unit used for receiving reflected light rays of the emitted light rays reflected by the image acquisition area; an acquisition unit used for the acquisition of the image of a first position point that reflects the emitted light rays in the image acquisition area; a timing unit used for obtaining the emitting time of the emitted light rays and the receiving time of the reflected light rays, and calculating the time difference of the receiving time and the emitting time based on the emitting time and the receiving time; a calculating unit used for calculating the distance between the image acquisition device and the first position point based on the time difference; and a scanning unit used for adjusting the emitting direction of the emitted light rays in the image acquisition area for an predetermined time interval. By using the image acquisition device and the image acquisition method, depth image data output can be completed, and the device has the function of depth perception.
Description
technical field [0001] The present invention relates to the technical field of image capture, in particular to an image acquisition device and an image acquisition method. Background technique [0002] At present, image capture technology is developing rapidly and is widely used. Now there are many high-precision and multi-functional imaging devices on the market, such as cameras, still cameras, and video cameras. [0003] Generally, pictures or images taken by various camera devices in the prior art can only reflect the image of the object to be photographed, but cannot reflect the distance between the camera device and the object to be photographed. However, there are also some shooting situations that require surveying and mapping in life. For example, in the identification of traffic accidents, in addition to obtaining the image of the object to be photographed, if the distance between the camera device and the object to be photographed is determined by perception at the...
