Abstract
A method for operating an optical sensor which has a light receptor that receives line-by-line reflected or returned light for a complete picture. At least some of the received pictures are compressed with a picture compression algorithm. To process the picture and more quickly store it in a memory-saving manner, the optoelectronic sensors compress the picture simultaneously with its receipt by the receptor. Optoelectronic sensors for use in this manner can be a code laser or a laser scanner for determining distance or generating separation pictures.
Claims21
A method for operating an optoelectronic sensor comprising providing a light receptor, receiving light returned by an object line-by-line at the receptor until a complete picture is received, and compressing at least one of the received pictures with a picture compression algorithm while receiving the at least one picture.
An optoelectronic sensor comprising a light receptor adapted to receive at least one optical data line;
- a readout device for reading out the optical data line received by the light receptor as a line of signals;
- a picture compression unit for compressing the read-out data line received from the readout device and combining compressed signals into a complete compressed picture defined by the electrical signals, the light receptor being further adapted to receive additional optical data lines while the compression unit compresses previously read-out electrical signals;
- and a unit for using the compressed picture.
